5. 4. A comparative study on anapproach to print Industrial Toolsvia Additive Manufacturing for Volume Production from Technical, Economic, and Environmental aspects

   Master-uppsats, KTH/Produktionsutveckling

   Författare :Purav Mukesh Thaker; [2023]
   Nyckelord :;

   Sammanfattning : The thesis explores a path to use Additive Manufacturing as an approach for volume production of Industrial Technique Business Area Tools, addressing the challenges of manufacturing complexity, low volume demand, and quality control for both Atlas Copco Industrial Technique industrial tools (Tool 1 & Tool 2). This study is done in cooperation with Atlas Copco Industrial Technique, comparing the technological, economic, and environmental performance of AM versus the current manufacturing approach from a round bar.
