3Dresyn Bioflex A20 MF Monomer-Free Ultra-Soft Biocompatible Resin

Product description

3Dresyn® Bioflex A20 MF is a very soft biocompatible monomer-free photopolymer resin developed for applications requiring extremely high flexibility, soft-touch behaviour and elastic recovery while maintaining dimensional stability and very high printing resolution.

The formulation is based on monomer-free systems designed to minimize residual reactive species after validated cleaning and post-curing.

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.
