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
• Soft jaws
• Cradles
• End use parts

Application Spotlight

Dixon Valve 3D 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.
