This study investigates the mechanical properties of ABS parts fabricated via used deposition modeling (FDM) through integrated experimental and numerical approaches. ABS resin was used as the experimental material, and tensile tests were conducted using a universal testing machine. Finite element analysis (FEA) was performed via ANSYS 2021 to simulate stress deformation behavior, with key parameters including a gauge length of 10 mm (pre-stretching) and printing temperature gradients. The results show that the specimen exhibited a maximum tensile force of 7.3 kN, upper yield force of 3.7 kN, and lower yield force of 3.2 kN, demonstrating high strength and toughness. The non-proportional elongation reached 0.06 (6%), and the quantified enhancement multiple of AM relative to traditional manufacturing was 1.1, falling within the reasonable range for glass fiber-reinforced or specially formulated ABS. FEA results validated the experimental data, showing that the material underwent 15 mm of plastic deformation before fracture, consistent with ABS's ductile characteristics.
本研究通过综合实验和数值方法，研究了采用熔融沉积成型（FDM）制造的ABS零件的力学性能。以ABS树脂作为实验材料，使用万能试验机进行拉伸试验。通过ANSYS 2021进行有限元分析（FEA），以模拟应力变形行为，关键参数包括10毫米的标距长度（预拉伸）和打印温度梯度。结果表明，试样的最大拉力为7.3 kN，上屈服力为3.7 kN，下屈服力为3.2 kN，显示出高强度和韧性。非比例伸长率达到0.06（6%），增材制造相对于传统制造的量化增强倍数为1.1，处于玻璃纤维增强或特殊配方ABS的合理范围内。有限元分析结果验证了实验数据，表明材料在断裂前经历了15毫米的塑性变形，这与ABS的韧性特征相符。
