DEMI 4000

DEMI 4000

Scalable post-printing solution when you run high-volume stereolithography production.

Unparalleled Productivity of Postprocessing SLA parts

The DEMI 4000 Series is the world’s only automated technology developed for production SLA resin removal.  The 4000 Series works in concert with PostProcess’s suite of long-lasting detergents. This means you can use it for applications from standard resins to ceramic-filled resins to high-temp resins. 

With a processing tank measuring 890mm x 890mm x 635 mm, you 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.

Efficiency and High Quality

Powered by a proprietary software platform, AUTOMAT3D, the DEMI 4000 Series utilizes the patented Submersed Vortex Cavitation (SVC) technology. This ensures consistency and optimizes the rate of resin removal in your SLA printed parts.
