Rigid

Rigid Resin is reinforced with glass to offer very high stiffness and a polished finish. This material is highly resistant to deformation over time and is great for printing thin walls and features.

  • Turbines and fan blades

  • Jigs, fixtures, and tooling

  • Manifolds

  • Electrical casings and automotive housings


ORDER RIGID RESIN NOW

Rigid

Rigid Resin has the highest modulus of all Formlabs materials. It has great impact strength, heat resistance, and stability, but is more brittle than Tough and Durable.

Handling & Safety

Our resins have been designed to be as safe as possible, but nevertheless, working with them requires care, similar to working with common adhesives or household cleaners. They do not have volatile solvents so special ventilation is not required, though skin contact should be avoided.
