PostProcess Technologies  

Engineered specifically for SLA, DLP, and CLIP additive print technologies, the DEMI family of solutions replaces traditional manual resin removal techniques and hazardous solvents with an automated blend of proprietary software, hardware, and chemistry. Patented in 2020, the Submersed Vortex Cavitation (SVC) technology leveraged in each of these solutions ensures parts are uniformly and consistently exposed to detergent and cavitation during post-printing. This technology is also renowned for the safety and sustainability it enables, thanks to detergent with a high flashpoint that outlasts other solvents.

Launched in 2020, the DEMI 4000 is the world’s first production volume solution for automated SLA resin removal. The solution’s utilization of a powered lift system allows ergonomic loading of multiple build trays, eliminating the need for multiple machines. Developed just for Carbon® and the unique needs of the L1 and M2 build platforms, the DEMI 910 is also new to the DEMI family.

The DEMI 910 features a specialized fixture design, making it capable of seamlessly removing resin from a Carbon large-format L1 build platform, or two build platforms from a Carbon high-resolution M2 printer. Thanks to the ergonomic design of this machine, DLS printed parts can be processed without ever having to leave the build platform, improving productivity for Carbon users. 

Like every other PostProcess automated resin removal solution, the DEMI 910 utilizes patented Submersed Vortex Cavitation (SVC) technology, which employs an agitated flow to remove resin quickly and with uniform results. This solution integrates proprietary software programming and Carbon-specific formulated detergents, developed to be compatible with the most popular Carbon resins, including EPU 41, EPX 82, MPU 100, RPU 70, RPU 130, and UMA 90 and LOCTITE® 3D IND 405 Clear certified for Carbon printers. Overall, the process is safer and more sustainable than most traditional resin removal methods. 

Patented in 2020, Volumetric Velocity Dispersion (VVD) technology powers PostProcess’s automated and intelligent solutions for FDM support removal. The technology works in tandem with proprietary detergents and software to effectively remove support materials from 3D printed polymer parts with a high-volume, low-pressure spray method. This method employs a series of jet streams spraying bidirectionally, coupled with a perpendicular linear motion for mechanically assisted support removal, and functions to keep FDM part geometries intact with minimal damage. This automated technique improves post-printing efficiencies compared to highly manual finishing methods like dunk tanks, pliers, or picks. 

Both the DECI and BASE utilize VVD technology, and offer large print envelopes for high-volume throughput, with the BASE having the largest envelope in the PostProcess support removal series.

As the pioneering automated surface finishing solution, the RADOR employs PostProcess’s patent-pending Suspended Rotational Force (SRF) technology. To achieve the desired surface finish on each 3D printed polymer part, the RADOR encompasses optimized energy with vertical motion, combined with proprietary additive formulated abrasive media. During software-driven rotation, 3D printed parts are suspended in a mixture of media and detergent for an advanced and additive-specific abrasive surface finishing process.  Not only is this automated process much less laborious than hand sanding, but this automated process significantly reduces the risk of part damage. 

With the range of media shapes and sizes offered, users can address multiple materials in one batch for a one-size-fits-all approach.  Like every solution in PostProcess’s full line of surface finishing solutions, the RADOR was developed with noise-reducing features for low dBa to reduce production environment noise. 

While surface finishing additive parts already comes with an array of challenges, finishing 3D-printed metal parts requires tighter tolerances, support structure considerations, and sometimes even additional safety considerations. The RADOR and DECI Duo are both optimized to handle the delicate nature of additive manufactured parts. 

The RADOR employs PostProcess’s proprietary Suspended Rotational Force (SRF) technology, which encompasses optimized energy with vertical motion, combined with proprietary additive formulated abrasive media. During software-driven rotation, metal 3D printed parts are suspended in a mixture of media and detergent for an advanced and additive-specific abrasive surface finishing process.  

The DECI Duo leverages a different proprietary PostProcess technology, Thermal Atomized Fusillade (TAF) technology, in which two single-axis jet streams comprised of compressed air, detergent, and suspended solids blast parts as they rotate for maximum surface exposure.

PolyJet printing enables especially intricate and delicate part geometries, but traditionally employs very messy and cumbersome post-printing processes that are not optimized for additive parts. As a result, manually-reliant PolyJet finishing methods can lead to high breakage rates, and cause damage to PolyJet parts. 

The DEMI 200, DEMI 400 Series, and DEMI 800 Series by PostProcess Technologies are the pioneering automated post-printing solutions for PolyJet printing. Each solution implements PostProcess’s own Submersed Vortex Cavitation (SVC) technology, which was patented in 2020. Renowned for replacing the need for hazardous chemicals, the technology employs a blend of proprietary software, hardware, and chemistry to ensure parts are uniformly and consistently exposed to detergent and cavitation during post-printing. This technology is also renowned for the safety and sustainability it enables, thanks to detergent with a high flashpoint that outlasts comparable solvents.
