PostProcess Technologies Inc., a global provider of automated and intelligent post-printing solutions for industrial 3D printing, has unveiled the DEMI 4000, the largest solution in their lineup of automated, intelligent post-printing solutions for additive manufacturing (AM) resin removal. The new DEMI 4000 leverages PostProcess’s submersible technology for consistent, hands-free resin removal on large part sizes or large builds with many smaller-sized stereolithography (SLA) parts. This solution addresses the growing market demand for a production-ready, software-driven finishing solution for high-volume SLA with the same fast cycle times, exceptional chemistry longevity, and safety features available in PostProcess’s existing lineup.
Enabled by PostProcess’s AUTOMAT3D software platform, the DEMI 4000 leverages patented Submersed Vortex Cavitation (SVC) technology. This technology uses advanced ultrasonics, a vortex pumping scheme, and heat and variable fluid flow in concert with proprietary additive formulated chemistry to optimize resin removal. With a user-friendly software interface, operators will be able to use pre-programmed recipes as well as create custom recipes to produce consistent end parts.
The comprehensive suite of chemistries offered with the system, each uniquely optimized for different types of resins including specialized applications such as ceramic-filled resins and high-temp resins, offer unparalleled saturation longevity and useful life compared to any other chemistry on the market. PostProcess’s recently launched PLM-403 specifically offers six times the longevity of commonly-used IPA, 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 allows users to simultaneously process multiple build trays of various heights and widths for optimal ease of use. This lift system in a fully-enclosed process volume provides an optimized operator experience while enabling a cleaner and safer working environment. The process envelope of the DEMI 4000 is aligned with many of the most popular production level SLA 3D printers, including the 3D Systems ProX 800, RPS NEO800, and Stratasys V650.
