1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder
University essay from Högskolan Väst/Institutionen för ingenjörsvetenskapAbstract : Material utilisation is of importance in the manufacturing industry formaking the most of each material, minimising waste and increasing cost-effectiveness. In this thesis, samples of Waspaloy built with the method of L-DED-P has been analysed in order to investigate how process pa-rameters influence the build quality and geometrical accuracy in as-builtobjects.
