DEMI 800 Series – Support & Resin Removal

When throughput is essential, the PostProcess® DEMI 800™ Series automated submersion systems are engineered to meet the demands of volume production while ensuring consistency of every part. The varying specifications of our models ensure a range of features are available for your automated post-printing needs. All models incorporate our proprietary software program and additive formulated detergents for a complete additive manufacturing post-print solution.

The DEMI 800 Series uses our patented Submersed Vortex Cavitation (SVC) technology and removes PolyJet supports or excess resin. PostProcess’ SVC technology utilizes agitated flow to effectively remove supports with a ‘sink-float’ process to rotate parts throughout the chamber. This variable motion, combined with optimal energy delivery and detergent filtration, results in fast and uniform removal. With the motion of fluids within the machine controlled by our Agitation Algorithms, sensor data adjusts in real-time so that parts are not damaged and removal of supports and resin is consistent.

The DEMI 800 Series integrates a number of design features for ease of use and integration into your 3D printing operations, like noise reduction for a low dBa, a powerful magnetically driven pump, and advanced filters for extended detergent life. A fully insulated tank to keep the temperature consistent for energy efficiency, a basket to remove parts from the system and harness at the top of the unit, and ergonomically friendly tank orientation are just a few of the uniquely engineered features. The PostProcess DEMI 800 Series is available in a variety of models based on your unique application needs.
