PostProcess DEMI X 5000 accelerates resin removal for large-format SLA printing

Post-processing remains a bottleneck in many SLA workflows, especially when large-format parts come out of the printer. PostProcess Technologies is addressing this challenge with the new DEMI X 5000, an enhanced system for automated resin removal. It is based on the established DEMI 4100, but is explicitly designed for large SLA builds and is intended to clean parts in ten minutes or less – regardless of the standard resin class used.

The system combines an enclosed process volume with an automated lift and loading mechanism that accepts build platforms directly from large SLA printers. Adjustable support arms and spring-loaded grippers are designed to simplify handling, particularly for heavy trays. Inside, the DEMI X 5000 uses a dual-flow approach: variable-speed pumps generate vertical and horizontal flows that create a multi-vortex effect, loosening resin adhering even in undercuts and internal cavities. A tiltable carrier supports drainage of the process fluid on downward-facing surfaces, which is especially relevant for oversized parts.

Instead of conventional IPA baths, PostProcess relies on a proprietary, non-flammable chemistry. According to the company, this can reduce disposal costs by around 75 percent compared with isopropanol-based methods, while the fully encapsulated process chamber lowers vapor emissions into the surrounding environment.

“With the DEMI X 5000, we’ve taken everything our customers love about the DEMI 4100 automated resin removal solution and elevated it,” said Jeff Mize, CEO, PostProcess Technologies. “From faster cycle times and improved detergent flow to enhanced ergonomics and safety, this system enables manufacturers to achieve higher throughput and greater consistency while improving the safety and sustainability of their production facility.”

The system is controlled via the AUTOMAT3D platform, where process recipes can be stored, customized and retrieved with one touch. For operations processing SLA parts from prototypes through to small series, the DEMI X 5000 is aimed at reproducible results, reduced manual effort and better scalability of downstream process steps in 3D printing.
