3Dresyn FA40 ESD, flexible, ESD compliant

Product description

3Dresyn® FA40 ESD is a highly flexible photopolymer formulation with integrated electrostatic discharge (ESD) properties, designed for advanced engineering applications in SLA, DLP and LCD 3D printing workflows. The material provides soft, rubber-like behavior with very high elasticity and impact resistance, combined with controlled electrical conductivity for ESD-safe environments.

This formulation is based on a monomer-based (MB) system engineered to achieve maximum flexibility and deformation capability, requiring proper post-curing and cleaning to reach final material performance.
