Abstract
The paper reports some results of experimental study on the effect of 3D-printing on the linear and nonlinear elastic properties of ABS polymer specimens manufactured in the form of thin filaments with 100% filling. The initial and 3D-printed ABD polymer specimens were studied by the static and Thurston–Bragger methods. Linear and nonlinear Young’s moduli and second-order nonlinear acoustic parameters were determined for several loading–unloading cycles of a specimen. It has been shown that the selected 3D-printing mode does not almost change the strength characteristics of ABS polymer, and its plastic characteristics even become slightly better. It has been revealed that mechanical loading has different effects on the nonlinear parameter of the initial and 3D-printed specimens. For the 3D-printed specimen, the nonlinear parameter is observed to decrease with increasing load.
摘要--本文报告了三维打印对以 100%填充的细丝形式制造的 ABS 聚合物试样的线性和非线性弹性性能影响的一些实验研究结果。通过静态和 Thurston-Bragger 方法研究了初始 ABD 聚合物试样和三维打印 ABD 聚合物试样。确定了试样多次加载-卸载循环的线性和非线性杨氏模量以及二阶非线性声学参数。结果表明，所选的三维打印模式几乎不会改变 ABS 聚合物的强度特性，其塑性特性甚至略有改善。研究发现，机械加载对初始试样和 3D 打印试样的非线性参数有不同的影响。对于三维打印试样，非线性参数随着载荷的增加而减小。
