3Dresyn UHV-SFA30 Bio, Biocompatible soft and flexible resin with Shore A30 for Hot Lithograghy HL and Viscous Lithography Manufacturing VLM

Product description

3Dresyn® UHV-SFA30 Bio is a non-yellowing soft and flexible photopolymer developed for Hot Lithography (HL) and Viscous Lithography Manufacturing (VLM) applications requiring very low hardness, high elongation and rubber-like behavior with biocompatible-grade safe handling.

Application framework

Processing note

Note: very soft photopolymers may exhibit strong dependence on geometry, curing state and loading conditions. Final softness, flexibility, elongation and durability must be validated by the user under the intended application and processing conditions.

Testing & processing disclaimer

Material performance depends on printer type, thermal control, exposure conditions, geometry and full workflow implementation. Mechanical performance, flexibility, elongation and final suitability must be validated by the user for each specific application.
