Formlabs Rigid 4000 Resin is an exceptionally stiff and stable material. This material, which is reinforced with glass, offers a very high stiffness and polished finish. Rigid 4000 Resin is highly resistant to deformation over time, and it is best used for printing thin walls and features.
Rigid 4000 Resin has the highest modulus of all Formlabs materials. Not only does it have a great impact strength, Rigid 4000 Resin is also very heat resistant and stable. It is, however, also more brittle than Durable and Tough resin. The Rigid 4000 Resin can only be printed with the LT Resin Tank.
The Rigid 4000 Resin can be used to print items, such as turbines, fan blades, jigs, fixtures, toolings, manifolds, electrical casings and automotive housings.
