Rigid 4000

A Top-Tier Glass-Filled SLA 3D Printing Material

Discover Formlabs' Rigid 4000, the cutting-edge SLA 3D printing material engineered to rival the stiffness of thermoplastics like PEEK (Polyetheretherketone) and PEKK. It is ideal for producing stiff, strong end-use parts with a smooth, polished finish, capable of withstanding minimal deflection.

Glass-Reinforced Engineering Resin

Rigid 4000 resin is an engineering-grade material designed for applications that demand high stiffness and precision. This resin contains glass reinforcement, resulting in 3D-printed parts with a smooth finish and excellent resistance to deformation over time. It is an ideal choice for long-lasting and general load-bearing applications.

Parts made from Rigid 4000 are highly thermally and chemically resistant, and they will maintain dimensional stability under load. However, it’s important to note that they will fail under pressure and become brittle if pushed to their limits.

NOTES

Rigid 4000 Resin contains glass particles, which strengthen printed parts. Maintain separate wash buckets to prevent glass particles from adhering to parts printed with other resins.

When using engineering-focused resins (like those in the Rigid, Tough & Durable, and Flexible & Elastic families), post-curing is vital to ensure that the parts reach their optimal mechanical properties and can perform as intended. For Rigid 4000 Resin V1, there is only one recommended post-curing time.
