In the field of thermal separation technology, additive manufacturing has become increasingly important. 3D-printed components are often characterized by computational fluid dynamics simulations. Therefore, the knowledge of contact angles and surface properties are crucial. Materials used for 3D-printed components have so far not been characterized with sufficient precision, which resulted in limited awareness about contact angles. Within this work, surface characterizations of printable materials consisting of stainless steel and polypropylen were performed using atomic force microscopy and contact angle measurements. The interactions of these solid materials with water were investigated. It is shown that the 3D-printing method and the component orientation during the printing process can have a significant influence on the interaction of solid material and liquid.

3D打印材料的接触角和表面形态研究

在热分离技术领域，增材制造变得越来越重要。3D打印的组件通常以计算流体动力学仿真为特征。因此，接触角和表面特性的知识至关重要。迄今为止，用于3D打印组件的材料尚未以足够的精度进行特征化，这导致人们对接触角的了解有限。在这项工作中，使用原子力显微镜和接触角测量对由不锈钢和聚丙烯制成的可印刷材料进行了表面表征。研究了这些固体材料与水的相互作用。
