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

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

    Sammanfattning : 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. LÄS MER

  3. 22. Optimization of laser powder bed fusion process parameters for 316L stainless steel

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

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

    Sammanfattning : 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.

    Master-uppsats, Linköpings universitet/Produktrealisering; Linköpings universitet/Maskinkonstruktion

    Författare :Morgan Waagaard; Johan Persson; [2020]
    Nyckelord :AM; Additive Manufacturing; 3D printing; DfAM; Design for Additive Manufacturing; SLM; Selective Laser Melting; L-PBF; Laser Powder Bed Fusion; Topology Optimization; Design Optimization; titanium alloy; Suspension Systems; Automotive Applications; Racing; Motorcycle; Motorbike; Moto Racing; Roadracing; Additiv tillverkning; Additiv Tillverkningsteknik; Friformsframställning; Topologioptimering; Designoptimering; Titanlegering; Hjulupphängning; Fjädringssystem; Fordonsteknik; Fordonsapplikationer; Motorcykel; Motorcykelracing; Motorsport;

    Sammanfattning : This project was conducted as a case study at Öhlins Racing AB, a manufacturer of suspension systems for automotive applications. Öhlins usually manufacture their components by traditional methods such as forging, casting, and machining. LÄS MER

  5. 24. Process and microstructure development of a LPBF produced maraging steel

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Kenny Johansson; [2020]
    Nyckelord :Maraging steels; additive manufacturing; Laser Powder Bed Fusion; LPBF; additiv tillverkning; maråldringsstål; pulverbädd;

    Sammanfattning : Additive manufacturing (AM) has the possibility of producing complex-shaped components which can not be produced by conventional manufacturing methods. This gives the opportunity for designers to freely think outside the design spectra which is otherwise limited by conventional manufacturing methods. LÄS MER

  7. 25. Qualification process development for metal additive manufacturing - A study for the establishment of additive manufacturing at Alfa Laval

    Master-uppsats, Lunds universitet/Innovation

    Författare :Klara Svensson; Josefine Laurén; [2020]
    Nyckelord :additive manufacturing; qualification process; laser powder bed fusion; metal AM; 3D-printing; qualification of AM; additiv tillverkning; kvalificeringsprocess; laser-pulverbäddsfusion; metall-AM; 3D-printning; kvalificering av AM; Technology and Engineering;

    Sammanfattning : Den additiva tillverkningsprocessen och kvalificeringen av komponenter i metall är komplex och tillverkningsmetoden är inte ännu fullständigt förstådd. Syftet med detta examensarbete är därför att förvärva kunskap om kvalificeringsprocesser kopplade till additiv tillverkning i metall och att utveckla en hållbar kvalificering för additivt tillverkade komponenter hos Alfa Laval.
