3Dresyn SF soft & flexible

Product description

3Dresyn SF is a soft and flexible photopolymer formulation designed for applications requiring low stiffness, high elasticity and reliable deformation without fracture. The material enables the fabrication of soft components with elastomer-like behavior and consistent mechanical response.

This formulation is optimized for high-resolution printing and very low viscosity processing, supporting fine feature fabrication in soft and flexible applications.
