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 4000

Stiff, Strong, Engineering-Grade Prototypes

Rigid  4000 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.


  • Mounts and brackets

  • Thin-walled parts

  • Turbines and fan blades

  • Jigs, fixtures, and tooling

  • Manifolds

  • Electrical casings and automotive housings

  • Simulates stiffness of PEEK


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


Rigid 10K

Rigid, Strong, Industrial-Grade Prototypes

This highly glass-filled resin is the stiffest material in our engineering portfolio. Choose Rigid 10K Resin for precise industrial parts that need to withstand significant load without bending. Rigid 10K Resin exhibits a smooth matte finish and is highly resistant to heat and chemicals.


  • Short-run injection mold masters and inserts

  • Aerodynamic test models

  • Heat resistant and fluid exposed components, jigs, and fixtures

  • Simulates stiffness of glass and fiber-filled thermoplastics


Tough 1500

Ideal for resilient prototyping

Tough 1500 Resin is the most resilient material in our functional family of Tough and Durable Resins. Choose Tough 1500 Resin for stiff and pliable parts that bend and spring back quickly.

  • Prototypes that repeatedly bend and quickly return to shape

  • jigs and fixtures requiring repeated deflections

  • Simulating the strenght and stiffness of polypropylene (PP)

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


Tough 2000

Ideal for rugged prototyping

Tough 2000 Resin is the strongest and stiffest material in our functional family of Tough and Durable Resins. Choose Tough 2000 Resin for prototyping strong and sturdy parts that should not bend easily.

  • Strong and stiff prototypes

  • Jigs and fixtures requiring minimal deflection

  • Simulating the strength and stiffness of ABS


Flexible 80A

Hard Flexible Prototypes

Flexible 80A Resin is the most stiff soft-touch material in our library of Flexible and Elastic Resins, with an 80A Shore durometer to simulate the flexibility of rubber or TPU. Balancing softness with strength, Flexible 80A Resin can withstand bending, flexing, and compression, even through repeated cycles


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.
