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.
