Material extrusion is one of the most widespread additive manufacturing processes because of its low-cost implementation and its flexibility in design. In this study, integrated digital image correlation is used for the identification of constitutive parameters of two configurations of acrylonitrile butadiene styrene (ABS) samples. It is shown that an isotropic elastoplastic model calibrated from one single edge notched tension specimen described correctly the behavior of 3D printed ABS parts independently of the internal infill strategy.

3D打印丙烯腈丁二烯苯乙烯结构的弹性各向异性

材料挤压是最广泛使用的增材制造工艺之一，因为其实施成本低且设计灵活。在这项研究中，集成的数字图像相关性用于识别丙烯腈丁二烯苯乙烯 (ABS) 样品的两种配置的本构参数。结果表明，从一个单边缺口拉伸试样校准的各向同性弹塑性模型正确地描述了 3D 打印 ABS 零件的行为，而与内部填充策略无关。
