Abstract Fused deposition modeling (FDM) 3D printing is widely utilized for producing thermoplastic components with functional purposes. However, the inherent mechanical limitations of pure materials necessitate enhancements in their characteristics when employed certain applications. One strategy addressing this challenge involves incorporation reinforcement materials, such as carbon fiber (CF), within matrix. This approach leads to creation fiber-reinforced polymer composites (CFRPs)...

Abstract Three-dimensional (3D) printing settings allow the existence of differently filled sections together within a piece. That means use inhomogeneous internal material structure. Knowing load capacity that 3D printed plastic parts can withstand leads to reduction filling degree, thus amount used in certain places. This approach has two advantages during production: (i) less and (ii) reduced manufacturing time, both being cost-reducing factors. The present research aims find optimal...
