Perhaps the most exciting aspect of the additive manufacturing industry is its scalability. With the capability to manufacture a part pretty much on-demand, 3D printing certainly has the potential to alter the way that manufacturers not only create their products, but also how they manage their supply chains, purchase raw materials, and allocate engineering resources. With an efficient, streamlined workflow enabled by additive manufacturing, companies can save significant amounts of time and money, and scale their operations at a pace they’d perhaps never before thought tangible.
With the knowledge that the concept of scalability is integral to enabling fully automated workflows, PostProcess set out to create an automated resin removal solution to accommodate high-volume stereolithography (SLA) production. Though PostProcess has developed multiple existing solutions for hands-free resin removal, this solution, called the DEMI 4000™, is our largest automated resin removal solution to date. The solution is specifically aligned for SLA print technologies and allows operations to handle high-volume operations with either large-sized parts or large builds with smaller-sized parts. Let’s walk through five of the features that make the UL/CSA listed and CE compliant DEMI 4000 a revolutionary innovation for the additive realm.
1. Patented SVC Technology
Submersed Vortex Cavitation (SVC) is the same type of technology used in several of PostProcess’s other automated solutions for SLA, DLP, and CLIP print technologies. Controlled by the AUTOMAT3D® software platform (more on that soon), SVC optimizes the rate of resin removal with advanced ultrasonics, a vortex pumping scheme, as well as heat and fluid flow.
2. AUTOMAT3D Software
With a user-friendly interface, the AUTOMAT3D software takes the guesswork out of post-printing with pre-programmed recipe formulations. Hosted on a multi-touch HMI interface, the software works to control the agitation intensities, temperatures, process times, and more to produce consistent end part finishings with no breakage. Rather than dealing with trial and error, operators spend less time on post-printing, and simply have to “press play and walk away.”
3. Large Processing Tank
Measuring 890mm x 890mm x 635mm, the DEMI 4000’s tank is able to handle large or heavy loads of parts at one time, effectively increasing throughput and reducing cycle times. The DEMI 4000 functions to align with the following printers:
3DS ProX 800
Max build envelope:
25.6” x 29.5” x 21.6” (650mm x 750mm x 550mm)
RPS NEO800
Max build envelope: 31.5” x 31.5” x 23.6” (800mm x 800mm x 600mm)
SSYS V650
Max build envelope: 20” x 20” x 23” (508mm x 508mm x 584mm)
4. Powered Lift System
The DEMI 4000’s ergonomic powered lift system allows for automatic lowering and heightening of tray loads. The automated adjustable rack system allows users to simultaneously process multiple build trays of various heights and widths. In addition to being convenient, the fully enclosed envelope helps ensure operator safety, as well as a clean work environment. The system itself integrates with the machine’s SVC technology for optimal ease of use.
5. Additive Formulated Chemistry
PostProcess’s detergents for resin removal are specifically developed for additive post-printing, unlike other common chemicals. Each detergent is uniquely optimized for different types of resins, including for specialized applications such as ceramic-filled resins and high-temp resins.
Our latest generation of detergent was found to have better longevity than all typical solvents (e.g. IPA, TPM, DPM), equating to more infrequent chemical change-outs, improved environmental-friendliness, and therefore a safer workplace environment. Having a flashpoint over 200°F / 93°C, this detergent complies with regulatory requirements.
Thanks to this unique blend of software, hardware, and chemistry, the DEMI 4000 is adept at consistently finishing parts with complex geometries and intricate internal channels. You can learn more about what the DEMI 4000 has to offer in an upcoming live tour here.
