Formlabs Formlabs Flexible 80A Resin - 5L
Formlabs Flexible 80A Resin is a translucent material designed for crafting durable, rubber-like prototypes that can bend and stretch, suitable for rapid in-house production. With 80A Shore hardness, it is ideal for making seals, grips, and cushioning. Compatible with a range of Formlabs printers and tanks, it features an ultimate tensile strength of 8.9 MPa and elongates up to 120% at break.
- Mimics hard-rubber flexibility
- Bendable parts return to shape slowly
- Translucent for internal visibility, streamlines design
- Cartridge compatible with Form 3 series / 2 3D printers

| Notes | Notes |
| 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. |
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. |
