Support Material Removal

  • Submersible system for the shop floor, with an envelope size to handle small parts in high volumes and medium sized parts.
  • Patent-pending software, user-friendly hardware, and eco-friendly consumables works collectively to deliver exacting support removal while increasing the throughput of your production.
Hybrid post process

Software Driven

PostProcess has taken the guesswork out of post-printing by creating pre-programmed recipe formulations designed from data. Instead of trial and error resulting in scrapped parts or inconsistent results, you get the desired finish every time at the touch of a button.

Carefully controlling the system’s energy, speed, and direction, the Agitation Algorithm ensures your productivity is boosted by producing consistent end parts with no breakage. The software varies agitation intensities, temperatures, process time and other process factors to deliver the ideal finished part.

The PostProcess systems are enabled by a user-friendly interface powered by advanced industrial controllers from world-leader Beckhoff™, resulting in efficient use of your labour to drive volume production.

Paired with exclusive detergents, the right amount of time, and exact temperature based on the material and geometry of the 3D printed part, the DEMI 400 Support Removal solution delivers precise, hands-free support removal from 3D printed parts. Utilizing proprietary software, the machine combines multiple forms of customized agitation and optimized energy, and includes:

  • Variable temperature (70-156°F)
  • Programmable cycle time
  • Proprietary Agitation Algorithms

Innovative Technology

The DEMI 400 Support Removal system integrates multiple technologies. Agitated flow is essential to effectively remove supports and is done with a ‘sink-float’ process to rotate parts throughout the chamber. This variable motion, combined with optimal energy delivery, detergent filtration and a powerful pump delivering strong flow agitation, results in fast and uniform support removal.

Thoughtful Design

The DEMI 400 Support Removal integrates a number of features for ease of use and integration into your operations, like noise reducing features for a low dBa. A fully insulated tank to keep 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 unique PostProcess features.


All of the patent-pending engineered solutions have been developed for high-performance and optimized to use eco-friendly detergents and media. Detergents are available in pre-mixed 5 gallon and 55 gallon containers. Concentrated versions are also available.

Why you need a DEMI 400 Support Removal Machine

3 Advantages of using an automated Support Removal Solution for 3D printed parts

1. Consistent Results

PostProcess ensures that supports on every part are consistently and completely removed — no breakage and no missed supports. Reliability that each part will be identical all the time, every time.

2. Reduced Cleaning Time

Whether production is in the tens, the hundreds or the thousands, throughput is crucial. PostProcess reduces the cycle time for removing supports and eliminates the manual post-printing ‘bottleneck’.

3. Greater Productivity

The PostProcess DEMI 400 Support Removal machine can work on numerous printed parts simultaneously. Enabling companies to focus on higher-value activities.
