3Dresyn R290D90 ESD ultra rigid up to 290C, ESD compliant

Product description

3Dresyn® R290D90 ESD is an extra hard, high-temperature resistant photopolymer formulation with integrated electrostatic discharge (ESD) properties, designed for advanced engineering applications in SLA, DLP and LCD 3D printing workflows. The material combines ultra-high rigidity, dimensional stability and extreme thermal resistance with controlled electrical conductivity for ESD-safe environments.

This formulation is based on a synthetic resin system engineered to achieve high heat deflection performance while maintaining excellent printability, surface resolution and ESD compliance.

Thermal performance note

High Heat Deflection Temperature (HDT) photopolymer resins, despite their rigidity, may exhibit brittle behavior and reduced lifetime under prolonged thermal exposure. For applications requiring long-term durability at high temperatures, alternative materials such as machined polyimide, or injection-molded PolyAmide Imide (PAI) or similar high-performance polymers, should be considered.

Testing & processing disclaimer

Material properties are measured under controlled laboratory conditions and may vary depending on printer type, exposure conditions, layer thickness, build orientation and post-processing workflow.

Disclaimer

This material is supplied as a professional manufacturing material for engineering and prototyping workflows. It is not marketed as a finished product. Final part performance and suitability must be validated by the user according to the intended application.
