The fused deposition modeling (FDM) process fabricates functional as well as non-functional components through a layer-by-layer deposition strategy. Due to the stair-stepping effect, it becomes difficult to print components with smoother surfaces through the FDM process. Hence, there is an enormous demand for the post-processing of the FDM-printed specimens. Laser polishing is an advanced post-processing technique that can smooth the external surfaces of a 3D-printed product without affecting its mechanical and functional characteristics. Hence, the objective of the present work is to investigate the influence of laser polishing on the surface roughness, tribological behavior, hardness, impact, and tensile strength of the acrylonitrile styrene acrylate (ASA) samples fabricated by the FDM technique. The optimal laser polishing parameters are identified as laser power of 9 W, laser beam diameter of 150 μm, and laser scanning speed of 150 mm/s. The surface roughness (Ra) of the laser-polished ASA samples was minimized by ~ 71.35%, and a significant improvement in hardness (~66.9%), impact strength (~18.02%), and tensile strength (~7.1%) was noticed. The wear rate of laser-polished samples was reduced by ~ 64.2%. The results proved that laser polishing could be an effective way for the post-processing of FDM-printed components.

熔融沉积建模 (FDM) 工艺通过逐层沉积策略制造功能性和非功能性组件。由于阶梯效应，通过 FDM 工艺打印表面更光滑的组件变得困难。因此，对 FDM 打印样本的后处理有巨大的需求。激光抛光是一种先进的后处理技术，可以使 3D 打印产品的外表面光滑，而不影响其机械和功能特性。因此，本工作的目的是研究激光抛光对 FDM 技术制造的丙烯腈苯乙烯丙烯酸酯 (ASA) 样品的表面粗糙度、摩擦学行为、硬度、冲击力和拉伸强度的影响。确定最佳激光抛光参数为激光功率9 W、激光束直径150 μm、激光扫描速度150 mm/s。激光抛光 ASA 样品的表面粗糙度 (Ra) 最小化了约 71.35%，硬度 (约 66.9%)、冲击强度 (约 18.02%) 和拉伸强度 (约 7.1%) 显着提高。激光抛光样品的磨损率降低约 64.2%。结果证明，激光抛光可能是 FDM 打印部件后处理的有效方法。
