PostProcess DEMI X 520 Benefits


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.

Innovative Technology

The DEMI X 520 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 X 520 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.

Why you need a Support Removal Solution

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 X 520 can work on numerous printed parts simultaneously. Enabling companies to focus on higher-value activities.
