Abstract

3D printed CF/PA6+PA11 filaments are created from a blend of BASF's polyamide 6 (PA6), Arkema's polyamide 11 (PA11), and carbon fibers from Toray (Japan). This study focuses on evaluating the blend ratios of PA6, PA11, and the composite ratios of the blend with carbon fibers in the production of 3D printed filaments. Key technical parameters such as tensile strength, flexural strength, and impact strength were measured to assess mechanical performance under filament fabrication conditions. The study determined that a blend ratio of 70:30 for PA6:PA11 provides the best compatibility. Based on the PA6 and PA11 blend, the 3D printed CF/PA6-PA11 filament achieved suitable mechanical properties with component ratios of PA6, PA11, short carbon fibers (≤ 0.3 mm), and long carbon fibers (0.3 mm – 1 mm) at 49%, 21%, 20%, and 10%, respectively.
