Rigid 4K Resin

Formlab’s Rigid 4K Resin is best for parts that need ZERO give. This material has zero flexibility which makes it ideal for mounts and brackets due to its high tensile strength and stiffness. This material closely resembles PEEK.

PROS OF

Rigid 4K Resin

When it is a perfect material choice

Great for functional parts that need to look good and work well

Provides some thermal and chemical resistance

Extremely high stiffness and strength

Great for prototyping parts with thin walls

Great for printing mounts, brackets, jigs and fixtures

CONS OF

Rigid 4K Resin

When to seek other material options

Supports are necessary for printing which can affect the visual quality of the part

Rigid nature of material makes removing supports and sanding harder than other materials

Custom colors not available, material is white in color

Not available on SLA XL build volume

Not ideal for parts that require any flexibility

PRINT SETTINGS

You need 3D printing and you need it FAST! That’s why we offer some of the quickest turnaround times in the nation.

QUALITY FOR

Rigid 4K Resin

This number of microns determines how thick each layer is. The smaller the micron count, the thinner the layer, this results in higher surface detail, better surface finishes and less stepping!
