In three-point bending, our 3D printed carbon fiber is 8x stronger than ABS and 20% stronger than the yield strength of aluminum.
3D printed carbon fiber is 25x more rigid than ABS and 2x more rigid than the rest of Markforged’s reinforcement fibers.
Compared to 6061 aluminum, 3D printed carbon fiber has a 50% higher strength-to-weight ratio in flexure and 300% higher in tension.
Carbon fiber material is strong enough to replace aluminum at half the weight; use it when you want superior stiffness and minimal deflection.
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.
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.
