Formlabs Flexible Resin is a functional elastomer used for producing rigid and flexible items. It has been custom-formulated to withstand bending and compression and to perform under stress. This 80A Shore durometer material has mechanical properties close to the ones of rubbers featuring low tensile modulus and high elongation. As part of Formlabs Engineering resins, it has been widely used to create a variety of ergonomic and soft-touch models, compressible parts, packaging, stamps, grips, dampers, and more. Flexible Resin gives the model a matte-black finish.

Formlabs Flexible Resin is a viscous material. Due to its viscosity, it takes a bit to level out when poured into the resin tank. Thus, you might fill the container only to three-quarters to avoid overfilling. Flexible Resin has been optimized for use on Form 2 3D printers. According to the company, a new version for Form 3 will soon be released. 

When printing flex models, pay particular attention to the print settings suggested by the manufacturer. For example, Formlabs suggests printing parts with a minimum base thickness of 1.25mm. When printing large products, it suggests designing a touch-point of at least 2.20mm. Also, it recommends using support structures and advanced support settings to reduce printing failures when peeling the models off of the bottom of the resin tank. Remember that material flexibility depends on model structure and thickness. If you print dense parts, you will benefit from a good impact resistance while losing pliability. Read on for additional information.

When creating a flexible part, you should always print it in its final shape, just like this Flexible-made watch band.

Resin features

Flexible resin supports a print resolution of either 100 and 50 microns. It comes in 1L cartridges.

It features an elongation of up to 80%, a tensile strength of 7.7–8.5 MPa, and a hardness of 80–85A.


Technical specs

When post-cured, the resin features:

  • Ultimate Tensile Strength: 7.7 - 8.5 MPa
  • Elongation at Failure: 75 - 85 %
  • Compression Set: 0.40 %
  • Tear Strength: 13.3 - 14.1 kN/m
  • Shore Hardness: 80 - 85 A
  • Vicat Softening Point: 230 °C



Flexible printed parts require post-curing. First, you have to wash them in IPA and wait until they are completely dry. Then, you can post-cure them. On the company website, you will find all the information you might require, including material datasheet, cure time and settings.



Formlabs Flexible Resin is available in black.

For some resins, color availability might change. In case of any questions, please get in touch.
