3Dresyn TFD70 ESD, tough and foldable, ESD compliant

Product description

3Dresyn® TFD70 ESD is a tough, flexible photopolymer formulation with integrated electrostatic discharge (ESD) properties, designed for advanced engineering applications in SLA, DLP and LCD 3D printing workflows. The material combines flexibility, high impact resistance and durability with controlled electrical conductivity for ESD-safe environments.

This formulation is engineered to provide non-brittle behavior, allowing parts to flex and deform without breaking while maintaining excellent printability and surface resolution.
