What is Carbon-Fibre?

The stiffest and strongest fibre with the highest strength to weight ratio.

When should I 3D print with Carbon-Fibre?

Carbon fiber material is strong enough to replace aluminum 6061 at half the weight; use it when you want superior stiffness and minimal deflection.

First CE-certified 3D printed part

Wärtsilä is a leading global supplier of intelligent technologies and system solutions for the shipping and energy markets, with a product portfolio ranging from motors to drive and renewable energies. The tool made of onyx with carbon continuous fiber has undergone various tests and inspections, resulting in the first 3D-printed, CE-certified hoisting tool.

“The best thing about 3D printing is that any design can be printed anywhere and at any time, even on the cargo ships that Wärtsilä helps maintain and service.”

Juho Raukola, additive manufacturing manager

Flexural Strength

In three-point bending, our 3D printed carbon fiber is 8x stronger than ABS and 20% stronger than the yield strength of aluminum.


What is Carbon-Fibre?
Carbon fiber is a thin filament made up of carbon atoms organized into a crystalline structure. Because of its very high stiffness and strength it is widely used in the aerospace and automotive industries.

How strong is Carbon-Fibre?
Carbon fiber has a flexural strength of 540 MPa (78.3 ksi) which is more than 6 times greater than parts printed in only Onyx. It’s tensile strength is 800 MPa (116.0 ksi) more than twice the ultimate tensile strength of aluminum 6061. To learn more about carbon fiber material properties, check out the data sheet.

What does the carbon fibre filament cost?
A 50cc spool costs £120.00 excl. VAT and a 150cc spool is £360.00 excl. VAT.
