Formlabs Rigid 4000 Resin


Introducing Formlabs Rigid 4000 Resin - the perfect resin for optimizing your manufacturing process and rapidly iterating through designs. This glass-filled resin prints with a smooth, polished finish that is ideal for stiff and strong parts that can withstand minimal deflection. Whether you're assessing form, fit or function, this engineering resin is formulated to perform under stress and stand up to extensive testing.

The “4000” in the name represents this material's tensile modulus, making it a great choice if you need something stiffer than other materials. This resin is designed to support print resolutions of 100 and 50 microns, so you can be sure that your prints will come out looking their best!

Form Wash Settings


15 minutes​ in IPA


Rigid 4000 Resin contains glass particles, which strengthens printed parts. Maintain separate wash buckets to prevent glass particles adhering to parts printed with other resins.

Form Cure Settings


15 min


80 °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 4000 Resin V1.
