    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :André Leo; [2022]
    Nyckelord :Powder rheology; AM; Additive manufacturing; BPF; Powder bed fusion; SLM; Selective laser melting; FT4 powder rheometer; Compressibility; Permeability; Aeration; Pulver reologi; AM; Additiv tillverkning; BPF; Pulver bed fusion; SLM; Selektiv lasersmältning; FT4 pulver reometer; kompressibilitet; permeabilitet; luftning;

    Sammanfattning : Additive manufacturing with the use of metals have been a steadily increasing field, being able to create products with a higher degree of complexity than traditional processing techniques. SLM is a popular AM process that uses metal powder as feedstock, and one of the key components of this process is the powder rheology. LÄS MER

  3. 2. Characterization of Metal Powders in Electron Beam Powder Bed Fusion : Regarding particle size distribution of the finished part

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Mattias Jerhamre Engström; Saman Sharif Hedås; [2022]
    Nyckelord :;

    Sammanfattning : As the manufacturing industry looks for better ways to create complex parts using sustainable and efficient methods, the additive manufacturing sector is taking a step forward. Additive manufacturing brings with it a large reduction in material used and the complex structures that can be created are not something to overlook. LÄS MER

  4. 3. Improvement and Development of Powder Spreadability Testing

    Master-uppsats, KTH/Materialvetenskap

    Författare :Fabrice Rosala; [2021]
    Nyckelord :;

    Sammanfattning : With rising interest in metal additive manufacturing and, specifically, in powder bed fusion processes, it is essential to understand relevant process parameters and the behavior of powders used in such processes. At the time of writing, the flow behavior of powders is in the spotlight whereas little research into the spreadability of a powder is being conducted. LÄS MER

  5. 4. Evaluating spreadability of metallic powders for powder bed fusion processes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Vignesh Hari; [2020]
    Nyckelord :Additive manufacturing; spreadability; flowability; Additiv tillverkning; spridbarhet; flytbarhet; mätetal;

    Sammanfattning : Additive  manufacturing  technologies  are  widely  used  in  aerospace,  space,  and  turbine industries. Parts can be manufactured directly by selectively adding materials layer-by-layer. A key aspect that is critical to the quality of the final component being manufactured is the powder characteristics. LÄS MER

  7. 5. 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
