Additive manufacturing is a manufacturing technology which in recent years has received a lot of attention. Additive manufacturing, a concept incorporating several different manufacturing techniques, allows for the manufacturing of components with complex design features, using both conventional and novel materials. As the industry begin to utilize these new manufacturing techniques there will inevitably be many complex questions regarding the microstructure, mechanical performance and tribological properties of additively manufactured components.

My role as a PhD student at Uppsala University is to study the process step, the resulting microstructure and the mechanical performance of materials produced using the Laser Powder Bed Fusing process. To achieve this, I have access to many analytical means e.g. SEM equipped with EDS/EBSD, TEM as well as synchrotron light sources. Furthermore, I asses additively manufactured materials for their tribological properties which are dictated by the microstructure in the surface of the material. The aim of my work is to be able to control the microstructure locally by the means of process control, and by doing so, improve tribological and mechanical properties.

My work is part of a SSF-project with participants from Uppsala University, Lund University, Malmö University and Luleå Tekniska Högskola. Within the project, which has a strong industrial focus, expertise in material analysis, material development and material modelling can be found as well as access to large scale research facilities.
