Additive manufacturing (AM) technologies are recognized as promising new approaches for the production of industrial goods. One of the major drawbacks, however, is the surface quality of parts prepared by AM. In the present paper, the potential of applying classical surface technology to efficiently improve the surface properties of AM products is explored. The surface properties of parts produced by different AM technologies were investigated and showed rather large variations between various spots at the surface. Low‐pressure plasma, as well as flame treatment, were found to provide a good activation also of the porous surfaces of parts prepared by selective laser sintering of PA12 (polyamide). Lacquering was found to tremendously reduce the roughness of AM products. The best results were obtained by the combination of lacquering and polishing of lacquers, which are optimized for polishing.

增材制造的表面技术

增材制造（AM）技术被公认为是有前途的工业产品生产新方法。但是，主要缺点之一是AM制备的零件的表面质量。在本文中，探索了应用经典表面技术来有效改善AM产品表面性能的潜力。研究了通过不同的增材制造技术生产的零件的表面性能，并显示了表面各个斑点之间的较大差异。发现低压等离子体以及火焰处理还可以对通过选择性激光烧结PA12（聚酰胺）制得的零件的多孔表面提供良好的活化作用。发现漆可以极大地降低AM产品的粗糙度。
