This paper presents ex-ante examination of advanced polymer materials to detect defects and define and minimize the potential failure of novel polymer products before they arise. The effect of build directions on the properties of dumbbell-shaped specimens obtained by three-dimensional printing from polylactide and polylactide/polyhydroxyalkanoate commercial filaments was investigated, as well as the hydrolytic degradation of these specimens at 50 °C and 70 °C. Taking into account previous studies, we have found further dependences of the properties of 3D printed species before and during abiotic degradation from the orientation of printing. The initial assumption that only the contact time with the 3D printer platform leads to an increase in the crystalline phase during printing turned out to be insufficient. Further investigations of individual parts of the dumbbell-shaped specimens showed that the size of the specimens' surface in contact with the platform also affected the structural ordering of the material.

本文介绍了事前检查先进的聚合物材料以发现缺陷，并在新的聚合物产品出现之前确定并最大程度地减少潜在的故障。研究了构建方向对通过三维印刷从聚丙交酯和聚丙交酯/聚羟基链烷酸酯商业长丝获得的哑铃形标本的性能的影响，以及这些标本在50°C和70°C下的水解降解。考虑到以前的研究，我们发现非生物降解之前和过程中3D打印物种的特性进一步依赖于打印方向。最初的假设是仅与3D打印机平台的接触时间会导致打印过程中结晶相的增加，这是不充分的。
