   Master-uppsats, Linköpings universitet/Konstruktionsmaterial

   Författare :Ida Ljusell; [2023]
   Nyckelord :Additive manufacturing; AM; 3d printing; titanium; process characterisation; electron beam powder bed fusion;

   Sammanfattning : Additive manufacturing (AM) are manufacturing methods where components are produced by adding material layer by layer which allows for a high freedom of design as well as little or no material waste compared to conventional manufacturing methods. Despite the many benefits of AM there are still problems concerning the quality of the produced material. LÄS MER
