[0002] The entire 3D printing process involves melting plastic in a nozzle and then depositing plastic fibers to form thin layers. Among the many technologies that enable 3D printing, fused deposition is the most basic. It doesn't rely on lasers as a molding energy source, but instead heats and melts various filaments to form a stacked structure.
