Rigid 10K
Choose Rigid 10K Resin for precise industrial parts that need to withstand significant load without bending. Rigid 10K Resin exhibits a smooth matte finish and is highly resistant to heat and chemicals.
The “10K” in the name represents the material’s tensile modulus. If you need a less stiff material, try Rigid 4000.
- Short-run injection mold masters and inserts
- Heat resistant and fluid exposed components, jigs, and fixtures
- Aerodynamic test models
- Simulates stiffness of glass and fiber-filled thermoplastics
Supports print resolutions: 100 and 50 microns.
Post-curing required.
Requires Resin Tank V2 for Form 3 and Resin Tank LT for Form 2.
High Temp
High Temp Resin offers a heat deflection temperature (HDT) of 238 °C @ 0.45 MPa, the highest among Formlabs resins. Use it to print detailed, precise prototypes with high temperature resistance.
- Hot air, gas, and fluid flow
- Heat resistant mounts, housings, and fixtures
- Molds and inserts
Supports print resolutions: 100, 50 and 25 microns.
Post-curing required with additional thermal treatment to acquire maximum heat deflection temperature of 238°C.
ESD
Reduce risk and increase manufacturing yield by 3D printing custom tools, jigs and fixtures with ESD Resin, protecting your critical electronics components from static discharge. ESD Resin is a cost-effective solution for producing static-dissipative parts designed to endure use on the factory floor.

Resin Tanks
Formlabs Resin Tanks are consumables required for printing with any Formlabs 3D printer which wear over time depending of the material, part orientation and position, layer resolution and model size.
Each material should have it’s own Resin Tank to avoid decrease in print quality and damage to the device.
