Abstract

Research and manufacturing of 3D printing fibers using polyamide 6 (PA6) polyamide and short carbon fibers are conducted, and these fibers are utilized for printing samples. The study involves the utilization of BASF's 6 polyamide and Toray's (Japan) carbon fiber with a length of less than 300μm to produce 3D printed fibers. The mechanical properties of various fiber processing conditions are assessed by measuring tensile strength and bending strength. The tensile strength of 3D printing fibers is determined by analyzing printing samples, which allows for the evaluation of mechanical properties under various printing settings. The optimal conditions for achieving the highest strength in CF/PA6 3D printing fibers are a melting temperature of 270 ^oC, a screw speed of 50 rpm, and a pull speed of 5 cm/s. The optimal conditions for 3D printing in survey settings involve achieving the maximum pull resistance by using infill density of 50%, concentric pattern, wall thickness of 2 layers, and a layer height of 0.1 mm.
