Scanning speed can reach 15 m/s.

The scanning speed of the RSPro 800 is impressively fast, reaching an incredible rate of 15 meters per second. This exceptional scanning speed significantly reduces the overall time required for scanning operations. With such a high-speed capability, projects can b e completed in a fraction of the time it would take with slower scanning systems.

Key components are of international top brands.

Our machine is equipped with key components sourced from internationally renowned top brands. The selection process for these components was meticulous, ensuring that only the highest quality and most reliable options were chosen. Among these esteemed brands are Panasonic from Japan, Optowave from America, and Scanlab from Germany.

Automatic control of surface level and processing parameters.

With the automatic surface level control, The RSPro 800 intelligently detects and adjusts the surface level of the material being processed. This eliminates the need for manual adjustments and minimizes the chances of errors or inconsistencies. By maintaining an optimal surface level throughout the printing or processing operation, we can achieve exceptional precision and accuracy, resulting in flawless end products.

Marble recoating platform frame

The use of a marble recoating platform frame provides significant advantages. Marble’s hardness and dimensional stability offer a solid foundation, minimizing vibrations and enabling precise layer deposition. This ensures impeccable surface quality. Additionally, the marble frame allows for an impressive layer thickness of 0.05 mm, delivering accurate reproduction of intricate details.

Closed loop control strategy for: Platform movement/Laser power/Resin level resin temperature/Negative pressure

This dynamic control mechanism continuously monitors and adjusts these parameters in real-time, ensuring precise and consistent performance throughout the printing process. By actively regulating platform movement, laser power, resin level, resin temperature, and negative pressure, our machine achieves exceptional accuracy, reliability, and quality in the final printed objects.

CE certification

By achieving CE certification, the RSPro 800 demonstrates its compliance with the stringent regulations and quality standards set forth by the EU, ensuring that it meets the necessary criteria for safe and reliable operation.


This machine provides a wide range of 3D printing capabilities: form and function prototyping and modeling, short-run injection molds, pattern creation, and investment casting.
