Kevlar is 8x more impact resistant than ABS while remaining 15–20% lighter than our other reinforcement fibers.
In three-point bending, 3D printed Kevlar is 3x stronger than ABS and 6x stronger than nylon.
3D printed Kevlar is 12x more rigid than ABS and 30x more rigid than nylon.

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
- End use parts
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.
