DECI Rectangular Surface Finish

The patent-pending DECI Rectangular automated surface finish vibratory system is exclusively engineered for additive manufactured parts. Designed to meet the specifications for your desired Roughness Average (Ra) to achieve various types of finishes, the DECI Rectangular is ideal for all 3D printed materials, including FDM, SLS, SLA, CLIP, PolyJet, Ultem and more. No other post-print solution integrates hardware, software, and chemistry into a complete system that removes the post-print bottleneck to enable increased time to market.

PostProcess is singularly dedicated to post-print technologies for the additive manufacturing market. The result is a forward-thinking design that increases the efficiency of your 3D printing operations. The DECI Rectangular’s large working envelope can be divided to run both abrasive and polish operations simultaneously. Additionally, our proprietary and eco-friendly media and detergents are formulated specifically for additive materials.

Our AUTOMAT3D™ software, which controls our proprietary Agitation Algorithms, provides real-time decision making for your desired surface finish while preserving the fine-feature detail of unique geometries. Precisely controlling all variables, including heat, frequency, amplitude, and lubricity, our solution ensures less breakage. In addition, you have the capability to “set it and forget it” with recipe programming that no other system can offer.
