Formlabs Durable Resin


Introducing Formlabs Durable Resin - the perfect resin for optimizing your manufacturing process and rapidly iterating through designs. This engineering resin is formulated to withstand extensive testing and perform under stress, making it ideal for assessing form, fit, and function. Whether you're creating prototypes or final products, this durable resin will help you get the job done right!

This amazing resin is perfect for creating squeezable parts or low-friction assemblies that will last a long time. It's easy to use with any 3D printer, so you can create whatever your heart desires! With its superior strength and flexibility, this durable resin is sure to meet all your needs.

  • Squeezable prototypes and low friction assemblies
  • Jigs and fixtures undergoing significant impacts
  • Low friction assemblies and non-degrading surfaces
  • Simulating the strength and stiffness of polyethylene (PE)

Supports print resolutions: 100 and 50 microns.
Post-curing required.


Why Choose Formlabs Durable Resin?

Formlabs Durable Resin is a soft and pliable material that bends without breaking while maintaining good rigidity.


  • Produce parts that are highly resistant to deformation before breaking.


  • Leverage high-impact strength for rugged prototyping.


  • Create parts that are smooth and glossy like an everyday plastic.

Strong and stiff

  • Simulate the strength and stiffness of polyethylene (PE).



Formlabs Durable Resin is ideal for prototyping consumer products, packaging, and low-friction and low-wear moving parts.

Consider Durable Resin for:

  • Squeezable prototypes
  • Low friction assemblies and non-degrading surfaces (like ball joints)
  • Jigs and fixtures undergoing significant impacts
  • Snap-fit parts and flexures



Form Wash Settings


20 min in IPA


Tackiness has been observed on part surfaces when washed in IPA with more than 10% resin concentration. Use fresh solvent if your parts remain tacky after washing. Do not leave Durable Resin in solvent for longer than 20 minutes total, as excessive solvent exposure affects the quality of the final part.

Form Cure Settings


60 min


60 °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 Durable Resin.
