DEMI 4000 – PostProcess Technologies
The World’s First Full-Stack Solution for Production SLA Resin Removal
Need a scalable post-printing solution for high-volume stereolithography (SLA) production? The DEMI 4000™ is the world’s only automated technology developed for production SLA resin removal. Powered by our proprietary software platform, AUTOMAT3D®, this 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 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 and equipped to hold 275 gallons of resin removal chemistry, the DEMI 4000 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.

Your High-Volume Automated Solution
AUTOMAT3D takes the guesswork out of post-printing and reduces operator labor time with pre-programmed recipes. Controlling agitation intensities, temperatures, process times, and more, the DEMI 4000 delivers consistently complete resin removal. AUTOMAT3D optimizes the rate of resin removal with ultrasonics, an advanced pumping scheme, as well as heat and variable fluid flow.
Industry-Leading Cycle Times & Detergent Longevity
PostProcess offers a comprehensive suite of detergents, each uniquely optimized for post-printing of numerous resins from various manufacturers. This extends to specialized applications such as ceramic-filled resins and high-temp resins. Our newest generation of detergent was found to have better longevity than all typical solvents (e.g. IPA, TPM, DPM), and an exceedingly safe flashpoint over 200°F / 93°C. This equates to less frequent chemical change outs, improved environmental friendliness, and compliance with regulatory requirements.
Built for Productivity and Safety
Measuring 890mm x 890mm x 635mm, the DEMI 4000’s tank is designed to hold 275 gallons (1,040 liters) of resin removal chemistry. At this size, the tank can handle multiple trays of parts at one time, effectively increasing throughput and improving cycle times for all part sizes. Additionally, as a fully-enclosed system with a ventilation port, the DEMI 4000 ensures safety for operators, effectively controlling fumes while keeping resin and detergents contained.
