3Dresyn TD90 ESD, Rigid & Tough, ESD compliant

Product description

3Dresyn® TD90 ESD is an extra hard, high-performance photopolymer formulation with integrated electrostatic discharge (ESD) properties, designed for advanced engineering applications in SLA, DLP and LCD 3D printing workflows. The material combines high rigidity, excellent mechanical strength and enhanced impact resistance with controlled electrical conductivity for ESD-safe environments.

This formulation is based on a synthetic resin system engineered to provide a balanced combination of stiffness, toughness and durability while maintaining excellent printability and surface resolution.
