摘要整理
聚乳酸（PLA）复合材料作为熔融沉积成型（FDM）3D打印的常用耗材，其性能优化具有重要意义。本研究通过引入碳纤维（CF）来增强PLA复合材料的综合力学性能和热稳定性，并分析了FDM工艺参数对复合材料力学性能的影响规律。研究结果表明，添加5 wt.%碳纤维能显著提升PLA复合材料的刚度和综合力学性能。通过单因素分析，确定了影响PLA复合材料拉伸强度的工艺参数优先级顺序为：打印层厚、热床温度、打印速度和喷嘴温度。在优化工艺条件下，即层厚0.1 mm、热床温度60 °C、打印速度40 mm/s、喷嘴温度215 °C的组合参数下，获得了最优的拉伸强度。该研究为碳纤维增强PLA复合材料在FDM工艺中的应用提供了工艺参数指导，对提高3D打印制件的性能具有实际指导意义。
