PostProcess DEMI Support and Resin Removal Solutions

Article by GoEngineer on Oct 22, 2021

Additive manufacturing has completely transformed the way businesses test, prototype, and produce products; from extra durable auto and aerospace applications to delicate medical models. But regardless of the industry you’re in, or the material technology you use, post-printing inefficiencies can still prohibit full scalability. The intelligent resin and support removal technologies available with PostProcess Technologies’ DEMI systems can help streamline your additive workflow. 

The DEMI line of post-printing machines are submersion systems utilizing the patented SVC (Submersed Vortex Cavitation) technology to automate the finishing of material extrusion, material jetting, and photopolymer 3D printed parts quickly and consistently. 

3D printers that use material jetting technology (e.g., Stratasys PolyJet) are often used to create detailed medical models, full-color concept modles, and other professional applications with high detail and delicate features. Traditional finishing methods may result in damage to the parts if not handled with extra care and precision. DEMI systems minimize operator errors and can reduce the amount of hands-on time required. 

PostProcess DEMI PolyJet Removal

3D Printers that use material extrusion methods (e.g., Stratasys FDM) often produce large parts or high quantities in a single print, but long post-printing cycles can limit throughput. By minimizing drying time and overall finishing time, PostProcess DEMI solutions boost your operation’s productivity for scalable production. 

For Photopolymer vat 3D printing (e.g., Stereolithography), part cleaning often involves the use of hazardous solvents like Isopropyl Alcohol (IPA), DPM, or TPM. The chemistry solutions developed for the DEMI systems are not only safer and easier to dispose of but are faster and more sustainable.

  • Machine footprint: 23.5” L x 18” W x 15.5” H
  • Weight: 35lbs
  • Detergent capacity: 5 gallons

DEMI 400

The DEMI 400’s small frame makes it easy to fit in any post-printing room. It can be used for the removal of PolyJet or FDM supports and excess resin for SLA, CLIP, DLP, and other resin-based technologies. Notable specifications include:

  • Envelope: 14” L x 14” W x 14” H
  • Machine Footprint: 29” L x 36” W x 43” H
  • Weight: 300 lbs
  • Detergent capacity: 17 gallons

DEMI 800

The DEMI 800’s large tank allows for the cleaning of multiple parts or large models. With their SVC technology, this system can remove PolyJet or FDM supports or excess resin for SLA, CLIP, and DLP. Notable specifications include:

  • Envelope: 18” L x 18” W x 18” H
  • Machine footprint: 34.75” L x 43.5” W x 59.75”H
  • Detergent capacity: 40 Gallons
  • Weight: 700 lbs

DEMI 910

The DEMI 910’s detergents were developed for specific Carbon resins and Carbon 3D printers. Notable specifications include:

  • Envelope: 18” L x 18” W x 18” H
  • Machine footprint: 34.75” L x 43.5” W x 59.75”H
  • Detergent capacity: 40 gallons
  • Weight: 750 lbs

DEMI 4000

The DEMI 4000 Series is the world’s only automated solution for production-scale resin removal built to process large photopolymer part sizes or builds. Notable specifications include:

  • Envelope: 35” L x 35” W x 35” H
  • Footprint: Footprint: 87” L x 50” W x 88” H
  • Detergent: 260 gallons
  • Weight: 2,590 lbs

All DEMI systems are equipped with recipe storage and recall for repeatable production making your post-printing as simple as press play and walk away.
