Choose Engineering Resins For:


Advanced Functionality

Resistance to Stress

Stability Over Time

Grey Pro Resin for Versatile Prototyping

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.

  • Form and fit testing
  • Injection molded product prototypes
  • Mold masters for plastics, silicones, and more
  • Jigs and fixtures for manufacturing

Grey Pro Resin

An all-purpose functional prototyping material, Grey Pro has good elongation, high heat resistance, and low creep.

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.

  • Turbines and fan blades
  • Jigs, fixtures, and tooling
  • Manifolds
  • Electrical casings and automotive housings

Rigid Resin

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.

Durable Resin for Low Friction and Wear

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.

  • Consumer packaging
  • Bushings and bearings
  • Snap fits and flexures
  • Living hinges

Durable Resin

Durable has the highest impact strength of our Engineering Resins. Its low modulus and high elongation make it highly resistant to deformation.

Tough Resin for Rugged Prototyping

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.

  • Sturdy prototypes
  • Interference and press fits
  • Assemblies

Tough Resin

Tough Resin’s high impact strength and compliance make it perfect for parts that need to return to their original shape after force is applied over a brief period.

Flexible Resin for Ergonomic Features

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.

  • Handles, grips, and overmolds
  • Cushioning and dampening
  • Wearables prototyping
  • Packaging
  • Stamps

Flexible Resin

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.

High Temp Resin for Heat Resistance

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.

  • Heat resistant fixtures
  • Housing components
  • Hot air and fluid flow
  • Mold prototyping
  • Environmental testing

High Temp Resin

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.
