Abstract
Due to the limited amount of resources, the consequent application of efficient lightweight design is increasingly getting important. Especially in case of mesoscopic approaches like lattice structures, SLM technologies are getting more and more applied to produce the complex parts. For calculation and dimensioning of such patterns, existing approaches mainly use the development of a homogenized, anisotropic material model in order to describe the behavior of respective structures. This procedure has limitations concerning the load-adapted optimization of the composition. For this reason, a new approach for the calculation, dimensioning and optimization of lattice structures is getting introduced. Therefore, investigations concerning an ideal course of the pattern are examined to achieve a correlation between external loads on the respective part and the ideal orientation of the struts.
