3Dresyn USF Bio D, Ultra Safe & Fast bio based monomer free resin with 50% Bio content

Product description

3Dresyn USF Bio D is an ultra safe, ultra fast bio-based “monomer free” photopolymer formulation designed for high-speed proof-of-concept and model fabrication in SLA, DLP and LCD 3D printing workflows. The material is engineered to enable very fast layer curing while maintaining good definition and dimensional stability.

This formulation incorporates bio-based components derived from renewable sources, including soya-based constituents, and is optimized for rapid iteration workflows where speed, safety and cost efficiency are critical.
