3Dresyn IM-HF-FAS Bio Hard Flexible Acetone-Soluble Sacrificial Resin

Product description

3Dresyn® IM-HF-FAS Bio is a fast acetone-soluble hard and flexible photopolymer developed for printing sacrificial materials requiring rapid dissolution in acetone using SLA, DLP and LCD 3D printing technologies.

The material combines hard and flexible thermoplastic behavior with fast solvent removal, enabling the production of sacrificial components for advanced manufacturing workflows.
