FAQs
Q:
Do the blue laser parallel lines and single line of MT Gen2 support hybrid alignment?
A:

 Yes, it supports hybrid alignment for crossed lines, parallel lines and single lines. You can also switch freely during scanning to adapt to different scanning scenarios.

Q:
What upgrades and optimizations does MT Gen2 have compared with the previous MT model?
A:

 It adds a single-line scanning mode for better acquisition results in hard-to-scan areas such as deep holes and dead corners. It is upgraded with 7 blue parallel laser lines, achieving the resolution of 0.05mm, with an overall improvement in high-precision detail scanning capability.

Q:
What are the optimal scanning distances for different light sources of MT Gen2?
A:

The optimal scanning distances for each light source of MT Gen2 are as follows: blue crossed lines 250~300mm, blue parallel lines 210~260mm, blue single line 250~300mm, and infrared structured light 250~400mm. Scanning within this range delivers the best detail and accuracy.

Q:
In the 3DeVOK software, when aiming the scanner at an object, no point cloud is generated. The laser lines appear very weak, yet the device functions normally and calibration has been performed. What is the cause and how can it be resolved?
A:

This issue is typically caused by the surface material or color of the scanned object. Black, dark-colored, or highly reflective objects (such as metal or mirrors) absorb or reflect the laser abnormally, causing the laser lines to appear weak or difficult for the camera to recognize, thus preventing point cloud generation.

 

Solutions:

 

Increase laser brightness: Appropriately raise the laser intensity or gain in the software to enhance the visibility of the laser lines.

Use a developing agent (scanning spray): Evenly spray a developing agent (such as matte developing spray, talcum powder, or dedicated scanning spray) onto the object's surface. This will significantly improve laser reflection. Be careful not to apply too thick a coating, as it may obscure fine details.

If the above methods do not work, check whether the scanning environment has strong ambient light interference (e.g., sunlight, intense lighting). Try scanning in a darker environment.

Note: The developing agent is a temporary coating. After scanning, it can usually be removed with a soft cloth or water (refer to the product instructions for details).

 

Q:
When scanning with the 3DeVOK software, data layering errors (such as interlayer misalignment or displacement) occur. How should this be handled?
A:

You may choose one of the following two options depending on the data condition:

 

Option 1: Retract Frame (suitable for minor layering errors discovered during real-time scanning)

 

In the scanning interface, click the "Retract Frame" button, select the number of frames to retract, and undo the current frame data that caused the layering error.

 

Note: The retraction operation is irreversible. Retracted data cannot be restored. Please confirm that the frame data is no longer needed before proceeding.

 

Option 2: Point Cloud Pre-Processing Repair (suitable for overall repair after scanning is completed)

 

Click the "Finish Scan" button in the interface to end the current scan, then locate the "Optimize Floating Layering" function. Adjust the "Repair Extent" parameter (higher values provide stronger repair but may alter local details), and the software will automatically repair the layering error.

 

Suggestion: If the layering error is small and you are still scanning, prefer Option 1. If the layering error has formed a large area or the scan has already ended, use Option 2. If layering errors occur frequently, please check device calibration, environmental vibration, or hardware connections.

 

 

 

Q:
When using the 3DeVOK software for scanning, the computer runs very slowly or even crashes. How can this be resolved?
A:

 Please follow the steps below to troubleshoot:

 

Open Task Manager (shortcut: Ctrl + Shift + Esc), go to the "Performance" tab, and check whether the GPU memory usage is close to or has reached 100%.

If GPU memory usage is too high, close other GPU-intensive programs (such as large games, design software, video players, etc.), then retry scanning.

If the issue persists after closing unrelated programs, the current computer's hardware performance (especially GPU memory) may be insufficient. It is recommended to use a computer with higher specifications or upgrade the graphics card.

For further assistance, please contact 3DeVOK technical support with your specific hardware configuration information.

Q:
What is the purpose of saving project files?
A:

After scanning, you can save scan project files, point cloud project files, and mesh project files for data archiving to prevent data loss and facilitate further processing later.

Saving a scan project file allows you to recalculate starting from the real-time scanning stage; saving a point cloud project file enables you to regenerate the mesh from the point cloud stage; saving a mesh project file lets you reapply texture directly from the mesh stage.

Q:
When using a 3DeVOK series scanner with the wireless Airgo for scanning, after powering on by long-pressing the power button, the power indicator light turns on, and the scanner's touchscreen startup icon lights up. However, the middle indicator light does not illuminate, and the scanner automatical
A:

 It is most likely due to a loose power connection. Please check if the two power interfaces marked in the figure are securely connected. If there is a lanyard, lift the lanyard upward, then firmly insert the cable, tighten the screws, and ensure that both ends of the cable are not loose. Then try powering on again.

Q:

A:

Find the "Texturing Mesh" module in the lower process bar and click "Apply".

Check the **SeamEditor ** option in the texture settings panel to preserve the previous editing results.

Q:
How to check the CUDA version of the graphics card? What are the CUDA version requirements for the 3DeVOK Studio software?
A:

You can run the tool CUDA-Z to detect the CUDA version of your graphics card.

The minimum CUDA version required by the software is 7.5. As long as the detected version is ≥7.5, you can use it normally.

Q:
After installing the software, the error "3DeVOK Studio.exe - Corrupted Image" appears. What is the cause?
A:

This error usually occurs because Kernel-mode Hardware-enforced Stack Protection or Reputation-based protection is enabled on your computer, causing the system to block or misjudge the program files.

Solution:

-Open Windows Security.

-Disable the following settings:

-Firewall & network protection

-App & browser control (including Reputation-based protection, Kernel isolation, and related security options)

-Restart the software after disabling Smart App Control

A:

 In the 3DeVOK Studio softwareOn the top right corner of the software, click the "Configuration" icon - Preferences - Language

 

Q:
During the scanning process with the 3DeVOK scanner, tracking may sometimes be lost. What could be the possible reasons, and how to quickly find alignment?
A:

1.Insufficient tracking features
When the surface of the object is too smooth, contains many repetitive structures, or lacks distinct features, the system may be unable to stably recognize its current position, resulting in tracking lost.

Recommended Actions:

Improve tracking features Add markers or texture stickers
Adjust the scanning angle to increase feature overlap
Adjust the scanning parameters

2.Discontinuous scanning path
If the scanner is moved too quickly, changes direction abruptly, or lacks sufficient overlap between scanned areas, the software may fail to properly align and stitch the data.

Recommended Actions:

Maintain a steady and consistent movement speed

Ensure sufficient overlap between adjacent scanning areas

Avoid rapid, jump-like scanning movements

3.Surface material impact
Highly reflective, transparent, or dark materials may cause missing data or noise.

Recommended Actions:

Apply a removable scanning spray Adjust laser brightness parameters

Adjust the scanning parameters

4.Environmental interference
Strong ambient light, vibration, or improper device calibration may all affect scanning stability.

Recommended Actions:

Avoid strong direct light Maintain a stable scanning environment

Perform regular device calibration

Q:
When the graphics memory is insufficient, is it necessary to increase virtual memory? What is virtual memory used for?
A:

Virtual Memory is a mechanism in which the operating system allocates a portion of the hard drive or SSD storage space to temporarily store memory data when the physical memory (RAM) is insufficient.

Its core function is to extend the systems available memory capacity and prevent program errors or system crashes caused by insufficient physical memory.

When running programs consume more memory than the available physical RAM, the system transfers temporarily inactive memory data to a paging file, thereby freeing up RAM for currently active tasks.

It is important to note that increasing virtual memory does not improve computing speed, nor can it replace adding physical memory.

If the system frequently relies on virtual memory, it usually indicates that the physical memory is close to or has reached its limit. In such cases, disk read/write activity will increase, and overall performance may decline.

If performance bottlenecks persist over time, upgrading the physical memory capacity is strongly recommended.

 

Q:
Does the WIFI network card and router equipped with the Airgo support self-purchase and replacement? What are the requirements for the replacement models?
A:

The Airgo is recommended to be used with the officially suggested WIFI network card and router.
The recommended WIFI network card is the TP-Link Archer T3U, and the recommended router is the GL.iNet GL-MT3000.

If the above models are not available in your region, the selection of an alternative WIFI network card should primarily be based on driver-supported chips.
For example, chips such as RTL8812AU, RTL8822BU, and MT7921AU are compatible and can be used.

The mandatory requirement for replacing the router is that its transmission speed must be above 40 MB/s.
A gigabit router is recommended for better performance, but it is not a strict requirement.

Note: If users replace the WIFI network card and router on their own, the stability of data transmission cannot be guaranteed.

 

Q:
How to select only the mesh visible in the current view when processing a model in the 3DeVOK Studio scanning software?
A:

In the toolbar at the bottom of the software interface, the "Mesh Processing" button has the "Select Through Mesh" mode enabled by default. In this mode, box selection selects all mesh along the line of sight, including the back of the model. If you need to select only the mesh visible in the current view, please click the "Mesh Processing" button and switch the mode to "Select Visible Mesh". Taking the processing of hand dorsum data as an example, the actual effects of the two selection modes are shown in the figure.




Q:
What is the function of the "One-Click Edit" button in the 3DeVOK Studio scanning software?
A:

The "One-Click Edit" function button is located in the "Data Processing" module of the top toolbar. After scanning, click the "One-Click Edit" button and apply it to start one-click automated data generation, which includes point cloud processing, mesh generation, and texturing (if applicable).

 

Q:
In the 3DeVOK Studio scanning software, how to disable the "Preview" function?
A:

Locate the "Settings" button at the top of the software, click the drop-down menu, and enter the "Settings" page.


In the settings, turn off the "Preview" function.

 

Q:
What are the differences between handheld and desktop 3D scanners? What applications or scenarios is each type best suited for?
A:

Handheld 3D scanners are more flexible and are ideal for scanning complex or large objects, while desktop 3D scanners are more stable and better suited for small objects that require high-precision scanning.

Handheld 3D scanners, such as the 3DeVOK MT and MQ, are operated by the user holding the device during scanning. They offer high flexibility and are especially suitable for complex parts and on-site scanning scenarios where the object cannot be moved. They are widely used in artistic design, reverse engineering, 3D measurement, 3D visualization and display, 3D printing, scientific research, and education, etc.

Desktop 3D scanners use a fixed scanning system combined with an automatic turntable to complete the scanning process. They provide higher stability and are more suitable for high-accuracy scanning of small and precise parts. They are commonly used for quality inspection, product design, and artwork modeling, etc.

Q:
What is the resolution of the 3DeVOK MT scanner? Does the resolution affect the level of detail in the final 3D model?
A:

The MT offers three different light source modes: Blue Laser, Infrared Laser, and Infrared Structured Light . Each mode supports  different adjustable resolution.

Blue Laser: 0.05–5 mm (adjustable in 0.05 mm increments)

Infrared Laser: 0.1–5 mm (adjustable in 0.1 mm increments)

Infrared Structured Light: 0.1–5 mm (adjustable in 0.1 mm increments)

Different resolution settings will affect the level of detail in the final 3D model.
Generally speaking, a resolution of 0.2–0.3 mm is sufficient to capture enough detail for most applications. The smaller the resolution, the finer the details, but the point cloud processing time will also be longer.

Q:
How fast is the scanning speed of the 3DeVOK MT scanner? How long does it take to scan an object?
A:


The MT offers three different light source modes: Blue Laser, Infrared Laser, and Infrared Structured Light.
Each mode has a different point cloud acquisition speed:

  • Blue Laser: up to 3,300,000 points/sec
  • Infrared Laser: up to 2,450,000 points/sec
  • Infrared VCSEL Structured Light: up to 4,500,000 points/sec

The actual scanning time depends on the object size, selected light source mode, point spacing, scanning frame rate, and other settings.

Typical scanning time examples:

Scanning a human torso (spine area): approx. 1 minute
(Light source: Infrared Structured Light; Alignment : Geometry; Resolution: 1.0)

Scanning an artwork (20–30 cm): approx. 2 minutes
(Light source: Blue Laser; Alignment : Texture + Geometry; Resolution: 0.7)

Q:
Can the colored 3D model files (OBJ) obtained from 3D scanning be directly used for 3D printing?
A:

Yes, they can be used for printing, but you need to ensure the model is a closed, defect-free mesh.

 

For example, in Bambu Studio, follow these steps:

Click "File" in the top right corner → "Import," and select the corresponding OBJ file.

 

If the model has holes or defects after importing, use the 3DeVOK Studio software or Geomagic Wrap "Repair" and "Fill Holes" functions to fix the mesh, ensuring it is ready for printing. Consider support structures, printer size, material, and other limitations as well.

Q:
Why does the "Smart Surface" function in QUICKSURFACE sometimes create surfaces with holes?
A:

This is usually because the original mesh model is not fully closed (it contains holes or gaps). The "Smart Surface" function generates surfaces based on the mesh topology, and if the mesh has defects, the generated surface will also be incomplete.

Recommended Action: Before using "Smart Surface," use functions like "Fill Holes" or "Mesh Repair" to ensure the mesh is fully closed, which will avoid this issue.

Q:
In QUICKSURFACE, if I accidentally zoom or pan too far and lose sight of my object, how can I quickly bring it back into view?
A:
Simply right-click on any empty area in the viewport and select "Zoom to Fit" from the context menu. This will immediately center and resize the view to display all visible objects.


This will quickly reposition the object to the center of the view and adjust it to fit the display.

Q:
How can I use the "Manual Point Alignment" function in Absolute Orientation?
A:

Aligning corresponding points: The grid needs to be in the same viewport as the photo image. Use the ALT key to zoom in on a local area. Select corresponding points with the left mouse button. Press the space bar to switch between the grid and the photo. When there are at least 6 pairs of corresponding points, click {Align} - corresponding points alignment.

Q:
How do I choose a battery to extend the device’s operating time?
A:

For battery extension, this device is compatible with 21700 lithium batteries.

To ensure device safety, performance, and compatibility, we strongly recommend purchasing the official battery model through our authorized accessory channels.

Q:
What type of network cable should I use if the original one is damaged or lost?
A:

The device uses a Category 6 (Cat 6) Ethernet cable. For optimal performance, we recommend replacing it with an equivalent Cat 6 cable.

Q:
What should I do if calibration fails or severe data loss occurs with a new device?
A:

A:New devices are equipped with a transparent protective film on the lens surface. Please remove this film before use.

If issues persist after film removal, please contact technical support for further assistance.



 

Q:
Can damaged or stained scanning markers still be used?
A:

 It is not recommended to use damaged or stained markers. Any alteration to their shape or contrast can interfere with software recognition (e.g., in 3DeVOK Studio), potentially causing misalignment, failed marker detection, or errors in the final scan data.

Recommended Actions:

Best Practices:

Replace Promptly: If markers are visibly damaged or dirty, replace them with new, undamaged ones.

Store Carefully: Keep markers clean and properly stored before and after use to avoid contamination.

Apply Properly: Ensure markers lie flat without wrinkles or glare to maximize recognition accuracy

Q:
How to choose a turntable for use with a 3D scanner? Are there any specific size recommendations?
A:

Size Selection Criteria:

Core Principle: The diameter of the turntable should be significantly larger than the bottom size of the object being measured.

General Recommendations:

Small objects (e.g., parts, crafts): Recommended turntable diameter of 20-30 cm.

Medium objects (e.g., shoe boxes, helmets): Recommended turntable diameter of 40-60 cm.

For scanning large objects, consider a custom or professional large turntable.

Purchase Suggestions: When selecting a turntable, prioritize the product's load-bearing capacity and smooth rotation to ensure stability and smooth operation during scanning.

Q:
After opening the 3DeVOK Studio software, it can't import the EPJ file (EPJ is a scanning project file). How can I resolve this?
A:

Reason:

The device has not been connected, and the necessary KSET configuration file is missing.

 

Solution:

01.If there is a device available, simply connect the device, and the software will automatically activate and generate the configuration file.

02.If no device is available, you will need to manually import the KSET configuration file.

Follow these steps:

Copy the "KSET" folder from a USB drive / EPJ folder.

Right-click on the 3DeVOK Studio shortcut and select "Open file location."

Go to the software's root directory (D:\3DeVOK Studio\3DeVOK Studio).

Paste the "KSET" folder and ensure it contains the necessary configuration files

Restart the software, and you should be able to import the EPJ file successfully.

Q:
When using the 3DeVOK scanner with the wireless handle for scanning, what is the battery life?
A:

With the standard Nitecore NL2160 6000mAh batteries, two batteries provide approximately 2 hours of continuous operation.

Q:
When using a 3DeVOK scanner for scanning, how to distinguish between the concepts of accuracy, fineness, and detail?
A:

 

Accuracy refers to how close a measurement is to the true value, affecting the overall dimensional correctness of the model.

 

Detail (or fineness/resolution) describes the scanners ability to capture and distinguish small features on an objects surface, reflecting the level of intricacy in the model.

A scan with high detail can clearly show fine surface textures, scratches, and other small features.

  • Higher detail/resolution higher scanning resolution used.
  • Higher accuracy measurements are closer to the true dimensions.

 

Q:
In 3DeVOK Studio scanning software, how to create a background plane for removing desktop data in no marker mode (texture + geometry alignment)?
A:

Before starting the scan, go to "Scan Mode" > "More" > "Common" and enable the "Auto Background Plane" feature.

 

Before starting the scan, position the scanner at a 45-degree angle toward the object, ensuring it simultaneously captures both the object and the desktop surface. This allows the first frame to recognize both the object and the plane, facilitating automatic plane identification by the scanner.

 

Q:
What do the three parameters—"Memory," "Disk Space," and "VRAM"—at the bottom left of the 3DeVOK Studio scanning software represent?
A:

Memory: determines the computer's ability to run the scanner and process data. If insufficient, scanning fails: so expanding the virtual memory is necessary. Usage above 80% may cause software crashes: the project should be saved immediately.

Disk Space: defines data storage capacity. While it affects file saving, it is unrelated to operational speed.

Video Memory: governs real-time rendering and computing performance. If insufficient, issues such as display abnormalities, data loss, or crashes may arise. If usage exceeds 80%, the project should be saved immediately.

 

Q:
When scanning with marker mode in 3DeVOK Studio scanning software, insufficient markers cause poor alignment, and re-scanning is inconvenient:
A:

①Pause scanning and add markers to sparse areas.

②In the software, enable "Add Mark Points" under "Scan Mode" > "More" > "Common" before resuming.

*Note: New markers aid real-time alignment only and do not affect accuracy calculations. For precision, ensure sufficient markers are attached before scanning.

 

 

Q:
Why the scanner fails to recognize 3mm markers?
A:

If the scanner cannot recognize 3mm markers, it is usually because the option has not been enabled. Please follow these steps:  

- Click to enter the “More” settings menu in the software.  

- Under “Marker”setting, check whether “3mm Markers” is enabled.  

- If it is not enabled: Exit the settings, create a new scanning project, enable “3mm Markers” in the project settings, and then start scanning.  

- If it is already enabled but still not recognized: Ensure that the markers are firmly attached, the surface is clean and non-reflective, and retry under good lighting conditions.

Q:
By saving the color point cloud as an ASC file, what information can we obtain?
A:

When opening the ASC file with a text editor (e.g., Notepad), you can read three types of core data of the point cloud: three-dimensional spatial coordinates (x, y, z), normal vector parameters (i, j, k), and normalized color information (r, g, b).

Q:
In 3DeVOK Studio scanning software, what is the scan preview mode?
A:

The scan preview mode is a real-time calibration step before scanning begins. After clicking “Start Scan” for the first time, the software enters this mode. The interface displays a live view and distance bar, allowing you to adjust to the optimal scanning distance based on the device type (Infrared: 300–400 mm; Blue Light: 210–300 mm). Once the distance is properly adjusted, click “Start Scan” again to exit the preview mode and begin recording 3D data. This feature is enabled by default and effectively improves the success rate of initial scans, which can be disabled in the settings menu.
