Engineering Resins


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


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


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

  • Assemblies

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


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

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.

  • Wearables and consumer goods prototyping

  • Medical models and devices

  • Compliant features for robotics

  • Special effects props and models

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.
