When To 3D Print With Kevlar

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.

Application Spotlight

Dixon Valve prints Kevlar-reinforced grippers for an industrial robot that transfers fittings between machining centers. Kevlar's toughness combined with its low density make for lightweight jaws that can withstand repeated clampings.


What is Kevlar?

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.
