DEMI 800™ 

Scalable Production with Safer, Faster & Sustainable Resin Removal

How to post-process 3D prints with DEMI 800™ Series machine, a PostProcess® proprietary patented Submersed Vortex Cavitation technology for revolutionary post-printing efficiencies? Learn more about DEMI's software, hardware, and chemistry features for optimal resin and support removal. PostProcess’ SVC technology utilizes agitated flow to effectively remove PolyJet and FDM 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.

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.

Automated Additive Manufacturing Post-Print Solution.

PostProcess® DEMI 800™ Series automated submersion systems are engineered to meet the demands of volume production while ensuring consistency of every part. All models incorporate a PostProcess proprietary software program and additive-formulated detergents for a complete additive manufacturing post-print solution.

Efficiency. Repeatability & Scalability

  • For resin removal, PostProcess comprehensive software, hardware, and chemistry system is proven to reduce post-processing steps by 50% or greater. It is the fastest resin removal system on the market and consistently cleans full trays in under 10 minutes. You can avoid the post-printing bottleneck, enable high-volume production and decrease the overall cycle time for the print operation.
  • Exceptional Detergent Longevity
    PostProcess’s detergent longevity offers high resin capacity, which means less downtime for detergent changeouts and reduced waste generation and disposal frequency, thus saving you time and money. This longevity beats IPA solutions by cleaning 5X as many parts before reaching saturation.
  • Minimized Chemical Hazards
    PostProcess proprietary formulation offers low volatility and low odour. The user-friendly solvents ensure a safer work environment compared to common solvent IPA, with much lower vapour pressure and higher flashpoint and no requirement for an explosion-proof environment.
  • Reduced Waste & Disposal Costs
    PostProcess’s Resin Removal detergent is part of a complete automated system that can deliver up to 75% savings in annual detergent disposal costs for IPA users.

DEMI 800. Innovative Technology. Smart Features.

The DEMI’s precise temperature control with one-degree increments eliminates thermal runaway for fast finishing without part warpage. Diagnostics and process monitoring react to key process parameters, reducing hands-on finishing time. The proprietary SVC technology intelligently combines ultrasonics, heat and fluid flow for unparalleled results and is designed with innovative vortex flow technology to ensure even distribution of mechanical energy. The system optimizes ultrasonic output by managing variable ultrasonic power throughout the cycle precision. Controlled mechanical and chemical agitation accelerates the removal rate with gentle action for fragile materials and fine feature details designed for use with patent-pending detergents optimized for additive materials.

The DEMI’s three-stage filtration extends detergent life for increased throughput, and no manual mixing of detergent means less maintenance and more machine uptime.
