Elastic Resin

for Soft Flexible Parts

Elastic Resin is an elastomeric material designed for applications requiring high elongation and high energy return. Use Elastic Resin for parts that will bend, stretch, compress, and hold up to repeated cycles without tearing. Elastic is transparent, which makes it well suited for medical models for simulation or education.

Elastic Resin prints at 100 microns. Resin Tank LT is required for printing with Elastic Resin.

Recommended for:

  • Wearables and consumer goods prototyping
  • Medical models and devices
  • Compliant features for robotics
  • Special effects props and models

Not suitable for:

  • Parts requiring high surface detail
  • Parts that need to hold a particular structure or shape
  • Parts requiring high dimensional accuracy


Comparison with Other Materials

Elasticity is the ability of an object or material to resume its normal shape after being stretched or compressed. Elastic Resin is designed to “bounce back” and return to its original shape quickly.


Durometer is the hardness of a material. Elastic Resin has a lower durometer than other Formlabs resins, making it suitable for prototyping parts normally produced with silicone. Elastic also has a higher tear strength than comparable materials, making it capable of repeated cycles of use.
