Grey Pro Resin
- Grey Pro Resin offers high precision, moderate elongation, and low creep. This material is great for concept modeling and functional prototyping, especially for parts that will be handled repeatedly.
- Good for: form and fit testing; prototyping injection molded products; mold masters for plastics, silicones, and more; jigs and fixtures for manufacturing.
- Rigid Resin is filled 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 has the highest modulus of all Formlabs materials. It has great impact strength, heat resistance, and stability, but is more brittle than Tough and Durable.
- Good for: turbines and fan blades; jigs, fixtures, and tooling; manifolds; electrical casings and automotive housings.
- Tough Resin balances strength and compliance, making it the ideal choice for prototyping strong, functional parts and assemblies that will undergo brief periods of stress or strain.
- Good for: sturdy prototypes; interference and press fits; assemblies.
- With low modulus, high elongation, and high impact strength, Durable Resin produces parts with a smooth, glossy finish and high resistance to deformation. Use this material for applications requiring minimal friction.
- Durable has the highest impact strength of our Engineering Resins. Its low modulus and high elongation make it highly resistant to deformation.
- Good for: consumer packaging; bushings and bearings; snap fits and flexures; living hinges.
- Use Flexible Resin to produce parts that bend and compress. Flexible is excellent for simulating soft-touch materials and adding ergonomic features to multi-material assemblies.
- Flexible is a softer material, with a durometer of 80A close to that of rubbers used for shoe soles or tire treads. This elastic material has a low tensile modulus and high elongation.
- Good for: hearables prototyping; packaging; stamps.
High Temp Resin
- High Temp Resin has a heat deflection temperature (HDT) of 289 °C @ 0.45 MPa—the highest on the 3D printing materials market. Use it to print models for environmental testing, or create molds and masters for production processes like casting and thermoforming.
- High Temp has the highest HDT @ 0.45 MPa of all the Engineering Resins. High Temp has low thermal expansion and high tensile modulus, or stiffness.
- Good for: heat resistant fixtures; housing components; hot air and fluid flow; mold prototyping; environmental testing.
