PostProcess’ Demi 4000 Optimizes Automated SLA Resin Removal

PostProcess Technologies’ Demi 4000 is an automated, intelligent post-printing solution for additive manufacturing (AM) resin removal. The Demi 4000 utilizes PostProcess’ submersible technology for consistent, hands-free resin removal on large part sizes or large builds with many smaller sized stereolithography (SLA) parts. This machine addresses the growing market demand for a production-ready, software-driven finishing solution for high-volume SLA with fast cycle times, exceptional chemistry longevity and safety features.

Enabled by PostProcess’s Automat3D software platform, the Demi 4000 employs Submersed Vortex Cavitation technology, which includes advanced ultrasonics, a vortex pumping scheme, and heat and variable fluid flow in concert with additive-formulated chemistry to optimize resin removal. With a user-friendly software interface, operators will be able to utilize preprogrammed recipes as well as create custom recipes to produce consistent end parts.

The company says the system comes with a comprehensive suite of chemistries which offer more saturation longevity and useful life compared to other chemistries. Each chemistry is uniquely optimized for different types of resins, including specialized applications such as ceramic-filled resins and high-temperature resins. This includes PostProcess’ PLM-403 which is said to provide six times the longevity of commonly used isopropyl alcohol, resulting in less frequent chemical changeouts, less machine downtime and safer working conditions using environmentally conscious constituent elements.

The Demi 4000’s innovative adjustable and ergonomic lift system enables users to simultaneously process multiple build trays of various heights and widths for optimal ease of use. This fully enclosed lift system provides an optimized operator experience while enabling a cleaner and safer working environment. The process envelope of the Demi 4000 is aligned with many popular production level SLA 3D printers, including the 3D Systems ProX 800, RPS NEO800 and Stratasys V650.
