Ultra-Stiff Resin for High-Performance Prototypes
Rigid 10K Resin is the stiffest Formlabs resin, combining extreme rigidity, glass reinforcement, and high thermal resistance. It’s designed for injection molding, jigs, and heat-resistant parts.
Rigid 10K Resin
The Resin That Stays Rigid—Even When the Heat Is On.

Rigid 10K Resin
Ultra-high stiffness
– Tensile modulus of 10–11 GPa for structural strength.
Exceptional flexural strength
– Reaches 126–158 MPa after curing for load-bearing use.
High HDT
– Withstands 218–238 °C @ 0.45 MPa after curing.
Chemical resistance
– Performs reliably in chemically demanding environments.
Injection mold ready
– Suitable for short-run mold masters and inserts.
Industrial precision
– Prints with smooth, accurate surface quality for engineering use.

Best for:
High-precision fixtures, measurement equipment, structural testing, and applications requiring extreme rigidity
