Formlabs Rigid 10K Resin

Introducing Formlabs Rigid 10K Resin - the perfect material for optimizing your manufacturing process and rapidly iterating through designs. This highly glass-filled resin is the stiffest in our engineering portfolio, making it ideal for assessing form, fit, and function under stress. Whether you’re prototyping or producing parts with high accuracy requirements, this resin will help you get the job done right! With its superior strength and durability, you can trust that your projects are built to last.

Get the most precise industrial parts with Formlabs Rigid 10K Resin. This material is designed to withstand significant load without bending, and exhibits a smooth matte finish that's highly resistant to heat and chemicals. The “10K” in the name represents its tensile modulus - if you need something less stiff, try our Rigid 4000 Resin instead! Supports print resolutions of 100 and 50 microns for detailed prints every time. Post-curing required for best results. Order your Formlabs Rigid 10K Resin today!


Why Choose Rigid 10K Resin?

Rigid 10K Resin is a high performance material that is strong, completely stiff, and stable.

Extremely Stiff

  • Resistant to deformation under a variety of forces, pressures, and torques.

High Thermal and Chemical Resistance

  • Withstands high temperatures and a variety of chemicals.


  • Produce strong, detailed, and accurate molds or models.

Incredible Surface Quality

  • Exhibits a smooth matte finish.


Rigid 10K Resin is ideal for creating rigid, strong, industrial-grade prototypes. Rigid 10K Resin can be faster and easier to print compared to milling aluminum and steel.

Consider Rigid 10K Resin for:

  • 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



Form Wash Settings


10 minutes + 10 minutes​ in IPA


Rigid 10K Resin contains glass particles, which strengthens printed parts. Maintain separate wash buckets to prevent glass particles adhering to parts printed with other resins. Parts with two wash times require two wash cycles. For the second wash cycle, use clean solvent. The first wash cycle removes the bulk of the resin, while the second cycle fully cleans the parts.

Form Cure Settings


60 min


70 °C


For parts printed in an engineering-focused resin (such as those in the Rigid, Tough & Durable, and Flexible & Elastic families), post-curing ensures that the parts reach their optimal mechanical properties and can function as designed. There is only one recommended post-curing time for Rigid 10K Resin V1. Optionally, after post-curing, heat the printed part in a non-food oven at 90 °C for 125 minutes for a higher heat deflection temperature.
