    Författare :Cheng-Han Yu; Johan Moverare; Ru Lin Peng; Joe Kelleher; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot tensile testing; slow strain rate tensile testing; creep; anisotropy; crystallographic texture evolution; deformation twinning; Varmdragprov; Dragprov med låg töjningshastighet; kryp; anisotropi; kristallografisk textur; deformationstvillingar;

    Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a concept and method of a manufacturing process that builds a three-dimensional object layer-by-layer. Opposite to the conventional subtractive manufacturing, it conquers various limitations on component design freedom and raises interest in various fields, including aerospace, automotive and medical applications.
