Rigid Resin

Functional Resins
High detailStrongFunctionalSmooth

Rigid resin is reinforced with glass to offer very high stiffness and a polished finish, with mechanical properties often compared to PEEK and other glass-filled engineering thermoplastics. It's highly resistant to deformation over time under sustained load, and its stiffness allows for thinner walls and finer features than most other resins support. This comes with a trade-off: Due to its high stiffness, rigid resin is more brittle than tough or durable resin, so it isn't the right choice for parts that need to absorb sudden impact. Rigid resin suits housings, fixtures, jigs, and structural components that need to hold a precise shape under load without bending.

Rigid resin parts have a smooth, matte surface with a high level of fine detail, similar to the general resin baseline; the glass reinforcement doesn't create a rough or grainy texture.
