Formlabs Flexible 80A Resin Form 4 1 L is an elastomeric SLA resin for printing soft inserts and fixtures. A fixture made from this resin protects a precision component and withstands repeated use. The V2 formula uses the technology of Form 4 series printers. The part returns to its shape after repeated deformation, and its surface is matte and non-tacky.
Key features and benefits
- Rebound (pendulum method): 56% — The value is comparable to 80A cast urethanes, so the part returns to its shape after loading.
- Tear strength: 28 kN/m — The value is twice that of the previous version, so the part better resists tearing under tension.
- Elongation at break: 230% — This figure is also twice that of the previous version, so parts withstand stretching without breaking.
- Fatigue life (Ross Flex): 5 times more cycles — This is relative to the previous version: covers and fixtures withstand repeated loading for longer.
- Ageing resistance: after 1000 h of accelerated indoor ageing, the part retains 87% of its initial elongation at break. This supports a long service life for covers and fixtures.
- Appearance and surface: the matte black surface of parts made from Formlabs Flexible 80A Resin Form 4 1 L is non-tacky. It reproduces the look and feel of cast urethane.
- Updated V2 formula: rebound is 4 times higher than in the previous version, and appearance and ageing are improved.
Applications
Parts made from Formlabs Flexible 80A Resin Form 4 1 L withstand repeated stretching.

Elastomer tooling works with precision metal parts.

Protective connector caps are an example of covers made from this material.

Resilient housings serve as a protective shell for devices.

- Functional prototypes and end-use parts: the resin is comparable to 80A cast urethanes and hard rubber, and the parts are tear-resistant.
- Soft inserts, tooling and fixtures: an elastic holder protects precision components and finished surfaces and withstands repeated use.
- Seals, gaskets and covers: the part recovers its shape after compression and withstands 5 times more cycles than the previous version.
- Shock-absorbing bumpers and housings: 56% rebound returns the bumper to its shape, and tear resistance keeps the housing intact.
- Overlays and handles: the matte black non-tacky surface feels like cast urethane to the touch, so it is suitable for handles and overlays.
