3Dresyn RIC-HFA90 Bio, Biocompatible hard and flexible resin with Shore A90 for Resin Injection and Casting
Product description
3Dresyn RIC-HFA90 Bio is a hard & flexible resin for injection and casting.
This material is designed to be hard and flexible without breaking, while remaining rigid with superior shattering resistance at high thickness. It provides properties similar to hard and flexible rubber for resin injection and casting workflows.
Application framework
Designed for resin injection and casting workflows, including gravity casting and injection in molds, for fabrication of hard and flexible parts with high shattering resistance.
