Product Overview


Formlabs Durable Resin
Durable Resin is a pliable, impact-resistant, and lubricious material for squeezable parts and low-friction assemblies. Parts printed in Durable Resin are robust and have low friction, with similar strength and stiffness to polyethylene (PE) and a coefficient of friction is comparable to Delrin® (POM). Choose Durable Resin for squeezable prototypes, low-friction assemblies, and jigs and fixtures undergoing significant impacts.

Why Choose Durable Resin?
Durable Resin is a soft and pliable material that bends without breaking while maintaining good rigidity.
Pliable
Produce parts that are highly resistant to deformation before breaking.
Lubricious
Create parts that are smooth and glossy like an everyday plastic.
Impact-Resistant
Leverage high-impact strength for rugged prototyping.
Strong and stiff
Simulate the strength and stiffness of polyethylene (PE).




Applications
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
NOTES
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
NOTES
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.
