Rigid Resin
Rigid Resin for Stiffness and Precision
Rigid Resin is reinforced with glass to offer very high stiffness and a polished finish. This material is highly resistant to deformation over time and is great for printing thin walls and features.
Rigid Resin is ideal for:
- Turbines and fan blades
- Jigs, fixtures, and tooling
- Manifolds
- Electrical casings and automotive housings
Requires Resin Tank V2 for Form 3 and Resin Tank LT for Form 2. Rigid Resin decreases the lifetime of resin tanks. Read more about Resin Tank LT lifetime and Form 3 Resin Tank lifetime.
| Grey Pro Resin | Rigid Resin | Standard Resin | |
|---|---|---|---|
| Flexural Modulus (GPa) | 2.0 GPa | 3.7 GPa | 2.2 GPa |
| Tensile Modulus (GPa) | 2.6 GPa | 4.1 GPa | 2.8 GPa |
| Elongation (%) | 13.0% | 5.6% | 6.2% |
Technical Data
Rigid Resin has the highest modulus of all Formlabs materials. It has great heat resistance and stability, but is more brittle and less impact resistant than Tough Resin and Durable Resin.

Elastic Resin
Elastic Resin for Soft Flexible Parts
Our softest Engineering Resin, this 50A Shore durometer material is suitable for prototyping parts normally produced with silicone. Choose Elastic Resin for parts that will bend, stretch, compress, and hold up to repeated cycles without tearing.
Elastic Resin is ideal for:
- Wearables and consumer goods prototyping
- Medical models and devices
- Compliant features for robotics
- Special effects props and models
Requires Resin Tank V2 for Form 3 and Resin Tank LT for Form 2. Elastic Resin decreases the lifetime of resin tanks. Read more about Resin Tank LT lifetime and Form 3 Resin Tank lifetime.
Technical Data
Elastic Resin is the softest of our Engineering Resins, with a Shore durometer of 50A as well as high elongation and energy return. With high tear strength, this material can withstand repeated cycles.

Flexible Resin
Flexible Resin for Hard Flexible Parts
An 80A Shore durometer material for more rigid flexible parts with a matte-black soft-touch finish. Choose Flexible Resin to create ergonomic features as part of larger assemblies.
Flexible Resin is ideal for:
- Cushioning and damping
- Wearables and consumer goods prototyping
- Handles, grips, and overmolds
Technical Data
Flexible Resin has a Shore durometer of 80A, close to that of rubbers used to produce shoe soles or tire treads. This material has low tensile modulus and high elongation.

High Temp Resin
High Temp Resin for High Thermal Stability
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.
High Temp Resin is ideal for:
- Hot air, gas, and fluid flow
- Heat resistant mounts, housings, and fixtures
- Molds and inserts
Technical Data
High Temp Resin offers a heat deflection temperature (HDT) of 238 °C @ 0.45 MPa, the highest among Formlabs resins. Materials with higher HDT typically map to lower elongation.
| Material | Heat Deflection Time @ 0.45 MPa (post-cured)¹ | Elongation at Break (post-cured)² |
|---|---|---|
| High Temp | 238°C | 2.3% |
| Standard | 73.1°C | 6.2% |
| Rigid | 88°C | 5.6% |
| Grey Pro | 77.5°C | 13% |
| Tough 2000 | 63 °C | 48% |
¹ Heat Deflection Temperature data obtained using the ASTM D 648-16 method.
