Kevlar® Fibre

What is Kevlar® fibre?

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

When should I 3D print with Kevlar® fibre?

Kevlar® is best used in parts that need to be able to withstand blows. Its low density and high durability make it a great option for applications that require a lot of movement or are associated with production parts.

Reducing changeover time and increasing plant throughput with Markforged technology

There are now 53 unique printed parts on the pad handling machine, including fuse covers, end effector laser sensor brackets, mechanical covers, stop dampers, motor brackets and more.

“People were blown away by the overall quality; they never thought they’d see printed parts being put on machinery that’s actually going to be used in a production manufacturing environment.”

Impact resistance

Kevlar® is 8x more impact resistant than ABS while remaining 15–20% lighter than our other reinforcement fibres.


What is Kevlar® material? Kevlar® is a synthetic fiber developed and produced by DuPont. Known 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.
