Rigid and Structural Resins

Produce flexible parts in-house.

Use the Formlabs family of Flexible and Elastic Resins and replace outsourcing and molding of silicone, urethane, and rubber parts.

Ideal for robotics, anatomical models and medical devices, consumer goods prototyping and special effects props and models.

Various 3D Printed Models using Formlabs Engineering Resins

Glass-filled Rigid 4000 Resin prints with a smooth, polished finish and is ideal for stiff and strong parts that can withstand minimal deflection.

Consider Rigid 4000 Resin for general load-bearing applications including: Turbines and fan blades; Jigs, fixtures and tools; Manifolds; Electrical casings and automotive housings.

The “4000” in the name represents the material’s tensile modulus. If you need a stiffer material, try Rigid 10K Resin.

  • Supports print resolutions: 100 and 50 microns

  • Post-curing required

  • Compatible with: Form 2 (Requires Resin Tank LT); Form 3; Form 3B

Rigid 10K Resin

This highly glass-filled resin is the stiffest material in the 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.

The “10K” in the name represents the material’s tensile modulus. If you need a less stiff material, try Rigid 4000 Resin.

  • Supports print resolutions: 100 and 50 microns

  • Post-curing required

  • Compatible with: Form 2 (Requires Resin Tank LT); Form 3; Form 3B

Grey Pro Resin offers high precision, moderate elongation, and low creep.

Grey Pro is great for concept modelling and functional protoyping, especially for parts that will be handled repeatedly.

Applications for Grey Pro could include: Form and Fit testing; Injection molded product prototypes; Mold masters for plastics, silicones and more; Jigs and fixtures for manufacturing.

  • Supports print resolutions: 100 and 50 microns

  • Post-curing required

  • Compatible with: Form 2 (Requires Resin Tank LT); Form 3; Form 3B
