The combination of the carbon fiber composite and 3D printing technology can be a powerful approach to produce the high-strength light-weight and complex construction mechanical parts. Compared with the short carbon fiber which has been widely used, application of continuous carbon fiber in 3D printing can undoubtedly better play its good mechanical properties. Usually, complex parts include multiple independent contours, which lead to discontinuous paths in the 3D printing process.For the continuity characters of the continuous carbon fiber composite, it needs to be sheared off due to the dis...
