The post How Do I Determine Which 3D Scanner Is Right For Me? appeared first on GoMeasure3D.

From our experience working with professional 3D scanners day on a regular basis, it’s the 3D scanning software that greatly affects the performance and the user experience. However, it’s the one thing that often gets overlooked when it comes to deciding on which 3D scanner to buy.

For example, if the decision comes down to two systems and stated technical specifications on the datasheets are similar, the price of the cheaper 3D scanner often appears to be the more attractive option. However, this might only be a short-term gain. It might turn out that the less expensive option might end up costing you more—and give you more headaches—in the long run. That’s because qualitative factors (e.g. the user experience) are not given as much weight to the buying decision as quantifiable ones (e.g. price).

Let’s take an in-depth look at why the power is in the software. We’ll also provide tips along the way on what you should look for when evaluating the 3D scanning software during your buying process.

Reason #1

The 3D scanning software is the brain of the entire operation.

It’s easier to visualize the importance of 3D scanning software if we compare it to our own human body. Our body is made up of physical parts (arm, legs, torso, head, etc.). The brain plays an integral role in making sure our systems are well-regulated and our body parts are functioning properly.

If you think about it, the hardware of a 3D scanner is similar to our body parts while the 3D scanning software functions as the control center.

	Physical Components	Control Center
Human	Body Parts (arms, legs, stomach, head, etc.)	Brain (Controls the body)
3D Scanner	Hardware (cameras, lenses, etc.)	3D Scanning Software (Controls the 3D scanner)

Just like our brains, it’s the algorithms inside the 3D scanning software that make the 3D scanner run and perform the essential operations.

• The 3D scanner uses the capturing unit to take images from the real world.
• The 3D scanning software processes this information to acquire the data needed to create 3D scans. It uses the images to calculate the object’s depth and surface information.
• The software cleans up scan data, aligns the scans, and stitches them into a full 3D model.

Without the software, the 3D scanner is just a bunch of hardware parts that are uncoordinated and not very useful.

Tips on Buying a 3D Scanner

When you are looking to buy a 3D scanner, don’t overlook the 3D scanning software because they are not created equal. Some manufacturers spend a lot of time developing and improving their software while others don’t. If you are getting a 3D scanner demo, check to see if you like the software as you will be using it quite a lot once you buy the equipment.

Reason #2

The 3D scanning software can make or break the user experience.

Have you ever used clunky software that you wished didn’t hinder you from getting your work done? Technology is supposed to help you make life easier. However, it can be super frustrating when it makes it harder to accomplish your goals.

The 3D scanning software contributes a big part to the user experience. The user interface (UI) is what you use to interact with the 3D scanner to accomplish specific tasks. This includes acquiring 3D data from the real world to cleaning up scans to create a full digital 3D model.

Our team has used different types of 3D scanners, from handheld to stationary as well as consumer to professional ones. From our experience, here are some of the factors that contribute to a good versus bad user experience.

• 

  Good 3D Scanning Experience

  • The toolsets are easy to use and do exactly what they are supposed to do. It has all the tools you need to perform 3D scanning and post-processing of scans.
  • The workflow is smooth and intuitive. The time it takes to scan an object and to process it into a full 3D model is fast while getting high-quality results.
  • The 3D scanning software makes complicated tasks easy to accomplish. It does all the hard work for you while giving you control when you need it.
  • Think about the little things that can dramatically improve the flow and usability of how the 3D scanner functions.
  • Quick to launch. Continually saves as you work, so nothing is lost if there is a power outage or OS crash.
• 

  Bad 3D Scanning Experience

  • The software crashes and lags all of the time.
  • It can’t handle large scan data.
  • Poorly designed user interface. You can’t easily find the tools you are looking for.
  • It’s very restrictive in terms of its toolsets. It doesn’t allow you to do much.
  • The 3D scanning software doesn’t produce good results as stated in the 3D scanner’s datasheet (e.g., accuracy and resolution).

When a company invests a lot of time and effort into R&D, its 3D scanning software is optimized to get the best scan results. A lot of hard work goes into the technical development of a great 3D scanner to make it work so effortlessly. That’s why you get a great user experience. Everything works so well that it makes 3D scanning look and feel so easy. The quality is reflected in the design of the hardware and software.

Tips on Buying a 3D Scanner

As we’ve mentioned earlier, the price tag on the low-cost 3D scanner might be attractive during the buying process but it shouldn’t be your sole deciding factor. You need to consider both quantitative and qualitative factors when deciding which 3D scanner to buy. Think about the possible customer support issues and the frustration you might have to endure in the long run if you went with the less expensive option. Is it really worth it?

Another consideration is that there is no third-party regulatory body that sets a standard of what 3D scanner manufacturers put on their datasheet (e.g., accuracy, resolution, etc.). Therefore, the best thing to do is to ask for a live demo (in person or web demo) and check to see if the quality of the scan data is suitable for your application. You can request to get the scan data after the demo and then check to see if it meets your standards.

Reason #3

Simply upgrading the 3D scanning software to the latest version can dramatically boost performance.

One of the common questions we often get asked when our customers are looking to upgrade their equipment is, “When is Artec coming out with a brand new 3D scanner?”

If you want a boost in the performance of your existing 3D scanner, sometimes all you need to do is simply upgrade the 3D scanning software to the latest version. For a fraction of the price of buying a completely new 3D scanner, it can make a big difference in the quality of the scan data.

Example: How Artec Studio’s HD Mode demonstrates that even a 6-year-old Artec Eva can perform like a brand new 3D scanner

The Artec Eva we use in our lab is about 6 years old. When we updated the Artec Studio 3D scanning software from a previous version to version 15 with HD Mode, the scan quality improved drastically.

What is Artec Studio’s HD Mode?

Artec’s software engineers have developed powerful algorithms that use machine learning and Artificial Intelligence to extract more resolution from hardware that has reached the limit of its physical optics. The powerful algorithms in HD Mode are capable of doubling the resolution of the 3D scanner without any hardware upgrade.

Check out the difference in scan quality (SD vs. HD) in this video:

HD mode demonstrates that a powerful software can really push the limits of what the hardware can do—even if the physical components are exactly the same as before.

Tips on Buying a 3D Scanner

It’s important to know if the 3D scanner manufacturer is committed to making updates to their 3D scanning software. If you think about it, you can extend the longevity of your 3D scanner simply by upgrading the software—that’s only if the 3D scanner manufacturer does software updates consistently.

A question you should ask when buying a 3D scanner is how often does the 3D scanner manufacturer do software updates? That’s an indication that the company is dedicated to improving the 3D scanning experience for its customers.

For example, every year Artec has one major software release update to Artec Studio 3D scanning software. This means that the company is willing to invest its resources in continuously making its proprietary software perform at its best.

Reason #4

A good 3D scanning software empowers both beginners and experienced users with a variety of tools that are flexible to their skill level.

A great 3D scanning software is one that works for users with different skill levels, from novices to power users. It provides step-by-step assistance to those who are just getting started on 3D scanning while empowering advanced users with full access to the controls to create a 3D model exactly the way they want it.

Example: Artec Studio has different workflows for different types of users.

• 

  Autopilot Mode

  Best for beginners

  Users are guided through a few questions about the object. The software deletes any unwanted captured data, auto-aligns the scans with one click, and instinctively selects the most effective 3D algorithms to create a high-precision 3D model.

• 

  Manual Mode

  Best for advanced users

  Users have a full range of powerful tools to manipulate 3D scan data. Get the best 3D scanning results exactly the way you want.

• 

  Embedded Applications (SDK)

  Best for developers

  Artec Studio software has a powerful set of tools and libraries for anyone who wants to embed 3D scanning into your hardware or software. This can be a perfect solution for medical or industrial applications for automated robotic 3D scanning.

You shouldn’t feel the 3D scanning software is limiting you as you are learning the basics of using a 3D scanner to becoming a power user. Once you become an experienced user, you have control over the settings to get customizable results.

Tips on Buying a 3D Scanner

You can ask your vendor how the 3D scanning software adapts to different types of users. Does the software have different interfaces for beginners and advanced users? How accessible are the tools? Is there continuity between software updates (e.g., it’s easy to use the software from one version update to the next)?

Reason #5

The 3D scanning software can push the capabilities of what it can do beyond just 3D scanning.

Nowadays, most 3D scanning software that comes with the 3D scanner will have basic 3D capturing and post-processing functionalities. If you need a 3D replica of a physical object or a scene, that’s usually all you need out of a 3D scanner.

However, a lot of times getting a 3D model is only the first part of a bigger process or a goal you want to achieve. For example, if you need to do reverse engineering, CGI, inspection, or 3D printing, wouldn’t it be great if the 3D scanning software included these capabilities so you don’t have to buy additional software?

Example: Artec Studio has the following capabilities without leaving the 3D scanning software.

Reverse Engineering	Construct CAD primitives: Toolset to create a variety of CAD primitives from scan data. They can be exported to other CAD software for precise engineering of parts. Create section slices in DXF format and continue reverse engineering in any other CAD software without extra plug-ins.
Inspection	Comparing scans or scan to CAD: Deviation map comparing one mesh to another mesh or CAD file. It shows the high and lows between two compared surfaces. Create inspection reports directly inside Artec Studio if you have Geomagic Control X
CGI	Photogrammetry, retexture your model with images from a professional digital SLR camera, control your lighting, and more.
Mesh Editing	Erase, smooth, defeature, fill holes, filter out hidden or floating polygons.
Decimation	Simplify and keep features, or hit a target polygon count.
3D Printing	Make watertight meshes. Export to STL for 3D printing.

Tips on Buying a 3D Scanner

You can save you money from purchasing extra software if the 3D scanning software has more capabilities for downstream applications. It also streamlines your processes so you can achieve your goals faster. When you are doing a 3D scanner demo with a vendor, let them know how you plan on using the 3D scanner. They can tell you if the 3D scanner has all the tools you need to accomplish your application or you would need additional software to get to your goal.

Final Considerations

The computer you will be running the 3D scanning software also shouldn’t be overlooked when you are purchasing a 3D scanner. 3D scanning requires a powerful computer to process scan data, whether it is a workstation or a laptop. Having a weak computer can cause lagging issues which slows down the performance, even if you have a great software. Ask your vendor for computer or laptop recommendations, or computer requirements essential for the 3D scanner to run at its optimal performance.

As new innovative technology is coming out in the 3D scanning industry, you don’t have to rely on having a powerful computer to operate the 3D scanner. For example, Artec recently introduced a cloud computing option called Artec Cloud for its own line of handheld 3D scanners so you don’t need to use your computer to process scan data. It’s all done in the cloud. Artec Cloud allows you to upload and process projects using their servers, with a full set of processing tools available through any web browser or operating system so you don’t have to depend on your computer’s processing power.

We hope this article will help you get a better understanding that 3D scanning software plays an important role in a 3D scanner. It’s important to thoroughly evaluate the software before buying so you don’t regret your purchase.

You’ve spent countless hours doing the research and have come to the conclusion that having a 3D scanner will help you tremendously with your work. It’s time to approach your manager in order to give you the green light on the purchase.

The only problem now is to convince them that this 3D scanner purchase will turn out to be a great investment for your company.

How do you present the value of a 3D scanner so they will approve?

Good news! We’re here to help

Let’s take a look at why having a 3D scanner is a great investment, specifically for:

Reverse engineering (Scan to CAD)

Quality inspection applications

Why Invest in a 3D Scanner for Reverse Engineering Applications

Reverse engineering is the process extracting knowledge from a manufactured part to understand its design and construction. The goal is to create documentation in order to make a new one.

Reasons for reverse engineering include:

• Creating CAD file for legacy parts where no drawings or CAD are available
• Improving or changing the design of existing products
• Building components that fit perfectly with existing products (e.g. accessories, casing or packaging for electronics)
• Repairing worn or broken parts (e.g. old car parts)

Let’s look at the conventional and modern approach to reverse engineering and see how they differ.

Conventional Approach to Reverse Engineering

Measuring Using Hand Tools

Traditional methods of reverse engineering use tools such as vernier calipers, micrometers, tape measurements, or gages for taking critical surface measurements of the object manually by hand. Then, the operator would use the collected measurements to design the CAD model from scratch using CAD modeling software.

Modern Approach to Reverse Engineering (Scan to CAD)

Taking 3D measurements using a 3D scanner

The modern approach to reverse engineering is known as Scan to CAD. As its name suggests, it’s using scan data from a 3D scanner as a guide to create the CAD model.

The operator uses a 3D scanner to take 3D surface measurements of the object. Each measurement point contains accurate XYZ coordinates. Certain 3D scanners, such as a structured-light 3D scanner, can capture millions of data point from one 3D scan in just one second. The scan data is then used as a guide to sketch the part. It’s similar to tracing in order to speed up the time it takes to create the CAD model.

Scan Data to CAD – How It Works

Why Scan to CAD?

Using Scan to CAD approach to reverse engineering looks a lot different than using hand tools. The process is a lot less labor intensive, which is a time saver. Best of all, it gives you all the information you need to build the CAD file properly and accurately too. There’s no guesswork for less headaches and frustrations.

Hand measurements are traditionally linear by nature. What can be assumed to be a straight line to the eye may in fact be a spline. It’s difficult to figure that out using conventional measurement tools.

To the eye, it looks like the pipe has the same thickness throughout its length. When measuring from just one edge, the tube would seem to have an unnecessary bend. Using a 3D scanner, you can see exactly why this is the case.

It is easy to find the diameter of a hole with a caliper.

• But is the hole round?
• And where is the hole located in relationship to other elements of the part?
• Is the hole perpendicular to the surface normal?
• Is the surface flat or organic in shape?

These are questions that traditional measurement tools struggles to answer but a 3D scanner can answers these questions quickly and with certainty.

With hand tools, understanding geometry location in 3D space (XYZ) can be difficult, in terms of how features of a part relate to one another. 3D scanner gives you a better picture with full coordinate in 3D space and feature information of any component.

Scan data from a 3D scanner gives you the ability to understand and interrogate the part to a much greater detail compared to measurements taken with hand tools. The scan data is also very accurate, with some 3D scanners generating up to 25 micron accuracy per scan. You need reliable data you can trust for making important decisions.

Conventional Way Hand tools for simple, straightforward jobs	Scan to CAD Structured-light 3D scanner for more sophisticated projects
Take one measurement at a time (Slow)	Each scan captures about 1+ million 3D surface measurements in under 1 second (Efficient)
Measures basic prismatic parts but not sophisticated enough or practical to measure complicated parts or organic surfaces. There are surfaces or features that are very difficult to measure, if not impossible, to recreate without 3D scanner. (Limitations)	Measures parts with organic and complex shapes (Versatile)
More prone to human error due to variations in how measurement procedures are carried out (Not very accurate)	Non-contact measurement device with sub-thousands of an inch accuracy (High accuracy)
Efficient for simple jobs (Little to no training required)	Requires basic training to learn the process (Training required)
Slower process, in terms of time it takes to take measurements by hand and waiting for engineers to work on CAD drawings from scratch (Creates bottleneck)	Efficient at reverse engineer parts with quicker turnaround times for creating CAD models by using scan data as a visual guide for design. Speed up product development cycles for faster time to market. (Minimize bottlenecks)
Can’t take too many measurements within a time constraint (Limited intelligence)	By collecting and extracting more intelligence about the existing product in a short period of time to understand the design intent, you hold the power to design better products. (More knowledge)
Inexpensive	More costly

Cultivate Creativity and Innovation

Another advantage to using the Scan to CAD process is that it inspires innovation in product design.

3D Scanner (Hardware) + Reverse Engineering Software

Scan to CAD solution includes the purchase a 3D scanner and reverse engineering software to create the CAD model once the scan data is collected. The cost can vary depending on how accurate you need the 3D scanner to be, as well if you need basic or advanced reverse engineering software package.

Scan to CAD solution can range from $7,500 for a basic solution to $35,000+ for a high-end solution (in US dollars). Contact us if you would like to learn more about these solutions.

Money Saving Tip for Scan to CAD

If you are, there are low-cost reverse engineering plugins that work directly with the 3D scanner to help you reverse engineer from SCAN to CAD without spending too much. Advanced standalone reverse engineering software, which contain a full set of comprehensive features, can be quite an expensive investment for a small to medium sized company. Plugins that work directly with CAD modelers are substantially cheaper and they still get the job done.

As an added advantage, these reverse engineering plugins works natively inside these CAD modeling programs, so you don’t have to learn an extra piece of software. Contact us if you would like to learn more about these solutions.

3D Scanner ROI: Time and Money Savings (For Basic Reverse Engineering Applications)

From our 19 years of experience working with our clients on Scan to CAD projects, we see a typical return on investment on Scan to CAD solution can range from approximately 2-4 months, depending on the complexity of your application as well as how much you invest in the solution.

Below are some examples of approximately how much time and money saved by investing in a 3D scanner using a basic mechanical part.

Scenario 1: Reverse Engineering a Basic Mechanical Part (Per Part)

Manually using Hand Tools Time it takes to reverse engineer: 8 hours

Scan to CAD using 3D Scanner Time it takes to reverse engineer: 2 hours

Time Saved using Scan to CAD Time saved using Scan to CAD approach: 6 hours

Save $300 per part Based on average work cost of $50 per hour = 6 x $50

Cut Down Time by 75% Scan to CAD takes about ¼ of the time it would take compared to doing it manually by hand.

Scenario 2: Reverse Engineering a Basic Part with Organic Surfaces (Per Part)

Manually using Hand Tools Time it takes to reverse engineer: 13 hours

Why Invest in a 3D Scanner for Quality Inspection Application

Quality inspection compares the measurements of a manufactured part against the design blueprint to see if it meets acceptable standards (tolerance).

It’s important to have a solid quality inspection process. Having a good one in place ensures your company is manufacturing products at the highest standards.

Let’s see how the traditional way of part inspection is different from the modern approach using a 3D scanner for measurement.

Conventional Approach to Part Inspection

Measuring Using Hand Tools

The operator first takes selected critical measurements using hand tools and compare them to the CAD model. Height gauges, calipers, and micrometers being used on a surface plate are traditional ways of doing quality inspection but this process can be tedious and time consuming.

Modern Approach to Part Inspection (3D Inspection)

Taking 3D measurements using a 3D scanner

The operator uses a 3D scanner to capture millions of measurements per scan of the physical part and then compare them to the CAD model. 3D scans can be compared to CAD quickly and accurately using 3D inspection software. It enables the operator to see deviations of the manufactured part compared to the master model for any surface measurements.

Why 3D Inspection?

Imagine getting the most comprehensive reports with visual reference of the measurement deviations between a manufactured part to CAD. You can pinpoint exactly where the problem areas exist and work on fixing them immediately. This can be accomplished using a 3D scanner and 3D inspection software.

One of the common inspection applications we’ve seen from working with our customers is for checking for tooling wear and tear. For example, tool and die makers need to inspect their hot stamping die when it is not manufacturing products properly. It’s sometimes difficult to understand what the problem is with hand tools, and in some cases even portable CMMs, as you can only take limited measurements to uncover the root of the problem. This can cause production to come to a halt.

Tool and die makers can avoid costly tooling error and time delays with an accurate 3D inspection solution. The operator can take a scan of the die using a 3D scanner, compare it to CAD, and can see exactly where there is wear and tear on the die that is causing manufacturing issues.

3D Inspection:

• Gives you the ability to acquire the most amount of accurate data in the shortest amount of time to understand the problem or to make a decision
• Provides consistency in QA process
• Save on labor cost
• Produce consistently good quality products without defects
• Minimizes human error

Conventional Inspection (By Humans)	3D Inspection (Using a structured-light 3D scanner)
Capture one measurement at one time (Time-consuming)	Each scan captures about 1 million 3D measurement points in under 1 second (Efficient)
More prone to human error during the measurement process. Defects might be missed. (Not accurate)	Non-contact measurement tool with sub-thousands of an inch accuracy (High accuracy)
Can only compare limited number of measurements (critical ones) due to time restraint and practicality to understand the issue. (Limited knowledge)	Ability to compare about 1 million data measurements with CAD model almost instantaneously to get a more comprehensive view of the issue. (More knowledge)
Tooling and first article inspection slowed down by labor intensive processes that takes up time. (Bottlenecks in inspection process)	Ability to measure parts quickly and compare to CAD models to see deviations immediately (Faster)
Inexpensive	Requires equipment investment

3D Inspection Success Stories From Our Clients:

One of our Metal Fabrication customer purchased the HDI 3D scanner with Geomagic Control 3D inspection software to create a heavily automated 3D inspection process for scanning parts approximately 24” in length. They integrated FlexScan3D (3D scanning software that powers the HDI 3D scanner) and Geomagic Control to work together. The customer was happy with the results as they are now able to achieve scan to report time of under 3 minutes with minimal involvement by the operator.

If it’s your first time purchasing a 3D scanner, it can be an overwhelming experience. There are so many 3D scanning solutions out there in the market claiming to have the fastest scan speed, the best accuracy, and can do exactly what you want to achieve.

How do you know which one will actually be able to solve your business problem after purchase?

Your 3D scanning equipment purchase should be an investment that pays off—in the form of cost savings by improving process efficiency, to solve a problem, or to help you achieve better product quality. The worst thing that can happen would be to buy a 3D scanner and to realize later that it doesn’t provide a return for you because you purchased the wrong equipment or it doesn’t perform the way you had expected.

Here are some things you need to take into account to ensure you get the right 3D scanning solution that will produce a return on investment.

Set Clearly Defined Goals

When researching for a 3D scanner to purchase, the first step is to clearly define what you are looking to accomplish. Selecting which solution is best suited for you really depends on your specific application and what results you expect from its implementation.

We have seen clients get really excited about 3D scanning technology and they get caught up on wanting to implement it into their operations in some way without stating a clear purpose.

If you don’t have a clear idea on what you want to achieve it’s difficult to know—and get—what you need to produce results.

It’s easy to assume that if you know what you need inside your head it’s good enough. However, if you outline your thoughts in writing they will become more concrete. You can always refer back to this document as a guide when you are evaluating the different options available to see which one is the best fit for your needs. Otherwise, you will have no criteria to evaluate whether the solutions you are considering will meet those requirements.

Here are some questions to get you started:

1. What challenge(s) you are trying to solve?

2. What specifications do you need in a 3D scanner in terms of:

   • Accuracy: How close do you need the scanner to obtain the true measurement value of the object you are looking to scan?
   • Resolution: How much detail do you need from the 3D scans?
   • Scan size: What type of objects are you looking to scan? Do they vary in size?
   • Color/Monochrome scans: Do you need the scanner to capture color texture?

3. What goals or business objectives would you like to accomplish?

Going through this process of documentation will help you narrow down your options and will steer you in the right course of making the final decision.

Don’t Take Technical Specifications on Datasheets at Face Value

When evaluating similar 3D scanners from various vendors, we often rely on looking at datasheets to compare technical specifications. It’s important to look at the technical specifications on datasheets very critically rather than taking them at face value.

The optics of a datasheet can be weighted to a particular scanner’s strengths. Currently, there aren’t any industry standards to hold each 3D scanning manufacturer accountable to provide technical specifications using the same testing methodology for getting numbers such as accuracy and resolution. These numbers shown by themselves don’t give context. They are affected by variables including field of view being used, environmental conditions, and the type of scan target being used when calculating these numbers.

Consequently, it’s very difficult to compare apples-to-apples when comparing 3D scanners from different manufacturers purely by judging the specifications on datasheets.

The best way to see if a 3D scanner meets your technical requirements is to see the quality of the raw scan data of a similar object you are looking to scan. It serves as evidence to support the numbers written on datasheets. Raw scan data is unmanipulated 3D data captured directly from a 3D scanner without any post-processing. It’s similar to judging the quality of a camera by looking at the photos it takes before the photos get Photoshopped. Reputable vendors will provide you with raw scan samples upon request to help you make the most informed decision.

Your Wants Might Not Match Your Needs

While it is perfectly understandable to want the best solution you can get, you need to make sure that your budget is aligned to what you really need versus what you want. To think of it from another perspective, let’s say you want to buy a new car for your family. Although it’s nice to get a Ferrari or a luxury car to ride in style, it might be an overkill if you just need a simple transportation means to get you to places (also you probably don’t have the budget or want to spend that much money for an expensive ride).

Expensive technology doesn’t necessary translate to it being the best solution for you.

You don’t need to get top of the line if you are going to use a fraction of the features or specifications. It’s important to find the right technology for your needs.

Set realistic expectations and get the solution that gets the job done and works within your budget. Why buy—or pay for—an expensive scanner with the best accuracy and resolution you can get on the market when you don’t need it? Don’t be tempted by spending more on unnecessary features that don’t add value for you.

Get the Support of Your Staff

The key to making sure that the 3D scanner implementation is successful after purchase is to have people within your company to champion its use and have dedicated staff to master the skill of 3D scanning.

It’s a good idea to loop them in during the buying process so they feel they are involved in the project, from procurement to implementation.

It gives them a better understanding as to why your organization is implementing 3D scanning into your processes. It fosters a sense of ownership. Consequently, they would be able to see through your vision to help you succeed in achieving your ultimate goal.

While 3D scanning has become more and more easy to use over the last five years, your employee(s) still need to take the time to learn and train on how to use the 3D scanner for the specific applications you need, whether it’s reverse engineering, inspection, measurement, or 3D visualization.

3D scanning is a skill that gets better with training and experience. Most solution providers will offer training for your staff if required.

Find a Vendor that will Become Your Solutions Partner

When assessing different 3D scanner options from various companies, you need to find a vendor that you can trust as a solutions partner.

There are many vendors out there offering same 3D scanners but what sets a solutions partner versus a product provider apart is the service and experience.

You know if a vendor is a reputable solutions partner if they have years of experience in the area of 3D scanning. During the buying process they are dedicated to going the extra mile to help you find a solution to your problem or challenge. You should feel at ease working with them and they can provide you with valuable information and tips you would never have thought of yourself.

Every project is unique so it is important that your vendor understands your project requirements and helps you figure out the best solution to your challenges. Some vendors also offer technical support along with their products to ensure that you receive assistance post-purchase. Having a vendor as a partner is crucial in making sure that you purchase the right 3D scanning solution for your business.

The post How to Ensure Your 3D Scanner Becomes a Return on Investment (ROI)? appeared first on GoMeasure3D.

Every day, we have great conversations with people who are looking to find the right 3D scanner to help them solve work-related challenges—from quality managers who are looking for a computer-aided inspection system, to archaeologists who want to preserve ancient artifacts into digital formats.

We find a majority conduct their own research before contacting us. There are times when they have already decided on whether to get a stationary or handheld 3D scanner before realizing one might be better suited for their applications after talking with us.

How do you know if a stationary or a handheld 3D scanner is most suited for your needs?

Before you decide, let’s take a look at the two options and the various factors that will influence your decision.

How Stationary and Handheld 3D Scanners Work

A stationary 3D scanner is mounted to an arm or a tripod and it’s fixed at a location. The user turns the object, the scanner captures a scan, and this process continues until all scans are captured of the entire object at various angles. Depending on the processing software, some can automatically merge the scans together during the scanning process or this might be done when all the scans are collected at the end. Individual scans are later stitched together to create one complete digital model.

For a handheld 3D scanner, the user hovers and paints around the object in order to obtain 3D scan data of the entire object. It operates similar to a video camera but it captures objects in 3D with continuous scanning.

Factors to Consider

1. Accuracy and Resolution

   Currently, if you are comparing a stationary 3D scanner to a handheld using the same technology (e.g. structured-light), stationary 3D scanners provide better accuracy and resolution. If your application needs to drive the best possible accuracy and resolution you can get and it’s the most important factor you need in a scanner, stationary 3D scanners would be a good choice.

   The scanner’s scan quality is influenced by how it works. For example, stationary 3D scanners using structured-light technology take a series of images in one snapshot and consolidates the average to generate one scan. Handheld 3D scanners using structured-light technology take one shot per frame (equivalent to one scan) and then the user moves the scanner to take another scan. It’s similar to comparing a still image taken from a camera versus a frame taken from a video recording. The former will get you better quality than the latter. The scan quality is still great for a handheld 3D scanner, but typically the stationary 3D scanner provides slightly better results when comparing scanners that are similar in price point.

   However, it’s important to remember that a majority of applications don’t require the high quality. There are other factors such as portability and ease of use that might be more important to you. A handheld 3D scanner is a great solution for reverse engineering, 3D visualization, and even quality inspection applications if you don’t require the absolute best accuracy and resolution you can find. 

2. Portability

   

   Handheld 3D scanners are synonymous to portable 3D scanning. These scanners give you maximum portability compared to a stationary 3D scanner. 

   You can essentially take them anywhere. For example, Artec 3D scanners support battery operation for scanning offsite in the field for up to 6 hours, even in areas with no electricity. It even supports the use of a tablet to power its 3D scanning software so you don’t have to carry a lot of heavy equipment for your travel.

   A stationary 3D scanner requires a desktop computer or laptop to power the 3D scanning software for data acquisition and post-processing, so you would require electricity to run the system at all times.

3. Scanning large volume of objects with a repeatable process

   

   

   Stationary 3D scanners are a great option if you need to scan similar sized objects in volume quickly. It enables an automated standardized setup without the need for much human involvement to help gain efficiency in the scanning process.

   Automating the scanning process with a stationary 3D scanner is possible when paired with a motorized rotary turntable accessory. The user sets the rotary table to capture a certain number of scans while it spins the object in 360 degrees horizontally. When the rotary table stops spinning at certain intervals, the scanner captures a 3D scan of the object at that particular angle. Once it captures all the scans, the scanner automatically post-processes the scan data by merging and stitching all the scans together into a complete digital 3D model.

   Once the object is completely scanned, the next object would be placed on the rotary table and the process starts all over again. An assembly line workflow to 3D scanning takes out much of the manual labor-intensive work.

   Using Handheld 3D Scanner For Robotic Scanning

   Compared to a stationary 3D scanner, a handheld 3D scanner is normally setup so the user holds the device while scanning. Because human factor is involved, it would be difficult to replicate the exact process every time you scan a set of similarly-sized objects. However, handheld 3D scanner manufacturers are starting to give users an automated, hands-free option with robotic 3D scanning.

   Instead of operating the handheld 3D scanner manually, the scan head is mounted to a robotic arm programmed to move automatically. The scanning station would do it faster and more accurately than if a person is scanning by hand. Robotic scanning is also an option if you are using a stationary 3D scanner.

4. Scanning hard to reach places

   It’s easier to maneuver a handheld 3D scanner compared to a stationary 3D scanner because the scan head is portable. You can easily scan holes or undercuts that would be more challenging to scan with a stationary 3D scanner.

   

   

   Handheld 3D scanners also great for scanning in confined spaces where the object, such as museum sculptures, cannot be moved to a different location for scanning. This scenario would be difficult for a stationary 3D scanner to be placed at a certain distance for scanning, where there isn’t ample space.

5. Field of view

   There are certain stationary 3D scanners in the market where one system is capable of scanning objects of different sizes by adjusting the scanner’s field of view (FOV). Depending on the object size you’re looking to scan, the scanner’s cameras and lenses can be moved to different mounting positions to adjust the FOV.

   

   Handheld 3D scanners have a fixed FOV so it is restricted to the object size it can scan while retaining its accuracy.

   Using the HDI Advance 3D scanner as an example, if a drastically smaller field of view is required to scan an object such as small turbine blade, screw, or small insect with high precision accuracy, the scanner is flexible to be converted into a macro scanner. All you need is to use an add-on accessory kit without the need to purchase an entirely new system. If you need to scan objects that vary in a range of sizes, stationary 3D scanners might be the most cost-effective solution for your needs.

   

6. Ease of Use and Training

   We train our customers on both types of scanners. Overall, the handheld device is an easier technology to pick up and to learn. It requires a shorter learning curve compared to a stationary 3D scanner.

   However, if you are striving for high accuracy and resolution in your 3D scans, it takes more knowledge and training to achieve these results. It’s worth spending more time on training to use a stationary 3D scanner because you want to get optimal performance the equipment has to offer.

Our goal here is to provide some general guidelines to help you start thinking about what factors are most important when deciding on which option is right for you.

It’s always a good idea to contact a reputable 3D scanner solutions provider who can understand your application, what you are looking for in a 3D scanner, and walk you through the different options available. They can also give you a demonstration of the stationary and handheld 3D scanners to help you ultimately make an informed decision.

The post Choosing Between a Stationary or Handheld 3D Scanner appeared first on GoMeasure3D.

If you need a 3D scanner for your upcoming project and you don’t have access to the equipment at your disposal, there are two main options you can consider:

Option 1: Invest in getting 3D scanning capabilities in-house by buying a 3D scanner

Option 2: Outsource your 3D scanning work by hiring a contractor or a company that will provide 3D scanning services for you

How do you know which option is right for you?

Finding the answer to this question really boils down to your requirements. Let’s look at a few factors to guide you in this decision making process.

1. Volume of Work

   Think about the amount of 3D scanning work you need to do in the foreseeable future and see if service work is a more cost-effective solution for you compared to purchasing a 3D scanner. For example, you should consider hiring a service bureau if you need 3D scanning temporarily or if you have a seasonal need.

   While it might seem easier for someone else to handle the scanning portion of the project, the cost of using 3D scanning service work can add-up if you are a frequent user or if you have a lot of objects to scan for a particular project. 3D scanners, even professional systems, are now more affordable than ever before. If you want to embed 3D scanning capabilities into your operations, you should consider buying a 3D scanner, as it can become a valuable asset in the long run.

   

2. Time

   Having 3D scanning in-house provides you with more flexibility as you can use the scanner whenever you need it. If you hire a contractor or a company to do the service work, you have to take into consideration the extra time needed to ship parts back and forth, or the time it takes to correspond with your service provider to make sure they understand your requirements.

   Do you need your object scanned immediately? If so, finding a company that does 3D scanning service work might be your best option. If you need to do 3D scanning frequently and you have some time before you need to use the equipment, then it opens up the possibility of investing in a 3D scanner.

3. Control

   Sometimes, you just want someone else to take care of 3D scanning for you so you can focus on your expertise. If you require additional services such as reverse engineering work (e.g. creating CAD models from scan data) and you don’t have that technical expertise in-house, you can hire a service provider to help you with the work.

   Buying a 3D scanner makes technology more accessible. By having a 3D scanner in-house, your company can use it on demand whenever you need it. Purchasing a 3D scanner also gives you with the control of configuring the 3D scanning process to how you want it to best fit into your business processes. 

   Having 3D scanning in-house provides a tighter control to the security of the scan data. If it’s sensitive information (e.g. scan data related to patient information) you don’t want to disclose outside your company, bringing 3D scanning capabilities internally might be the key.

4. Application

   There are certain applications where you need to buy a 3D scanner in order to integrate it as part of your operations. For example, if you are looking to constantly inspect manufactured parts every day in your production line, buying a 3D scanner makes the most sense—logistically and financially. If you’re looking to scan artifacts at archaeological sites all around the world, it would be more convenient to travel with your own 3D scanner.

   Typically, a specific 3D scanner is good at scanning certain types of objects or objects of a similar size. For example, you would need a different scanner if you are scanning a room versus scanning consumer products or manufactured parts. If you have to scan a few parts varying drastically in characteristics or size, you would need a range of 3D scanners to do the job. In this case, hiring 3D scanning services would be the cost-effective option if you’re not scanning in volume.

5. Expertise

   Service companies have the 3D scanning expertise from doing this type of work for a long time. If you have a demanding 3D scanning project that requires a strong level of skills and expertise to pull it off (e.g. scanning a train to inspect it for wear and tear), hiring 3D scanning services would be your best bet.

   Buying a scanner empowers your staff by developing 3D scanning expertise in-house. 3D scanning is a versatile technology. By having the accessibility of the technology in-house, it drives innovation. Employees have the means to experiment with 3D scanning to create value beyond its intended use. 

6. Budget

   Budget is a big influencer on whether you should buy or hire. If you have the budget to purchase a 3D scanner, you can find a solution that is customized to your exact needs and specifications. If you have a tight budget and consumer-grade 3D scanners won’t provide you with the scan accuracy and resolution you need, you can hire a 3D scanning service bureau with high-end equipment to produce high quality results.

There are quite a few factors to consider when making the decision to purchase or outsource. Ultimately, you need to figure out which factors are the most important to you in order to make the final decision.

Budget is a key factor that contributes to the buying decision. It is a sensitive topic but it needs to be addressed in order to set realistic expectations. When researching on which 3D scanner to buy, one of the things you’ll notice is prices range from less than $1,000 for consumer-grade 3D scanners all the way to upward of $10000+ for professional-grade systems.

We are more likely to be exposed to the low prices associated with consumer-grade scanners. When shopping for a professional-grade scanner to use in industry applications—whether it’s for reverse engineering, quality inspection, or scientific measurement—people are often surprised to find out these systems are substantially more expensive. Why is there such a discrepancy in prices?

Same Functionality, Difference in Quality

We can explain the fundamental difference between consumer-grade versus professional-grade 3D scanners using cameras as an example as the technology is similar to 3D scanners. In terms of functionality, cameras translate the real world in the form of 2D images while 3D scanners take 3D images.

All cameras have the ability to take photos but when you compare a point and shoot camera with a digital SLR, the latter will produce better image quality (i.e. sharper images, better sensitivity to light, less noise/distortion in photos). More expensive cameras like the digital SLRs use high end components (i.e. better sensors and lenses) and therefore produce higher quality results compared to point and shoot cameras. Because digital SLRs use higher quality components that are more expensive, this is reflected in the price.

The same can be said for 3D scanners when comparing consumer versus professional-grade systems. Professional 3D scanners used for industry applications deliver significantly better raw scan data quality, when compared to its consumer counterpart.

How is Scan Quality Defined?

Scan quality is defined as how good the scanner is at capturing raw output (digital 3D measurement coordinates known as point cloud) from the physical environment. The data has not been subjected to post-processing or any other modifications. Scan data quality can be defined by several factors. There is a direct relationship between these factors and price–you will have to pay more for better results.

Accuracy

How true a measurement is to the real value of the object.

For 3D scanners, accuracy is usually defined by depth or dimensional accuracy and it’s the most important aspect for 3D measurement equipment. All measurement devices, including 3D scanners, are not perfect and can never achieve the true measurement value of the object.

Resolution

How many 3D measurement points a scanner collects from the surface of real world objects. Similar to accuracy, you should get the resolution you are comfortable with for your application.

Cleanliness (versus noisy scan data)

Scan data can be noisy if the scanner doesn’t use industrial-grade components (cameras, camera sensors, lenses) to produce high quality results, which you normally don’t see in consumer-grade scanners.

Scan speed also affects the cleanliness of the scan data. If the scanner is scanning slowly and the scan target (i.e. person) moves during the scanning process, it can cause noisy data. If the scanner is fast at taking scans (< 1 second), the effect of slight movement is minimized.

Repeatability

Variations in the measurements taken from the same equipment on the same scan target.

Professional-grade scanners go through rigorous testing to ensure you get the same results every time. When you depend on 3D scan data for decision-making where your company’s reputation is on the line, it’s important to know that the data you are using can be trusted.

What other factors affect 3D scanner price?

Besides scan data quality, other factors affect the price of a 3D scanner.

3D Scanning Software

The 3D scanning software that comes with a professional-grade 3D scanner is more sophisticated, in terms of data acquisition and processing capabilities, when compared with the software found in a consumer-grade scanner. The software gives you more control over the scan data by having more features for data acquisition, cleanup, merging, and aligning 3D scans into a digital 3D model for downstream applications.

Stability to Variations in Environmental Conditions

Professional 3D scanners, typically higher end professional-grade systems, are ruggedly built for tough conditions to withstand temperature fluctuation in the working environment. This is especially important for quality inspection applications where the 3D scanner must be trusted to generate repeatable scanning results every time.

The Best Option Isn’t Necessarily the Most Expensive

There is a quality difference when you look at consumer-grade scanners compared to professional-grade scanners and this is reflected in the price. However, the best 3D scanners out there aren’t necessarily the most expensive. Get what you need for scan quality and don’t overpay for what you don’t need.

Define the factors most important to you by examining what application you will use the scanner for and get the system that best fits your needs. It’s important to get the right tool for the job.
