3Dresyn USF Bio D Monomer-Free Fast Bio-Based Resin (50% Bio)

3Dresyn USF Bio D is an 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 and cost efficiency are critical.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within professional, educational and laboratory environments for fast prototyping, conceptual design validation and model fabrication.
