Formlabs Flexible 80A Resin


Introducing Formlabs Flexible 80A Resin - the perfect material for optimizing your manufacturing process and rapidly iterating through designs. This Formlabs Flexible 80A Resin is formulated to withstand extensive testing and perform under stress, with an 80A Shore durometer that simulates the flexibility of rubber or other soft-touch materials. Whether you're assessing form, fit, and function or creating prototypes quickly and accurately, this flexible resin will help you get the job done right!

Available for Form 3 generation printers, and Form 2.
Supports print resolutions: 100 and 50 microns.
Post-curing required.


Why Choose Formlabs Flexible 80A Resin?

Create silicone, urethane and rubber-like parts. Produce flexible parts in-house in a matter of hours, replacing outsourcing and molding.


  • Leverage bendable parts that return to shape slowly.

Soft and Strong

  • Stretch and compress parts through repeated cycles without cracking.


  • Create objects that are clear, providing visibility into the model.


  • Support user testing with looks and feels like prototypes that can be put to the test.



Formlabs Flexible 80A Resin is ideal for hard, flexible prototypes and a great alternative to mold making.

Consider Formlabs Flexible 80A Resin for:

  • Handles, grips, and overmolds
  • Seals, gaskets, and masks
  • Cushioning, damping, and shock absorption
  • Cartilage, tendon, and ligament anatomy

Form Wash Settings


10 minutes + 10 minutes


Wash parts printed in Flexible 80A Resin in two cycles, preferably using fresh solvent for the second wash. When washed in TPM, Flexible 80A Resin remains waxy when printed at any layer thickness and requires post-cure. Post-curing removes the waxiness.

Form Cure Settings


10 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 Flexible 80A Resin.
