Durable Resin
Strength and Stiffness Similar to HD/LD Polyethylene (PE)
Formlabs Durable resin is an engineering 3D printing material that is ideal for squeezable parts and low-friction assemblies. It has similar characteristics such as strength and stiffness with the high-density or low-density (HD/LD) polyethylene (PE). Parts or prototypes 3D-printed in Durable resin can handle repeated compression, stretching, flexing and will slightly strain without breaking.
Make pliable yet Durable 3D-printed parts or prototypes.
Durable resin is part of Formlabs’ tough, durable family of SLA 3D printing resins. Its strength and stiffness are similar to polyethylene (PE), and its friction coefficient is comparable to Delrin® [polyoxymethylene | POM].

Why Choose Durable Resin?
Strong and Stiff Polyethylene (PE) with a Smooth Finish.
The specific formulation of Formlabs Durable resin makes it ideal for creating parts that simulate the strength and stiffness of polyethylene (PE) and have a smooth and glossy finish comparable to that of any everyday plastic.
Excellent Properties
Need to make parts or prototypes that handle compression, stretching, bending, and impacts without breaking? Then, Durable resin is your choice.

Post Processing
FORM WASH SETTINGS
DURATION
20 minutes in IPA
NOTES
Tackiness has been noticed on the surfaces of parts washed in IPA containing over 10% resin concentration. If your parts remain tacky after washing, switch to a new solvent. Avoid soaking Durable Resin in solvent for more than 20 minutes, as prolonged exposure to solvent can impact the final part’s quality.
FORM CURE SETTINGS
DURATION TEMPERATURE
60 minutes 60 °C
NOTES
For components printed using an engineering-oriented resin (such as those within the Rigid, Tough & Durable, and Flexible & Elastic categories), post-curing guarantees the attainment of their peak mechanical properties, ensuring they perform as intended. Only one specific post-curing duration is recommended for Durable Resin.
