DEMI Support Removal

When throughput is essential, the DEMI Process automated submersion system is engineered to meet the demands of volume production while ensuring consistency of every part. The varying specifications of our four models ensure a range of features are available for your support removal needs. All four models incorporate our proprietary software program and eco-friendly detergents for a complete additive manufacturing post-print solution.

The patent-pending DEMI uses our unique Submersed Vortex Cavitation (SVC) technology and removes supports from the following 3D printing technologies: FDM, SLA, CLIP, Polyjet, and more.

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 support 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 is consistent.

The DEMI 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, 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.

PostProcess offers the DEMI in four models, based on your needs, including two types of agitation: single (flow); dual (flow and ultrasonics):

*DEMI Model 1: 110V, single agitation

*DEMI Model 2: 220V, single agitation

*DEMI Model 3: 110V, dual agitation (includes 1,750W ultrasonics)

*DEMI Model 4: 220V, dual agitation (includes 1,750W ultrasonics)
