Design Considerations for a Directed Energy Deposition Cell
Hassel, Trond Arne; Brøtan, Vegard; Sørby, Knut (Chapter, 2023)Setting up a robotised additive manufacturing machine requires attention to several safety aspects, including integration of different systems, a functional work area, human-machine interfaces and convenience in operation. ... -
Determination of Anisotropic Mechanical Properties for Materials Processed by Laser Powder Bed Fusion
Hovig, Even Wilberg; S. Azar, Amin; Grytten, Frode; Sørby, Knut; Andreassen, Erik (Peer reviewed; Journal article, 2019)Improving the success rate in additive manufacturing and designing highly optimized structures require proper understanding of material behaviour. This study proposes a novel experimental method by which anisotropic ... -
High cycle fatigue life estimation of AlSi10Mg processed by laser powder bed fusion
Hovig, Even Wilberg; S. Azar, Amin; Sunding, Martin Fleissner; Sørby, Knut; M'hamdi, Mohammed; Andreassen, Erik (Journal article, 2018)Fatigue life is known to be dependent on the surface properties of the material. Surface roughness provokes local stress concentration and cause crack initiation even at minute cyclic loads. In laser powder bed fusion, ... -
An investigation of the anisotropic properties of heat-treated maraging steel grade 300 processed by laser powder bed fusion
Hovig, Even Wilberg; S. Azar, Amin; Solberg, Klas; Sørby, Knut (Peer reviewed; Journal article, 2021)In order to explore the possibilities enabled by laser beam powder bed fusion of metals (PBF-LB/M), reliable material models are necessary to optimize designs with respect to weight and stiffness. Due to the unique processing ... -
Mechanical Properties of AlSi10Mg Processed by Laser Powder Bed Fusion at Elevated Temperature
Hovig, Even Wilberg; S. Azar, Amin; M'hamdi, Mohammed; Sørby, Knut (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2020)AlSi10Mg processed by laser powder bed fusion is expected to have remarkable mechanical properties due to the dominant cellular microstructure. However, the as-processed material is often both anisotropic and containing ...
