PostProcess Technologies has once again revolutionized resin removal for additive manufacturing. Leveraging proven submersion technology, the DEMI 4000™ is the world’s only large scale software-driven 3D post-printing solution for high-volume stereolithography (SLA) production. Read on to learn what sets it apart.

Powered Lift System (Key Benefits – Safety and Ease of Use)

The DEMI 4000’s powered lift system allows for automatic lowering and heightening of tray loads. This ergonomic feature saves floor space and messy bath transfers by eliminating the need for multiple machines, and allows for same-height loading of multiple build trays and consistent, operator-free processing.

Large Processing Tank (Key Benefits – High Volume Production)

Measuring 890mm x 890mm x 635mm, the DEMI 4000’s tank is designed to hold 275 gallons of resin removal chemistry. At this size, the tank can handle heavy loads 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 and manages the work environment to control fumes and contain resin and detergent.

AUTOMAT3D™ Software Control (Key Benefits – High Volume Production)

AUTOMAT3D™ software takes the guesswork out of post-printing and reduces operator labor time with pre-programmed recipes. The software controls the agitation intensities, temperatures, process times, and more to deliver consistently complete resin removal. AUTOMAT3D optimizes the rate of resin removal with advanced ultrasonics, an advanced  pumping scheme, as well as heat and variable fluid flow. The system was designed with optimal operator ergonomics including multi-touch HMI with glass screen and stainless steel wash-down control buttons and interface panel.

Additive Formulated Chemistry (Key Benefits – Longevity, Cycle Times)

PostProcess offers a comprehensive suite of detergents, each uniquely optimized for post-processing 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.

Printer Alignment

For reference, the DEMI 4000 aligns with the following large SLA printers:

  • 3DS ProX 800
    • Max build envelope: 6” x 29.5” x 21.6”  (650mm x 750mm x 550mm)
  • RPS NEO800
    • Max build envelope: 5” x 31.5” x 23.6” (800mm x 800mm x 600mm)
  • SSYS V650
    • Max build envelope: 20” x 20” x 23” (508mm x 508mm x 584mm)
