Formlabs Flexible 80A Resin (Form 4) - 1L is a stiff, soft-touch, translucent elastomer designed for Australian engineering labs to create silicone, urethane, and rubber-like parts in-house.

With an 80A Shore durometer, parts printed in Formlabs Flexible 80A Resin (Form 4) - 1L can withstand repeated bending, flexing, and compression cycles without failure. This material is the ideal choice for prototyping rubber-like parts with the flexibility of harder rubber or TPU, providing high energy return and durability.

Thermal & Performance Note

As an elastomer, this resin is sensitive to ambient temperature. At its Glass Transition ($T_g$) of 15°C, parts will become stiffer. For optimal performance, use in environments between 18°C and 40°C. Note: This material is not autoclave-safe.

Applications of Formlabs Flexible 80A Resin (Form 4) - 1L

This resin is ideal for hard, flexible prototypes and serves as a superior alternative to traditional mold making. Engineers utilize Formlabs Flexible 80A Resin (Form 4) - 1L for high-performance applications including:

  • Handles, grips, and overmolds
  • Industrial seals, gaskets, and masks
  • Cushioning, damping, and shock absorption
  • Medical simulation (cartilage, tendon, and ligament anatomy)

Technical Specifications (Post-Cured)

  • Shore Hardness: 80A
  • Tensile Strength: 8.9 MPa
  • Elongation at Failure: 120%
  • Appearance: Translucent / Clear

System Compatibility

This 1L cartridge is exclusively compatible with the Formlabs Form 4 and Form 4B LFD print engines. It is a liquid photopolymer and does not have a filament diameter.
