3D Printing Materials for Engineering, Manufacturing, and Product Design
Our library of versatile, reliable Engineering Resins is formulated to help you reduce costs, iterate faster, and bring better experiences to market.
Choose Engineering Resins For:
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
- Electrical casings and automotive housings
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
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
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
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
