These two scans were captured by the same 3D scanner.
But why are the results so different?

A major obstacle in getting the best results out of a 3D scanner is mastering the nuances of the 3D capture process, which can be challenging for new users to know if they are just getting started.

For Instance, Did You Know?

• 3D scanning shiny objects can be problematic because reflective surfaces scatter the light projected from the 3D scanner, causing a less-than-ideal condition.
• Repetitive or symmetrical surfaces can make a 3D scanner lose track of its movement while scanning.
• Getting a 3D model in 360 degrees requires scanning the object at all angles, which can be a time-consuming process.

Nevertheless, with practice and determination, anyone can overcome these challenges. You can unlock the potential to achieve remarkable results, elevating 3D scans from average to exceptional!

Our team has spent countless hours testing and understanding what it takes to get accurate and reliable 3D scanning results every time. We would love to share these tips and tricks to take your 3D scanning skills to the next level. Implementing them will make your 3D scanning process a lot easier and faster. Most importantly, get the best resolution and ultra-high accuracy 3D models from your 3D scanner.

First things first. Let’s go over some fundamentals of 3D scanning to understand the basics before we dive into the tips and tricks.

The Golden Rule of 3D Scanning

When you are 3D scanning, it is important to know that you should always:

Aim to capture the highest quality raw scan data from your 3D scanner rather than relying on post-processing algorithms

3D scanners capture raw 3D measurement data of a real-world object in the form of point cloud or polygon meshes.

Raw 3D Measurement Data (Scan Data)

• 

• 

Post-processing is the modeling stage where you clean up and transform individual 3D scans and merge them into a unified 3D mesh.

Finally, the rendered 3D models can be exported in a variety of industry-standard file formats. For advanced applications (such as reverse engineering, quality inspection, or CGI), additional post-processing software may be necessary. However, nowadays advanced 3D scanning software like Artec Studio extends beyond the basic 3D scanning cleanup to handle some of these operations.

3D Scanning Workflow

• 

  Geometry Acquisition

  Data collection phase where the user captures all sides of the object using a 3D scanner.

  Output:

  Raw scan data

• 

  Post-Processing

  3D modeling phase that includes hole-filling, cleaning, aligning, and merging individual scans into a digital 3D model.

• 

  Export for Use

  Making the data available for use in another software by exporting it into standard file formats (PLY, OBJ, STL, ASC, FBX).

  Output:

  3D model ready for industry use

Capturing high-quality raw scans during the data acquisition stage is crucial because post-processing cannot always improve the quality of poorly scanned data. Similar to cooking, fresh ingredients are necessary to create a delicious dish. The same applies to 3D scanning. Obtaining top-notch raw scans during the scanning process provides superior data to work with during post-processing, resulting in better final results.

Consequently, obtaining high-quality raw scan data from the outset ensures that less time and effort will be spent during post-processing, saving time, frustration, and headaches.

So, what steps can we take to make sure that we capture quality scans before post-processing?

Preparing for Success: Build a Strong Foundation

Proper planning and preparation are crucial for every project in order to achieve high-quality 3D scans. By taking the time to prepare, you can simplify even the most challenging projects. The objective is always to do it once, instead of working in a perpetual cycle of re-scanning the object over and over again due to poor planning.

If your 3D scanner produces noisy scan data, this is often an indication for a need to improve either the device settings or the physical setup. Remember, investing in preparation now can save you significant time and effort down the line.

Planning and preparation = Less work later

Here are eight tips to help you capture quality 3D scans from the start:

Get the best scans from your 3D scanner by following these simple tips.

1. Tip #1: Take Control of Your Environment

   

   If you are 3D scanning indoors, have a designated area for this purpose. Creating a controlled environment gives you a better chance of getting consistent scan results.

   While the 3D scanner is acquiring data, excessive movement from the object or the device can create noisy scans and inaccurate results. Make sure you are 3D scanning in an area free from vibration from the ground (scanner placement – this is especially true for desktop or tripod-mounted 3D scanners) or surfaces such as a table (object placement).

   Consistent lighting is also crucial for scanning. Bright lighting can cause noisy data. It is best to switch off or dim the lights for better results.

   Some 3D scanners are capable of scanning outdoors. If you are scanning outside, do it in a shaded area away from direct sunlight with consistent lighting to capture the best scans.

   

2. Tip #2: Use the Right Fixture

   To prevent objects from falling down halfway through the scanning process due to improper mounting, it is essential to fixture them properly. Make sure the object is placed on a stable surface. For objects that don’t sit well on flat surfaces, you can use clay putty or clamps to hold the part in place.

   

   It is important to keep the object fixed securely to the surface. Even though the fixture will be deleted during post-processing, it is an essential component in the 3D scanning workflow. Background objects (or fixtures) like a floor, table, or turntable provide valuable reference points for the 3D scanner. Good fixtures have unique geometric shapes and textures to help the 3D scanner track movement and establish scale.

3. Tip #3: Use A 3D Scanning Spray For Scanning Challenging Surfaces

   

   3D laser scanners and structured-light 3D scanners have difficulties capturing parts with shiny, dark, or clear surfaces. These types of measurement devices use light as a projection source. The light scatters when scanning surfaces such as metal or glass.

   To overcome this challenge, a developer aerosol spray can temporarily coat parts and create a uniform matte surface finish for 3D scanning. In our lab, we use AESUB 3D scanning sprays extensively for our projects and they work very well for 3D scanning applications.

   

   

   

   “Its vanishing spray [AESUB] range is a godsend when trying to capture reflective surfaces.””

4. Tip #4: Rotate the Object While 3D Scanning

   

   The data acquisition stage requires that you capture multiple scans of an object from all sides for full coverage. You don’t want the object to slide around the table while scanning. Any movements to the objects being scanned (and the turntable) during the 3D capture process will confuse the 3D scanner’s tracking and registration algorithms built into the 3D scanner. To help rotate the object with ease to get better quality scans, we like to use a manual turntable to rotate the object while scanning. It prevents the object from sliding or teetering while it is being scanned.

   

5. Tip #5: Scan With A Textured Background

   

   In 3D scanning, texture refers to the color photographs captured alongside the 3D geometry.

   Using a textured background is beneficial for tracking and registration during the 3D scanning process. A background with unique geometry or texture can improve the accuracy of the scan by providing reference points for the 3D scanner to track and align the scan data.

   

   Texture mapping is a complex topic, but it’s important to note that 2D images with text and color provide excellent background reference in the 3D scanning workflow. The same goes for unique 3D geometry in the background, it helps:

   • the 3D scanner track movement during data capture
   • the 3D scanning software align the scans into a 3D model during post-processing

   The background can be easily deleted during the post-processing stage.

   

   

6. Tip #6: Adjust Your 3D Scanning Software’s Settings to Match the Object

   

   Using incorrect 3D scanner settings can result in poor scan quality. To ensure good scans from your 3D scanner, it’s crucial to adjust the exposure and brightness settings based on the object’s lightness or darkness. By using the appropriate settings, you can achieve the best possible scan results from your 3D scanner. Because each 3D scanner model is different, you should read the software manual for your 3D scanner for more information on the settings.

   If you own an Artec 3D scanner, you can download the latest software manuals on our support site.

   

7. Tip #7: Recalibrate Your 3D Scanner for Accuracy

   A 3D scanner with poor calibration can result in inaccurate scan data.

   

   What is Calibration?

   Calibrating the 3D scanner helps maintain measurement accuracy and repeatability. Depending on the device, calibration may be performed by the user or the 3D scanner comes factory calibrated. It is a crucial process that allows the optical measurement instrument to determine its position, rotation, and behavior relative to the object being scanned.

   Mishandling or improper transportation, such as jolts or accidental drops, can cause a 3D scanner to lose its calibration and produce subpar results.

   To ensure accurate and high-quality scan data, it is recommended to recalibrate your 3D scanner periodically. The frequency of recalibration may vary depending on usage, but it is typically recommended to do so a few times a year. If you need to recalibrate the scanner yourself, be sure to follow the procedures carefully. You can also contact your vendor for guidance on how to achieve the most accurate scan results from the calibration process.

   

   

8. Tip #8: Training

   

   The user’s level of expertise is often underestimated as a critical factor affecting 3D scan quality. Even with the best equipment, insufficient training will limit its potential. To get the best capabilities out of your 3D scanner, it is recommended that you seek advice and guidance from your vendor or from a professional with relevant expertise. They use the equipment on a regular basis and can provide you with the expertise and tips on how to use a 3D scanner to its maximum potential. If you prefer self-guided learning, you can access online training through manuals, videos, and guides. It is crucial to allocate adequate time for training before commencing your first 3D scanning project.

   At GoMeasure3D, we offer professional training to all customers who purchase a scanner from us.

   Contact us if you need additional Artec technical support and training services.

Conclusion

The ability to get good scans will improve with practice and experience. You can learn a lot from mistakes, which will train you to become a 3D scanning expert.

It’s also important to remember that aside from preparation, the quality of the scanner will affect the quality of the scan data it produces. For example, professional 3D scanners using high-quality components and 3D scanning software that have undergone extensive R&D will produce better scan data quality compared to consumer-grade scanners. To learn more about this topic, please read our previous blog post related to how different types of 3D scanners affect scan quality.

While 3D scanners can scan most objects without a hitch, there are some surfaces that are more challenging to scan. These types of surfaces include dark, shiny, and transparent surfaces.

Why are these surfaces difficult to scan?

It’s due to how the 3D scanner interacts with these types of surfaces that causes a less than ideal scanning condition.

Ideal Condition for 3D Scanning

Optical light-based 3D scanners (i.e. laser, structured-light) use light as a projection source. Using a structured-light 3D scanner as an example, the system casts a series of patterns onto the object using the projection source. The pattern deforms as it hits the surface of the object. The scanner’s cameras capture images of these distorted patterns and use software’s algorithms to calculate the distance from the scanner to the object’s surface.

This is how the scanner derives 3D measurements in the form of point clouds. A point cloud is essentially a cluster of 3D coordinates (x, y, z) in space of an object’s surface. If you have millions of these points, you will produce a digital replica of the object.

Point Cloud

Why Do Dark, Shiny, or Clear Surfaces Interfere with the 3D Scanning Process?

While 3D scanners are great at capturing most surfaces, some types of surfaces cause the light to be distorted in such a way that it interferes with the data acquisition process. They affect how the 3D scanner views the object and consequently affect how it takes the images.

When scanning these challenging surfaces, it causes the following interference:

Surface Type	Dark	Shiny	Clear
What happens to the light?	The surface absorbs the light	Light scatters and bounces in uncontrollable directions	The light goes right through the surface
Examples	Black or dark parts	Metals such as chrome or steel, jewelry, mirrored surfaces, any reflective parts	Transparent surfaces such as glass or clear plastic

Tips for Overcoming the Challenge

1. Adjust your 3D scanner’s settings

   Some 3D scanners are pretty good at adapting to surface variations. Before you try other methods, see if your 3D scanner’s settings can be adjusted to scanning dark, shiny, or transparent parts.

   Each scanner will be different but usually adjusting the exposure settings helps to compensate for the object’s surface characteristics to create a better condition for scanning.

   Example: Artec 3D Scanners

   

   Using the Artec 3D scanner as an example, taking simple actions such as increasing the scanner’s sensitivity and slightly decreasing the brightness helped with scanning this black robe.

   To increase the 3D scanner’s sensitivity settings:

   • Artec Eva: the sensitivity is adjusted automatically
   • Artec Spider/Space Spider: Use the applicable slider in the main scan panel “Advanced” settings

2. Adjusting The Scanner’s Position In Relation To the Object

   Sometimes doing slight adjustments in the way you scan an object can have a big impact on your results. When scanning shiny surfaces, scan at a slight angle and distance. Light then diffuses instead of bouncing directly back into the 3D scanner which is the source of the problem.

   Normal Situations

   

   In normal conditions, you would position the 3D scanner perpendicular to the object to get the best scans.

   3D Scanning Shiny Parts

   

   For 3D scanning shiny objects, you would sweep around the object at a slight angle. You should experiment and see what is the best position for different types of surfaces.

   Technological Advancements

   3D scanners are getting better and better at 3D scanning challenging surfaces as technology becomes more sophisticated over time. With the Artec Leo, we scanned the tailgate of a black truck outdoors without any issues.

   We can capture even metal parts using the Artec Space Spider without any special treatment.

   However, if you want to scan holes or tight corners with better and cleaner scan results (as light bounces around these features) or if you have an extremely shiny part to scan, we would recommend using a developer spray to prepare the part to get the best results (which is discussed further in the next section).

3. Prepare the Part Using a 3D Scanning Spray

   

   There are some extreme cases (especially clear surfaces) when your 3D scanner is unable to scan properly even when you have the most ideal scanner settings. In those cases, you will need to spray the part with a matte opaque coating to cover the surface. The challenging surface is covered so it doesn’t cause issues during scanning and it creates the ideal 3D scanning surface.

   As you can see from the example of 3D scanning a motorcycle helmet, using a developer spray (also known as 3D scanning spray) drastically improves results.

   

   At our lab, we currently use AESUB 3D scanning spray to coat parts for 3D scanning specifically developed by 3D scanning experts. It’s simple, effective, and easy to use. Health is important to us. AESUB 3D scanning sprays are less toxic compared to similar sprays in the market. All our AESUB products are free of harmful titanium dioxide. AESUB Blue is free of pigments while AESUB White is pigment-based but is FREE of titanium dioxide nanoparticles (TiO2).

   See How It Works

   There are two types of 3D scanning sprays. They both are powdered aerosol spray that coats a very thin film but the vanishing spray is more convenient because there’s no messy cleanup. Actually, there’s no cleanup at all.

   Vanishing 3D scanning spray is especially ideal for delicate objects that can’t be cleaned after your project is complete. It disappears without a trace into the air usually within hours depending on environmental conditions.

   3D scanning spray which can be wiped off after the part is scanned with a cloth. It’s ideal for 3D scanning projects that take more than a few hours to days. It’s also more economical option compared to the vanishing spray.

   How Does Using 3D Scanning Spray Impact Scan Accuracy?

   You don’t have to worry about adding too many layers to the part as that can cause distortion to the accuracy of the 3D scans, especially when you are using the scan data for inspection or reverse engineering applications. We did an analysis of adding a 3D scanning spray coating and we did a video to report the results.

   

   Tips when using the spray:

   • Spray on an even, thin, uniform layer throughout the part. If you have a heavy thick coating it will influence the accuracy of the 3D scans.
   • To minimize the particles in indoor space, you can spray the part in a spray booth or outdoors.

Everything You Need To Know About Decimating 3D Scan Data [With Video Demo]

Decimating 3D scan data simply means you are making your file size smaller by reducing the number of polygons in your 3D mesh.

A 3D scan mesh can output into an enormous file size (sometimes up to 1 GB!) during the 3D scanning process. Doing this extra step helps reduce the amount of excess and redundancy that is not needed.

For best performance and efficiency, reduce the number of polygons by decimating the data. If done properly, you can maintain relatively good accuracy and resolution compared to the original file, without compromising on quality.

---

Why Decimating 3D Mesh Helps With Optimization

You are managing the file size for faster processing. The goal is to reduce polygon count without sacrificing on the detail. When using the scan file for downstream applications, decimating your scan file can help you work faster and easier.

For example:

• It’s easier to upload to websites like Sketchfab since a smaller file size means a faster upload. In addition, your account usually has a limit to the file size limit per upload. In the Sketchfab Pro account, there is a restriction of 200 MB file size limit per upload.
• Your 3D printer might not need that high of a resolution for printing. Having a smaller file size means less processing time and it makes it less complicated for the 3D printer to print your object. You are also less likely to get errors during the printing process.
• For reverse engineering, your computer might not be great at dealing with a large file, especially if you have an older computer. This can lead to lags and freezing to cause a lot of troubles when trying to get work done. Decimating your data will help the performance of your computer.

In addition, as 3D scanners are becoming more affordable and accessible, a vast amount of 3D data files get accumulated in your organization. Decimating your 3D scan data is one way to handle data management.

How Do You Decimate 3D Scan Data?

Here are two video demonstrations of decimating your 3D meshes inside Geomagic Wrap.

Takeaway

As you can see, decimation is similar to why you want to compress a file on your computer in order to save space in order to remove unnecessary and excessive weight. However, with decimating 3D scan data you have more control as to where and how you want to do it—all the while keeping the structural integrity of the 3D mesh (shape and detail) intact.
