  1. 1. Residual Stress in Additive Manufacturing : Control using orientation and scan strategies

    Författare :Prabhat Pant; Ru Peng; Johan Moverare; Kjell Simonsson; Thomas Niendorf; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Residual stress; Neutron diffraction; FEM; Scan strategies; Build orientations;

    Sammanfattning : Components with complex features that are designed with their function as a core aspect often are not viable to be manufactured with traditional methods. This has been a bottleneck in the past, leading to heavier parts with various sub-assemblies and a significant waste of material. LÄS MER

  2. 2. Additive Manufacturing using Alloy 718 Powder : Influence of Laser Metal Deposition Process Parameters on Microstructural Characteristics

    Författare :Andreas Segerstark; Joel Andersson; Lars-Erik Svensson; Robert Pedersen; Högskolan Väst; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Laser metal deposition; powder; superalloy; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Additive manufacturing (AM) is a general name used for production methodswhich have the capabilities of producing components directly from 3D computeraided design (CAD) data by adding material layer-by-layer until a final component is achieved. Included here are powder bed technologies, laminated object manufacturing and deposition technologies. LÄS MER

  3. 3. Additive manufacturing of fused silica glass

    Författare :Pawel Maniewski; Michael Fokine; Fredrik Laurell; Daniel Milanese; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser cladding; 3d printing; additive manufacturing; glass; fused silica; laser; scattering; silica; Optics and Photonics; Optik och fotonik; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Additive Manufacturing, of both metals and polymers, has seen rapid development in recent years, whereas the progress in glass has been rather slow. Today, glass can be considered the last frontier without a specialized 3D printing method available. LÄS MER

  4. 4. Additive Manufacturing of Ferritic Materials : A Journey from Stainless Steels to High-Entropy Alloys

    Författare :Dennis Karlsson; Ulf Jansson; Martin Sahlberg; Eduard Hryha; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Additive Manufacturing; Laser Powder Bed Fusion; Binder Jetting; Ferritic Stainless Steel; High Entropy Alloy; Mechanical Properties;

    Sammanfattning : Design of new materials with complex geometries is an important part of new innovative solutions for technical applications. With the use of additive manufacturing (AM), the design possibilities are endless and geometries that are impossible to manufacture by conventional techniques are available. LÄS MER

  5. 5. Qualification Aspects in Design for Additive Manufacturing : A Study in the Space Industry

    Författare :Christo Dordlofva; Anna Rönnbäck Öhrwall; Peter Törlind; Ola Isaksson; Carolyn Conner Seepersad; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Additive Manufacturing; Design for Additive Manufacturing; Qualification; Design for Qualification; Space Industry; Produktinnovation; Product Innovation;

    Sammanfattning : The aim of this research is to further the understanding of implications for product development and qualification when introducing additive manufacturing (AM) in the context of the space industry. Increased availability of AM machines and alluring potentials such as design freedom and cost-efficient product development and manufacturing has led to a rapid growth in the use of AM.
