Application of 3D printing metal powder technology in the manufacture of components with complex geometries

Abstract

The possibilities of using 3D printing powder technologies for making objects with complex geometries were present-ed. For this purpose, selected examples of elements with different geometries were used, which were built using metal powder methods – DMLS (direct metal laser sintering) / SLM (selective laser melting). Simultaneously, the in-dicated elements concern those areas of industry where 3D printing technology has been widely used in recent years, i.e. maritime and aerospace industries. Also, the metal 3D printing process was characterized by a description of the particular stages of model building. The directions of fur-ther development of the above mentioned 3D printing methods and the areas of possible applications of the 3D printed parts were presented, respectively.
