Flexible 80A Resin V2

A resilient elastomer that rivals the look, feel, and function of 80A cast urethanes, TPUs, and hard rubbers. Parts snap back into place and withstand repeated bending, tension, and compression. V2 is the only Flexible 80A formulation we print, and it prints matte black.

Summary & Key Takeaways

V2 Formulation, Matte Black: Every Flexible 80A part we print is the V2 formulation, and every figure on this page is a V2 figure.
Simulates 80A Urethanes and TPU: 83A Shore hardness with the look and feel of cast urethane and hard rubber.
Tear Resistant Where It Matters: 28 kN/m tear strength, roughly twice Flexible 50A's, so thin seals and webs survive handling.
Not for Long-Term Compression: An 85% compression set at 70 °C means it is not a substitute for a molded gasket under permanent clamp load.

Why Choose Flexible 80A Resin V2?

The harder of the two flexible resins, and the one to choose when a part must flex repeatedly without tearing.

Snaps Back, Cycle After Cycle

56% pendulum rebound and 230% elongation at break mean bumpers, grips, and living features return to shape after bending, tension, and compression instead of taking a set.

Twice the Tear Strength of 50A

At 28 kN/m, thin webs, seal lips, and strap features survive handling and support removal that would start a tear in a softer elastomer, which is usually what limits printed rubber parts.

Hard-Rubber Look and Feel

83A Shore hardness puts it in the range of 80A cast urethanes and TPUs, so grips, overmold mock-ups, and handles feel like the production part rather than like a prototype.

Ribbed elastomeric part printed in Formlabs Flexible 80A Resin V2, shown as printed on its support structure before support removal — A ribbed V2 part as printed, still on its supports. Support removal is the load case the higher minimum wall exists for.

Source: Formlabs SLA design specifications for Form 3 / Form 4 generation printers, adapted to hold walls to a higher minimum than Formlabs' published figures. Elastomeric parts tear and distort during support removal at wall thicknesses a rigid resin tolerates, so Flexible 80A V2 is held to a higher minimum wall than our rigid resins. Thin seal lips and webs should also be backed by a thicker section wherever the geometry allows. These are general guidelines; cross-section, hole depth, and part geometry can shift the safe minimums for a specific design. Maximum build size reflects our largest-format SLA printer; actual build size depends on which machine your order routes to.

Frequently Asked Questions

Everything you need to know about designing, ordering, and using Flexible 80A V2 parts on Form Now.

What is Flexible 80A Resin V2, and is it the version Form Now prints?

Flexible 80A Resin V2 is a resilient stereolithography (SLA) elastomer from Formlabs that rivals the look, feel, and function of 80A cast urethanes, TPUs, and hard rubbers. Parts snap back into place and withstand repeated bending, tension, and compression. V2 is the only Flexible 80A formulation Form Now prints, so every specification, photograph, and design rule on this page describes the material you will receive. It prints matte black.

How flexible and tough is Flexible 80A Resin V2?

Flexible 80A Resin V2 has a Shore hardness of 83A, a tensile strength of 10 MPa, 230% elongation at break, a tear strength of 28 kN/m, and 56% pendulum rebound. That combination makes it the material to reach for when a part has to flex repeatedly without a tear starting at a thin feature or a hole.

What is Flexible 80A Resin V2 used for?

Flexible 80A Resin V2 is commonly used for bumpers and flexible enclosures, seals and gaskets, shock-absorbing padding, grips and handles, and overmold mock-ups where a hard-rubber feel is needed.

Should I choose Flexible 80A V2 or Flexible 50A?

Choose Flexible 80A V2 for a hard-rubber feel that resists tearing: 83A Shore hardness, 28 kN/m tear strength, and 10 MPa tensile strength. Choose Flexible 50A when the part must be genuinely soft and squeezable, at 55A Shore hardness, closer to the silicones and soft rubbers it is meant to simulate.

Can Flexible 80A Resin V2 be used for a permanent gasket?

It is better suited to prototypes and short-term use than to permanent sealing. Its compression set at 70 °C is 85%, meaning a part held under sustained compression at temperature will not fully recover its original thickness. For a permanent seal under continuous clamp load, a molded elastomer is the right answer.

What are the minimum wall thickness design rules for Flexible 80A V2?

We recommend a minimum wall thickness of 1.5 mm for elastomeric resins, higher than the 1.0 mm we hold rigid resins to, because thin elastomer walls tear and distort during support removal. Holes should be at least 1.0 mm in diameter. Maximum single-part build size is 353 x 196 x 350 mm.
