【 摘 要 】

In many areas of application the DMLS-technology emerges as an alternative solution compared to conventional manufacturing methods. This favorable trend of making metal parts is reinforced by the use of one-component powder materials identical to series materials. This again results in new development and application potentials. However the DMLS-parts do not show consistent material properties in comparison to conventionally made parts. This also leads to limited acceptance by industry and research. An exact description (proof) of material properties of DMLS-parts becomes more and more important by the fact that these technologies are used for producing end-products and with it the anisotropic structure of DMLS-parts plays a significant role. For this reason extensive strength analysis (static and dynamic) were carried out by the RTC-Duisburg depending on manufacturing position and orientation, surface finish and different exposure strategies. In this talk well-chosen results of our investigation are presented.
