CREALITY Cr-Scan Otter 3d Scanner User Guide
01. Product Introduction
CR-Scan Otter is a high-precision, handheld, all-in-one 3D scanner compatible with scanning small, medium, and large objects. With a maximum accuracy of 0.02mm. From small screws to human bodies and large automotive components (10-2,000 mm’), it can effortlessly scan objects of various sizes. The ability to adapt to objects of various sizes is achieved by its innovative four-eye stereoscopic vision design. This includes a set of large focal length binoculars and a set of short focus length binoculars. The former is used to capture the details of small and medium objects at close range; the latter has a larger FOV and is used to scan relatively large objects, to ensure stable tracking with minimal loss.
This scanner is equipped with a depth computing specialized chip independently developed by us, which ensures smooth scanning with a maximum frame rate of up to 20fps. Using unique single-frame 3D imaging technology, it has excellent anti-shake performance. Advanced DOE structured light projection technology enables 3D scanning even outdoors(:,; 30,000 lux). With professional-grade texture supplemental light, it can smoothly complete full-color scans even in low-light environments, and give objects exquisite and realistic textures.
The all-metal body provides excellent heat dissipation, with a fanless design ensuring noise-free operation. Equipped with touch buttons, interactive indicator lights, and audible buttons, it makes operation more convenient and effortless.
Since the 3D scanner is a high-precision device, please handle it with care and store it properly. Avoid collisions or drops to prevent a decrease in accuracy or damage.

08. FAQs
• How to achieve better model details?
- Adjust the exposure time of the IR camera during scanning to ensure moderate exposure. Overexposure is shown as red, while underexposure is shown as blue.
- Try to maintain the optimal scanning distance. Generally, the closer the scanner is to the object without losing tracking, the better the details.
- During point cloud optimization, use a smaller point distance: For example, when the object size is small, the point distance can be set to 0.1mm.
- When meshing, ensure that the number of model faces is sufficiently large.

• How to scan the bottom of an object?
- Creality Scan provides a multi-project merging feature, allowing you to obtain the complete model of an object through different orientation and merge togethe?
- Scan the visible part of the object first to obtain a partial model, pause the scan, then change the object’s orientation, and continue tracking the previously scanned part to get the complete model.
When do you need to use a scanning pad?
When scanning smaller objects (such as wireless earbuds, medals, etc.), you can randomly place 3mm diameter marker points on the scanning pad and select the marker point mode for scanning.
• When do you need to use the USB 2.0 power cable?
When the computer cannot connect to the scanner due to an insufficient power supply, you can use this charging cable to connect an external charger to power the scanner.
When the scanner is connected to a computer’s USB 3.0 port and has sufficient power supply without using a docking station, you generally do not need to connect an additional power cable.
• When do you need to use the marker point mode or texture mode?
When the geometric features on the surface of the object are not prominent, you can apply the reflective marker points included in the package to the object and use the marker point mode for scanning. When the surface of the object has rich textures, you can directly use the texture mode for scanning.
• When is calibration necessary?
Calibration is necessary when the device has not been used for a long time (such as 3 months), or when the device has been accidentally bumped.
Note: The 3D scanner is a high-precision device, please handle it with care, and avoid collisions or drops to prevent damage or degradation to accuracy.
• Can calibration cards be swapped for each other?
Each calibration card is unique and corresponds to each scanne? They cannot be swapped. When using a calibration board for the first time, it needs to be scanned once to bind to the scanner using the QR code on the back. Otherwise, it may affect calibration accuracy .
• What should be noted when storing calibration boards?
After each use, please carefully store the calibration card to its original box for proper storage. Avoid contamination, scratching, or heavy pressure on the calibration card to prevent loss or damage.
• How to perform calibration?
Connect the scanner to the computer, open the Creality Scan software, go to the [Device] interface, click on [Calibration], and perform calibration by following the animated instructions.
09. Troubleshooting
- The Win system computer cannot connect to the scanner;
If using a desktop computer, it is recommended to connect to the USB 3.0 port on the back of the main unit (USB 3.0 and above ports are usually blue or red);
Confirm that the system used is Windows 10/11 64-bit;
The full installation paths for the scanner software Creality Scan must be in English. - What to do if the preview is not visible in the application on the Win system;
Use the provided charging cable to connect to a charger to ensure a normal power supply for the scanner;
Open the Windows Device Manager and check if there is a “CR-Scan Otter … ” related camera under “Cameras”;
Open Windows Settings-Privacy-Camera, confirm whether the system camera permission is turned on, and ensure that desktop applications have permission to access the camera. - What to do if the preview is not visible in the application on the Mac system?
Use the provided charging cable to connect to a charger to ensure a normal power supply for the scanner;
Update the scanner to the latest firmware;
Use a standalone adapter (the scanner comes with a USB-A to USB-C adapter), and avoid using multifunctional USB adapters whenever possible;
Install Creality Scan directly in the computer’s Applications directory. Avoid installation within subdirectories of the Applications directory. - How to deal with USB 3.0 interface being recognized as USB 2.0 in the Windows system?
You can try quickly reinserting the USB cable or first connect the USB 3.0 interface and then connect the scanner’s USB-C interface.
