DEMI 4000 Resin Removal Machine Features & Specification

Hybrid post process

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.

The 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.

Why you need a DEMI 4000 Resin 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 4000 Resin Removal machine can work on numerous printed parts simultaneously. Enabling companies to focus on higher-value activities.
