What is Formlabs Flexible 80A Resin?

Formlabs Flexible 80A resin is a translucent, rubber-like SLA material with an 80A Shore hardness and a firm, soft-touch feel. It withstands repeated bending, flexing, and compression, and provides cushioning and shock absorption.

Formlabs Flexible 80A Resin Overview

Applications

Formlabs Flexible 80A resin’s firm, rubber-like feel makes it useful for evaluating flexible parts before investing in production tooling. Its ability to bend and compress is useful for handle and grip prototypes, seal and gasket prototypes, and cushioning features. It can also reproduce flexible anatomical structures for demonstration models.

Key Product Benefits

  • 80A Shore hardness
  • Resistance to repeated bending and compression

Tolerances

For well-designed parts, dimensional accuracy of ±0.3% of the nominal dimension, with a minimum tolerance of ±0.012 in. (±0.3 mm), can typically be achieved. Tolerances may vary depending on part geometry.
