PostProcess® DEMI 400™ Series


DEMI 400™ Series 

Safer, Simpler, Automated Cleaning of 3D-Printed Dental Parts & Medical Devices

DEMI 400 Series from PostProcess Technologies help you to further advance your additive manufacturing workflow. The DEMI leverages patented, software-driven Submersed Vortex Cavitation (SVC) technology and additive formulated chemistries to optimize support and resin removal processes. Benefits? From automation and less labour work, to higher quality of dental 3D-printed parts and overall cost savings, you can stay ahead of the competition.

Hands-Free Post-Printing without IPA

By adopting additive solutions, dental labs eliminate time-consuming traditional molding processes, transitioning to a digitized method for swiftly producing dental models, surgical guides, splints, mouth guards, dentures, and more.
While this technology accelerates custom model creation, traditional post-printing methods, such as isopropyl alcohol (IPA) baths, pose safety risks and may warp models, impeding workflow and efficiency scaling.
Discover how to overcome bottlenecks and be IPA-free!

Automated System

AUTOMAT3D®, the machine control, designs optimal cycle times for specific parts, controls temperature and agitation level.


Proprietary Agitation Algorithms

Post-Process Technologies' proprietary Agitation Algorithm controls the system’s energy, speed, and direction, ensuring your productivity is boosted by producing consistent end parts with no breakage.

Safer & Biocompatible Detergents

Works with safer detergent that is non flammable/non combustible. In addition, for hands-free operation, the automatic liftgate raises and lowers parts when cycles starts and ends.

Easy Installation

There's no need for drain or incoming water supply within the facility. Only power source is required to have the machine running.

Each innovative technology has its uniqueness. Are you wondering what solutions are best for your production needs?

The DEMI™ Advantage

Finish 8x as many parts as IPA!

PostProcess’ automated resin removal solutions finish eight to ten times* as many parts as IPA before reaching saturation, enabling higher throughput and more optimally finished medical parts. In addition, their proprietary resin removal detergents, e.g. PLM-403-SUB, have proven compliance with ISO standard 10933 for biocompatibility.

*Based on PostProcess estimates.

Premium Quality Prosthetics & Dental Medical Devices

Most support or resin excess removal solutions can damage delicate parts such as semi-permanent dental aligners. Thanks to the patented SVC technology and DEMI’s software intelligence, it ensures that 3D-printed parts are uniformly, consistently, and reliably exposed to detergent and cavitation as they undergo post-printing.

DEMI Technology with Dental Parts

AUTOMAT®. Intelligent Software Control

  • Get the desired finish every time at the touch of a button
  • Thanks to the software’s Agitation Algorithms with pre-programmed recipe formulations, you eliminate guesswork and errors, thus fewer scraped parts or inconsistent results.
  • The software varies agitation intensities, temperatures, process time and other process factors to deliver the ideal finished part.

Return of Investment (ROI)*

Cost Savings as a result of:

  • Disposal Cost Savings: PostProcess detergents are less hazardous than IPA, and cheaper to dispose of. Users can achieve over 75% or more savings in annual detergent disposal costs when replacing IPA with PostProcess® solution
  • Longer Detergent Lifespan: Up to 30% reduction in total yearly resin removal detergent costs.
  • Less Labour Work: Because the PostProcess solution is automated and extremely effective, the need for manual labour and hands-on technician time is virtually eliminated.
