  1. 6. Fabricability of a high alloy tool steel produced with LPBF, with a focus on part geometry

    University essay from Karlstads universitet

    Author : Zulfaqar Abdelamir; [2021]
    Keywords : Addtive Manufacturing; Laser Powder Bed Fusion; High alloy Cold Work Tool Steel; Addtiv Tillverkning; LPBF; Höglegerat kallbearbetningsstål;

    Abstract : Additive manufacturing (AM) is a promising manufacturing process that provides that ability to fabricate components with complex geometries with relatively low lead times compared to other manufacturing processes. This allows for more freedom of design, as prototypes can easily be produced throughout the development process. READ MORE
