Post Process DEMI 4000™ Series

Resin Removal

Need a scalable post-printing solution for high-volume stereolithography (SLA) production?

The DEMI 4000™ Series is the world’s only automated technology developed for production SLA resin removal. Powered by our proprietary software platform, AUTOMAT3D®, this 3D solution utilizes our patented Submersed Vortex Cavitation (SVC) technology, ensuring consistency and optimizing the rate of resin removal.

The solution works in concert with PostProcess’s suite of long-lasting detergents, specialized for 3D applications from standard resins to ceramic-filled resins to high-temp resins. The most recent detergent release outperforms all typical solvents (e.g. IPA, TPM, DPM) on longevity, and offers an exceedingly safe flashpoint over 200°F / 93°C. This decreases the frequency of chemical changeouts and improves sustainability standards.

With a processing tank measuring 890mm x 890mm x 635mm, the DEMI 4000 Series can seamlessly process large part sizes or large builds with many smaller-sized parts, improving cycle times and increasing throughput. The utilization of a powered lift system eliminates the need for multiple machines, allowing ergonomic, operator-friendly same-height loading of multiple build trays.


The lift system’s fully-enclosed process envelope provides an optimized operator experience while enabling a cleaner and safer working environment. The process envelope of the DEMI 4000 is aligned with many of the most popular production level SLA 3D printers, including the 3D Systems ProX 800, RPS NEO800, and Stratasys V650.
