熔融沉积成型技术可以制造任何复杂的几何结构和内部结构，在生物医药、制造、航空航天、汽车、工业、建筑等行业得到了广泛的应用。本研究的目的是在四种加载条件(拉伸、压缩、弯曲和热变形)下对FDM的聚乳酸(PLA)和聚对苯二甲酸乙二醇酯(PETG)材料进行表征，以获得不同打印温度和速度的数据。结果表明，聚乳酸和PETG材料表现出明显的拉伸和压缩不对称性。结果表明，在较高的印刷温度下，聚乳酸和聚乙三醇酯的力学性能(拉伸、压缩和弯曲)都有所提高，但印刷速度对聚乳酸和聚乙三醇酯的影响不同。此外，聚乳酸的力学性能高于PETG，但热变形性能则相反。上述研究结果将对致力于聚合物和fdm技术以实现可持续发展的研究人员有很大帮助。
Fused Deposition Modeling (FDM) can be used to manufacture any complex geometry and internal structures, and it has been widely applied in many industries, such as the biomedical, manufacturing, aerospace, automobile, industrial, and building industries. The purpose of this research is to characterize the polylactic acid (PLA) and polyethylene terephthalate glycol (PETG) materials of FDM under four loading conditions (tension, compression, bending, and thermal deformation), in order to obtain data regarding different printing temperatures and speeds. The results indicated that PLA and PETG materials exhibit an obvious tensile and compression asymmetry. It was observed that the mechanical properties (tension, compression, and bending) of PLA and PETG are increased at higher printing temperatures, and that the effect of speed on PLA and PETG shows different results. In addition, the mechanical properties of PLA are greater than those of PETG, but the thermal deformation is the opposite. The above results will be a great help for researchers who are working with polymers and FDM technology to achieve sustainability.
