摘要: Abstract This study focuses on the characterization of additive manufacturing technology based composite filament fabrication (CFF). CFF utilizes a similar method layer by printing as fused but is also capable reinforcing parts with layers various continuous fibers into polymer matrix. Due to orthotropic characteristics fabrication, 3D printed may present different mechanical behavior under orientations stress. Furthermore, technologies such allow range configurations fabricate and reinforce parts. In this study, polyamide 6 (PA6) reinforced carbon fiber was conducted design experiment statistical method, investigate effect reinforcement pattern, distribution, print orientation percentage compressive flexural properties. stronger than conventional technologies. Maximized response achieved 0.2444 Carbon Fiber volume ratio, concentric equidistant configuration, resulting in modulus 2.102 GPa stress at proportional limit 53.3 MPa. 0.4893 perpendicular applied force, 14.17 GPa 231.1 MPa.
