Item type:Publication, Access status: without files , Development of a tree-support software module for PBF-LB/MBy combining simulation and generative design, a software tool was developed that generates individual support structures in the form of trees. The objective is that even users with little experience can manufacture components with efficient support structures using PBF-LB/M. The key element of the method is the use of tree structures whose shape is generated by algorithmic, biological growth using botanical methods. Topology optimization, which has already proven itself in the design of optimal support structures, was used to optimize the support structures of three benchmark parts. The generated trees were then compared to commercially available tree-like supports and block supports using Finite element analysis to simulate the PBF-LB/M process. The simulation also included a stress relief heat treatment and the removal of the part from build plate and supports. Based on the knowledge gained from the numerical assessment of the generated tree supports, the created tool allows the user to generate highly material-usage efficient supports with block support-comparable capabilities without requiring any previous experience of the subject.Publicationtype: Conference Paper64
