  1. 1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder

    Kandidat-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Johannes Lövhall; [2024]
    Nyckelord :Process parameter optimisation; Waspaloy; Laser-Directed Energy Deposition with Powder;

    Sammanfattning : 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.
