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.
Whether you’re optimizing your manufacturing process, rapidly iterating through designs, or assessing form, fit, and function, Formlabs Engineering Resins are formulated to withstand extensive testing and perform under stress.
Rigid 4k Resin has one of the highest modulus of all Formlabs materials, second only to Rigid 10k. It has great impact strength, heat resistance, and stability, but is more brittle than Tough and Durable.
Rigid 4k has a similar stiffness to PEEK and has a more transparent finish compared to Rigid 10k.
Available layer heights: 100 and 50 microns.
