A Novel Synchronous Scanning Strategy in Laser Powder Bed Fusion and Effect on Mechanical Properties of Industrial Gears

Abstract

The effect of LPBF process parameter change on production results has been the subject of many studies. In this study, innovative synchronous scanning strategy in LPBF production system and the effect of this scanning strategy on industrial gears are discussed. The scanning strategy obtained by the synchronous use of hatch distance, stripe width, and layer thickness parameters constitutes the innovative aspect of the study. In trial productions, it was observed that the traditional melt pool form changed and the strength increased by 25% in industrial gears produced with this scanning strategy. It is thought that this synchronous parameter change creates a potential for the production of industrial components with reduced weight. The scope of the study consists of parameter studies, LPBF production, material laboratory studies, microstructure, and SEM (scanning electron microscope) examination, and compression test.
