  1. 21. 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

  3. 22. Fatigue properties of Laser Powder Bed Fusion (LPBF) built 21-6-9 stainless stee

    University essay from Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Author : Jayanth Krishna; [2021]
    Keywords : stainless steels; LPBF; Fatigue; 21-6-9;

    Abstract : Fatigue performance is one of the important mechanical properties which is hindering some of the additive manufacturing build structures. The main objective of this study is to investigate the fatigue life dependence of the 21-6-9 austenitic stainless-steel build using the laser powder bed fusion (LPBF) technique. READ MORE

  4. 23. Corrosion of additively manufactured magnesium alloy WE43 : An investigation in microstructure and corrosion properties of as built samples manufactured with Powder Bed Fusion-Laser Beam

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Clarence Wahman; [2021]
    Keywords : Mangesium; WE43; corrosion; additive manufacturing; biodegradable implants; microstructure; surface roughness; Magnesium; WE43; korrosion; additiv tillverkning; resorberbara implantat; mikrostruktur; ytråhet;

    Abstract : The work presented in this thesis was conducted at Uppsala University and at Swerim AB. The study aims to broaden the knowledge about the corrosion of additively manufactured bioresorbable alloy WE43 in humanlike conditions for future applications. READ MORE

  5. 24. The effect of stripe width, stripe overlap, gas flow, and scan angle on process stability in Laser Powder Bed Fusion (L-PBF)

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Carl Högman; [2021]
    Keywords : Additive Manufacturing; Laser Powder Bed Fusion; Process Stability; Process Parameters;

    Abstract : It is known that altering different processing parameters will yield completely different results in additive manufacturing. Some of the most common ones to alter to increase material quality or to increase productivity are laser power, hatch distance, layer thickness and scan speed. READ MORE

  6. 25. Optimization of laser powder bed fusion process parameters for 316L stainless steel

    University essay from Uppsala universitet/Oorganisk kemi

    Author : William Hahne; [2021]
    Keywords : Additive manufacturing; Stainless steel; 316L; Laser powder bed fusion; Powder bed fusion; Build rate; Powder layer thickness;

    Abstract : The interest for additive manufacturing techniques have in recent years increased considerably because of their association to good printing resolution, unique design possibilities and microstructure. In this master project, 316L stainless steel was printed using metal laser powder bed fusion in an attempt to find process parameters which yield good productivity while maintaining as good material properties as possible.
