  2. 7. Application of X-ray Computed Tomography for Assessment of Additively Manufactured Products

    University dissertation from Örebro : Örebro University

    Author : Amir Reza Zekavat; Örebro universitet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; X-ray computed tomography; Surface roughness;

    Abstract : Additive Manufacturing (AM) is a novel method for fabricating parts from three-dimensional model data, usually by joining materials in layer upon layer fashion. The freedom of design in this method has resulted in new possibilities for fabrication of parts with complex geometries. READ MORE

  3. 8. Sub-grain structure in additive manufactured stainless steel 316L

    University dissertation from Stockholm : Department of Materials and Environmental Chemistry, Stockholm University

    Author : Yuan Zhong; Stockholms universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Selective laser melting; Electron beam melting; stainless steel; Oxide dispersion strengthened steel; Cellular structure; Nano-inclusions; materialkemi; Materials Chemistry;

    Abstract : The thesis focuses on exploring the sub-grain structure in stainless steel 316L prepared by additive manufacturing (AM). Two powder-bed based AM methods are involved: selective laser melting (SLM) and electron beam melting (EBM). READ MORE

  4. 9. Microstructure and Texture of Additive Manufactured Ti-6Al-4V

    University dissertation from Luleå University of Technology

    Author : Magnus Neikter; Luleå tekniska universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; microstructure; Ti-6Al-4V; texture; Material Mechanics; Materialmekanik;

    Abstract : Additive manufacturing (AM) for metals is a manufacturing process that has increased a lot in popularity last few years as it has experienced significant improvements since its beginning, both when it comes to accuracy and deposition rates. There are many different AM processes where the energy sources and deposition methods varies. READ MORE

  5. 10. Qualification of Metal Additive Manufacturing in Space Industry Challenges for Product Development

    University dissertation from Luleå : Luleå University of Technology

    Author : Christo Dordlofva; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Space industry; Product Development; Qualification; Design for Additive Manufacturing;

    Abstract : Additive manufacturing (AM), or 3D printing, is a collection of production processes that has received a good deal of attention in recent years from different industries. Features such as mass production of customised products, design freedom, part consolidation and cost efficient low volume production drive the development of, and the interest in, these technologies.
