In recent years, additive manufacturing technology, particularly in plastic component fabrication, has gained prominence. However, fundamental modelling of the influence of materials like ABS, PC, and PLA on tribological properties in fused deposition modeling (FDM) remains scarce, particularly in non-lubricated, oil-lubricated, and grease-lubricated modes. This experimental study systematically investigates the effects of material type, lubrication method, layer thickness, and infill density on FDM component tribology. A tribology analysis is conducted using a TRB3 tribometer. The results indicate a coefficient of friction (CoF) range between 0.04 and 0.2, generally increasing and decreasing with layer thickness and filler density. The lubrication impact hinges on the material surface texture. The study models the intricate relationships between these variables via full-factor analysis, showing a strong alignment between the modelled and measured friction coefficients (an average error of 3.83%). Validation tests on different materials affirm the model's reliability and applicability.
近年来，增材制造技术，尤其是在塑料部件制造方面，已变得日益重要。然而，关于诸如ABS、PC和PLA等材料对熔融沉积建模（FDM）中摩擦学性能影响的基础建模仍然很少，特别是在非润滑、油润滑和脂润滑模式下。这项实验研究系统地调查了材料类型、润滑方法、层厚和填充密度对FDM部件摩擦学的影响。使用TRB3摩擦磨损试验机进行摩擦学分析。结果表明，摩擦系数（CoF）范围在0.04至0.2之间，通常随层厚和填充密度而增减。润滑效果取决于材料表面纹理。该研究通过全因子分析对这些变量之间的复杂关系进行建模，结果显示建模摩擦系数与测量摩擦系数之间有很强的一致性（平均误差为3.83%）。对不同材料的验证测试证实了该模型的可靠性和适用性。
