Creality CR-Scan Otter test: 3D scanner with dual camera system for precise object detection

The new 3D scanner CR-Scan Otter by Creality impresses with an innovative four-lens system for object capture. The two dual-lens units—one with a long and the other with a short focal length—enable detailed captures of smaller objects as well as high-resolution scans of larger objects. We had the opportunity to test the device extensively.

The CR-Scan Otter comes in an attractive carrying case and is carefully packaged. The package includes the compact scanner, a power supply, a USB cable, a USB-to-USB-C adapter, a calibration disc, marker stickers, a hand and shoulder strap, a rubber mat, a test object, a cleaning cloth, and a manual.

The scanner is housed in a sturdy metal casing that conveys a high-quality impression and operates without active cooling. It is operated via three touch buttons that provide acoustic feedback. These buttons allow the user to start and stop the scanning process as well as adjust the sensitivity. A USB-C port connects the scanner to the computer, with power supplied via 5V/3A. A practical tripod thread is located on the bottom, hidden under a rubber plug.

Features

The CR-Scan Otter offers an impressive accuracy of up to 0.02 millimeters and achieves a scanning speed of up to 20 frames per second. The capture range covers miniature objects starting from 10 x 10 x 10 millimeters up to large items measuring 2 x 2 x 2 meters. The optimal working distance is between 110 and 1000 millimeters.

The system is equipped with two LED lights that enable precise 3D scanning even under poor lighting conditions. It utilizes structured infrared light as well as eight blue LEDs for marker recognition. The integrated one-shot 3D imaging technology effectively stabilizes the scanning process, improving tracking during the scan. The CR-Otter’s RGB camera captures colors and surfaces in 24-bit.

Thanks to this combination, the system shows particular strength when scanning challenging surfaces. Even black and metallic objects can be captured without additional coating. However, like all scanners of this technology, there are limitations with highly reflective or transparent objects, where scanning spray or talcum powder can be helpful. Diffuse ambient lighting also supports scan quality, while direct sunlight can impair it.

A special “Face & Body” function also facilitates scanning people and tolerates slight movements. According to the manufacturer, the infrared light used is safe for humans.

Technical Specifications in Detail

Software

The included CrealityScan software is compatible with both Windows and macOS and offers all the basic functions for controlling the scan process, processing point clouds, and model creation. A one-click process allows for quick results, and the software supports merging multiple scans, a marker mode, the face & body mode, and calibration functions.

The scanned models can be exported in OBJ, STL, and PLY formats, making them ideal for direct use in 3D printing. Creality plans to introduce additional accessories for mobile use on Android and iOS devices.

Conclusion

In practical testing, the scanner impressed with its high accuracy and speed, as well as its versatility in scanning both small and large objects. Even on slightly reflective and dark surfaces, the scanner delivered better results than previously tested models, and the tracking functioned surprisingly stably in our tests—though a steady hand and some practice are still beneficial. The texture recognition also proved reliable.

The software was easy to install, and the integrated basic functions worked flawlessly. However, the software could benefit from expanded editing options in the future. Until then, there is the option of further processing scanned objects with alternative software.

With a price of around 700 euros, the CR-Scan Otter positions itself in the mid-range price segment and offers a compelling balance of performance and cost. The combination of precise capture and user-friendly operation makes it an attractive choice—not only for makers but also for semi-professional users.

The scanner is available in the official shop.
