Very Stiff Material
Rigid 4k Resin has a tensile modulus of 4.1GPa and a low elongation rate. The materials ability to keep an uniform shape while under a lot of stress makes it ideal for high precision and high performance components.
Rigid 4k Resin has a tensile strength of 75 MPA, it has a higher tensile strength than any of the other resins in the Formlabs standard range. It is also stronger than the Rigid 10k Resin.
Resistant to Heat and Chemicals
With a 88 °C @ 0.45 MPa heat deflection temperature, you can be assured that parts produced with Rigid 4000 Resin are resistant to heat. As well as this, the Rigid 4k Resin is very resistant to chemical attack making it suitable for use outdoors, with food or even with hazardous materials
Smooth Surface Finish
Using Rigid 4k Resin produces accurate components which will meet your design tolerances. Rigid 4k Resin also produces parts with a smooth finish, giving any design a visually pleasing aesthetic.
Why Chose Rigid 4k over Rigid 10k
Rigid 4k Resin is less brittle than it’s sister resin, Rigid 10k. Parts made with Rigid 4k Resin are less likely to suddenly fracture, the part will elongate and fail slowly. As well as this, Rigid 4k has a higher ultimate tensile strength than Rigid 10k.
Rigid 4k Resin is commonly used for: Mounts and brackets, Thin walled parts, Jigs and fixtures.
