NextGen 3Dresyn R290D90 ultra rigid up to 290C with Shore D90
Product description
NG 3Dresyn R290D90 is an extra hard, high-temperature resistant photopolymer formulation designed for advanced engineering applications in SLA, DLP and LCD 3D printing workflows. The material delivers very high stiffness, dimensional stability and extreme thermal resistance, enabling the fabrication of parts operating under demanding thermal conditions.
This formulation is based on a synthetic resin system engineered to achieve high heat deflection performance while maintaining excellent printability and surface resolution.

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
