Formlabs Elastic 50A SLA Resin

Whether you’re optimizing your manufacturing process, rapidly iterating through designs, or assessing form, fit, and function, Formlabs Engineering Resins are formulated to withstand extensive testing and perform under stress.

Formlabs softest Engineering Resin, this 50A Shore durometer material is suitable for prototyping parts normally produced with silicone. Choose Elastic 50A Resin for parts that will bend, stretch, compress, and hold up to repeated cycles without tearing, and spring back quickly to their original shape.

The “50A” in the name represents the material’s Shore durometer. If you need a more stiff flexible material, try Flexible 80A Resin

Printing Settings


Print Resolutions* 100 microns.
Post Curing Required
Tank Resin Tank LT (Form 2) or Resin Tank V2 (Form 3) are required for printing with Elastic 50A resin.

*Layer height compatibility can depend on printer model.

NOTE: Elastic Resin decreases the lifetime of resin tanks. Read more about Resin Tank LT lifetime and Form 3 Resin Tank lifetime.

STORAGE  & Disposal

Formlabs materials require proper storage to maximize the usable lifetime. Light and temperature affect shelf life significantly. For optimal results, follow Formlabs guidelines for storing and handling resins. 

  • Use a different resin tank for each type of Formlabs resin. Cleaning the resin tank to change resins may lead to contamination and print failures.
  • To avoid contamination, do not pour resin back into cartridges.
  • Store resin according to the SDS, away from direct sunlight in a dry, cool, and well-ventilated area.
  • Shake resin containers approximately every two weeks when in storage to keep resins thoroughly mixed.
  • For long-term storage, pour resin into a separate, opaque container from the resin tank. Formlabs recommends wide-mouth opaque HDPE or polypropylene bottles. Containers made of other materials may leak.
  • Dispose of liquid resin (whether liquid, dissolved in IPA, or partially cured) and anything contaminated with liquid resin according to environmental regulations.
