| Abstract Scope |
In this work, three different types of Ti6Al4V powder feedstock of different particle size ranges (small, medium and coarse) were utilized to fabricate thin wall lightweight features using laser powder bed fusion additive manufacturing (L-PBF-AM) using different process parameter settings. Thin wall features of varying dimensions from 0.1mm to 0.5mm were fabricated. The resulting sample sets allow for the analysis of the compound powder feedstock-process-geometry-material (PPG-M) characteristics for lightweight features fabricated by L-PBF-AM, which has not been previously explored. Various material characteristics, including porosity, grain size, geometry quality and mechanical properties of the thin wall samples were experimentally determined and analyzed. The results clearly demonstrated the significance of the compound PPG-M relationships for lightweight structures, which calls for further studies to “re-establish” knowledge base for L-PBF-AM materials at small dimension scales. |
