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″).
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 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.
How much does carbon fiber filament cost?
A 50cc spool is $150 and a 150cc spool is $450.
material is compatible with our desktop and industrial series 3D printers.
