  1. 1. Crucial Parameters for Additive Manufacturing of Metals : A Study in Quality Improvement

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM); KTH/Skolan för industriell teknik och management (ITM)

    Författare :Lina Berglund; Filip Ivarsson; Marcus Rostmark; [2019]
    Nyckelord :Additive manufacturing; Production parameters; Sandvik; Quality improvement; Selective laser melting; Powder bed fusion; Process control;

    Sammanfattning : Production by Additive Manufacturing creates opportunities to make customized products in small batches with less material than in traditional manufacturing. It is more sustainable and suitable for niche products, but entails new production demands to ensure quality. LÄS MER

  2. 2. EB-PBF additive manufacturing of Alloy 718 : Effect of shot peening on surface characteristics and high temperature corrosion performance

    Magister-uppsats, Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och Maskinteknik

    Författare :Venkataramanan Mohandass; [2019]
    Nyckelord :Alloy 718; additive manufacturing; electron beam-powder bed fusion; surface engineering; shot peening; high temperature corrosion;

    Sammanfattning : There is an upsurge of research interest on Alloy 718 additively manufactured (AM) by electron beam powder bed fusion (EB-PBF) technique in aero and land-based gas turbine engines. However, the surface quality of the manufactured components has always been a major challenge. LÄS MER

  3. 3. Möjligheter för produktion med additiv tillverkning : - En fallstudie

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för handel och företagande

    Författare :Shannon Sarlak; [2019]
    Nyckelord :Additive manufacturing; 3D printing; Traditional manufacturing; Service elements; AM process; Additiv tillverkning; 3D printer; Traditionell tillverkning; Leveransserviceelement; AM processer;

    Sammanfattning : Background: Additive manufacturing is a manufacturing process that has for the past 30 years been used substantially within the branch of industry. By adding material layer-by-layer, an object will be designed, and this method is called 3D-printing. LÄS MER

  4. 4. FrankZlicer : Direct slicing using arcs

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för data- och systemvetenskap

    Författare :Johan Franzén; [2019]
    Nyckelord :FDM; Additive Manufacturing; 3D-printing; CAM; STEP; G-Code; Arc; Slicer;

    Sammanfattning : 3D printing a CAD modelnormally requires conversion into a polygon mesh, usually an STL-file, in orderto be able to load the model in the slicer. This conversion destroys roundsurfaces and replaces them with flat surfaces. Slicing a polygon mesh resultsin one or more polygons, consisting of a number of straight lines. LÄS MER

  5. 5. Prototype manufacturing of microwave components using plastic 3D printing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Björn Malmquist; [2019]
    Nyckelord :;

    Sammanfattning : The ability to easily customize and produce specialized MW-components for research and industry is a real challenge and the need is identified, as standardized parts have limited use and can limit design freedom. This study aims at exploring if there are simple ways to manufacture rectangular X-band waveguides with operating frequency of 8-12GHz with novel polymer additive manufacturing and chemical metal deposition that can match Computer Numerical Control (CNC) manufactured rectangular metal waveguides in performance.
