3Dresyn Biotough D80 MF Monomer-Free Tough Semi-Rigid Biocompatible Resin

Product description

3Dresyn® Biotough D80 MF is a biocompatible, monomer-free photopolymer resin engineered to provide a balanced combination of rigidity and toughness, with improved resistance to impact, mechanical fatigue and crack propagation compared to more rigid grades.

The material is designed for professional additive manufacturing workflows requiring controlled mechanical behavior and dimensional stability.

Application framework

Intended for professional use in vat photopolymerization (SLA, DLP and LCD) additive manufacturing systems operating in the 385–405 nm range.

Final suitability of printed parts must be validated by the user according to the specific application, processing conditions and applicable regulatory requirements.
