Kevlar Filament

Kevlar® is tough, lightweight material, and can bend further than any other fiber, making it ideal for 3D printing.

When To 3D Print With Kevlar Material

Kevlar is best utilized in parts that will take a beating. Its low density and high durability make it a great option for applications involving a lot of motion or interfacing with production parts.

  • End effectors
  • Cradles
  • Soft jaws
  • End use parts

 

What is Kevlar material?

Kevlar is a synthetic fiber developed and produced by DuPont. Know for its light weight and toughness, it is traditionally used in products such as tires, sails, rope, and protective equipment. Kevlar is an excellent material for 3D printing.
