1. 1. Aspects of building geometry and powder characteristics in powder bed fusion

   Författare :Alexander Leicht; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; direct metal laser sintering; stainless steel; powder recycling; thin wall structures; 316L; microstructure; electron beam melting; powder bed fusion; additive manufacturing;

   Sammanfattning : Additive manufacturing (AM) produces near-net-shaped parts directly from a 3D-CAD model in a layer-by-layer manner. One of the most common AM technique for fabricating metallic components is powder bed fusion (PBF). The PBF process has shown great potential in fabricating metallic parts with properties better or comparable to conventional methods. LÄS MER

3. 2. Laser powder bed fusion of 316L stainless steel - Microstructure and mechanical properties as a function of process parameters, design and productivity

   Författare :Alexander Leicht; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensile properties; productivity; design for additive manufacturing; additive manufacturing; thin-wall structures; stainless steel; laser powder bed fusion; microstructure; 316L;

   Sammanfattning : One of the most common additive manufacturing techniques for fabricating metallic components is laser powder bed fusion, which has demonstrated great potential in fabricating parts with properties exceeding the properties achieved via conventional methods. To fully utilize the process’s potential, a more profound understanding of the microstructure and properties of the laser powder bed fusion processed material is required. LÄS MER
