Powder bed-based additive manufacturing has become increasingly important for industrial applications. In the light of this, qualitative considerations such as the geometrical accuracy, the resulting mechanical properties, and the surface quality of additively manufactured parts must be taken into account. Optical measuring techniques such as confocal laser scanning microscopy, fringe projection and focus variation as well as profilometers are evaluated here, to determine the surface quality of powder bed-based manufactured parts. Even though these surface evaluation methods are established commercially, no standardized measuring procedure has yet been established. Within an experimental study the validity and accuracy of surface measurement methods are evaluated below, taking the limitations of each measurement system and the comparability of areal surface textures into account. The examinations are carried out with the powder materials EN-AW2024, Ti-6V-4Al and PA12, which are ...

增材制造的粉末床基聚合物和金属零件的表面评估的测量程序

基于粉末床的增材制造在工业应用中变得越来越重要。鉴于此，必须考虑定性因素，例如几何精度，所得机械性能以及增材制造零件的表面质量。本文评估了共聚焦激光扫描显微镜，条纹投影和聚焦变化以及轮廓仪等光学测量技术，以确定基于粉末床的制造零件的表面质量。即使这些表面评估方法是商业上建立的，但尚未建立标准化的测量程序。在一项实验研究中，下面评估了表面测量方法的有效性和准确性，考虑到每种测量系统的局限性以及面表面纹理的可比性。检验是使用粉末材料EN-AW2024，Ti-6V-4Al和PA12进行的，它们是...
