Formlabs | Rigid 4000 Resin

$229.00

Rigid 4000 Resin is a glass-filled material that delivers precision and stiffness comparable to PEEK and PEKK thermoplastics. It produces parts with a smooth, matte, polished finish and offers excellent resistance to heat and chemicals.

Ideal for engineering-grade prototypes, load-bearing components, and industrial applications, Rigid 4000 Resin provides the strength and rigidity needed to withstand heavy use without bending.

frequently asked questions

What is Rigid 4000 Resin used for?

It’s ideal for strong, stiff, and precise parts such as brackets, jigs, fixtures, mounts, and functional prototypes that must resist bending.

How does Rigid 4000 compare to Rigid 10K?

Rigid 4000 offers a balance of stiffness and toughness, while Rigid 10K is stiffer and more heat resistant but slightly more brittle.

What are the key mechanical properties of Rigid 4000 Resin?

It has a tensile strength of ~75 MPa, a modulus of ~4 GPa, and low deformation under load, ensuring reliable structural performance.

Is Rigid 4000 resistant to heat and chemicals?

Yes. It maintains stability under elevated temperatures and resists many industrial oils, greases, and solvents.

Which printers are compatible with Rigid 4000 Resin?

It’s validated for Form 3, Form 3+, Form 3B, Form 3B+, and Form 4 printers, optimized for high-strength, precision parts.
