This study investigated the feasibility of fabricating self-lubrication material using fused deposition modelling (FDM) technology, focusing on the influence of printing parameters on tribological performance. Experiments were conducted using PA and ABS materials, with varying printing speed, infill density, and layer height across four levels. The research established regression equations and fitted curves to describe the relationship between printing parameters and the coefficient of friction (CoF). Validation experiments demonstrated the reliability of the models, with errors within 10%. The results indicate that reducing printing speed and increasing infill density enhance surface quality, with infill density exerting a more significant effect. The influence of layer height on surface quality depends on the printer characteristics, making precise quantification challenging. Additionally, this study confirms that resin-based samples produced via FDM exhibit self-lubricating potential. These findings contribute to the optimization of FDM-printed structures by balancing surface quality and tribological performance.
本研究探讨了使用熔融沉积建模（FDM）技术制造自润滑材料的可行性，重点关注打印参数对摩擦学性能的影响。使用PA和ABS材料进行实验，在四个水平上改变打印速度、填充密度和层高。该研究建立了回归方程并拟合曲线，以描述打印参数与摩擦系数（CoF）之间的关系。验证实验证明了模型的可靠性，误差在10%以内。结果表明，降低打印速度和增加填充密度可提高表面质量，其中填充密度的影响更为显著。层高对表面质量的影响取决于打印机特性，难以进行精确量化。此外，本研究证实通过FDM生产的树脂基样品具有自润滑潜力。这些发现有助于通过平衡表面质量和摩擦学性能来优化FDM打印结构。
