When To 3D Print With Carbon Fiber

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

Application Spotlight

Haddington Dynamics is a company that developed Dexter, a 3D printed robotic arm made almost entirely out of Markforged parts. Reinforced with continuous carbon fiber filament material, the arm is stiff and lightweight enough for the robot to have a precision of 50 microns (about 0.002″).

FAQ

What is carbon fiber?

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 fiber?

Carbon fiber has a flexural strength of 470 MPa (68 ksi) which is 20% higher than the yield strength of 6061 aluminum. Its tensile strength is 700 MPa (102 ksi), more than twice the ultimate tensile strength of aluminum. To learn more about carbon fiber material properties, check out the data sheet.

How much does carbon fiber filament cost?

A 50cc spool is $150 and a 150cc spool is $450.
