Resin Family

Flexible and Elastic

Replace outsourcing and molding of silicone, urethane, and rubber parts. With Formlabs 3D printers, it’s possible to produce flexible parts in-house in a matter of hours using our family of Flexible and Elastic Resins.

Ideal for:

  • Consumer goods prototyping
  • Compliant features for robotics
  • Medical devices and anatomical models
  • Special effects props and models

Flexible 80A

Hard Flexible Prototypes

Flexible 80A Resin is the most stiff soft-touch material in our library of Flexible and Elastic Resins, with an 80A Shore durometer to simulate the flexibility of rubber or TPU. Balancing softness with strength, Flexible 80A Resin can withstand bending, flexing, and compression, even through repeated cycles.

Handles, grips, and overmolds
Cushioning, damping, and shock absorption
Seals, gaskets, and masks
Cartilage, tendon, and ligament anatomy

Which Material Is Right for You?

Trying to choose a material within our Flexible and Elastic family? A good place to start is the Shore durometer, which represents how soft and flexible your part will feel. A higher durometer indicates a stiffer material.

Elastic Family Picture
Elastic Resin in Action

“We had been looking for a softer material with higher elongation for prototyping of grips and frame protection pieces. Until now we were urethane casting these soft parts in 3D printed molds. The parts we have printed in Elastic Resin simulate 50-60A TPU very well. Printing these parts directly will be a big cost and time saver. Elastic Resin is a great addition to our material library.”

-Jeremy Mikesell, Engineering Manager, Research at Cycling Sports Group

Summary

Flexible and Elastic Resins

The family of Flexible and Elastic Resins have many shared applications. Identifying the best material for a specific use case involves understanding your design constraints and the key tradeoffs between the materials.

Handling & Safety

Handling & Safety

Resin should be handled with care. Proper handling will ensure safe printing and efficient use. Our resins have been designed to be similar or safer to handle as other household chemicals or adhesives. Formlabs materials do not contain volatile solvents so special ventilation is not required. Skin contact should be avoided.

The Safety Data Sheets (SDS) are up to date for every resin product and follow the latest government guidelines. Always consult the SDS as the primary source of information to understand safety and handling of Formlabs materials. For more information about handling resin, learn more tips for resin maintenance in our Help Center.
