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

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

   Abstract : Additive Manufacturing (AM) is on the verge of causing a downfall to conventional manufacturing with its huge potential in part manufacture. With an increase in demand for customized product, on-demand production and sustainable manufacturing, AM is gaining a great deal of attention from different industries in recent years. READ MORE

6. 4. Towards Design Automation for Additive Manufacturing : A Multidisciplinary Optimization approach

   Author : Anton Wiberg; Johan Andersson (Ölvander); Johan Persson; Lars Pejryd; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In recent decades, the development of computer-controlled manufacturing by adding materiallayer by layer, called Additive Manufacturing (AM), has developed at a rapid pace. The technologyadds possibilities to the manufacturing of geometries that are not possible, or at leastnot economically feasible, to manufacture by more conventional manufacturing methods. READ MORE

   Abstract : Additive Manufacturing (AM) for metals includes is a group of production methodst hat use a layer-by-layer approach to directly manufacture final parts. In recent years, the production rate and material quality of additive manufactured materials have improved rapidly which has gained increased interest from the industry to use AM not only for prototyping, but for serial production.
