Gears are often exposed to heat and they can be deformed. Carbon fibers reinforced polyamide is the best choice for this application, this material has a very high stiffness compared to other FDM material and a high transition temperature which assure thermal stability.
This model was 3D printed as part of a Bachelor degree thesis work by the students of Material Engineering and nanotechnology at Polimi: El Achak Hakim, Ghedini Lorenzo, Giunta Angela, Guastalla Mattia, Lavazza Jacopo, Mascheroni Daniele.
