Master Thesis: Functionalized Metal-Graphene Filaments for 3D-printing

Are you interested in doing your master thesis on the latest advanced materials and manufacturing technology? Please consider this opportunity to be part of a dynamic and innovative environment!

Background

The rapid movement towards electrification and digitalization of our society places new demands on materials and manufacturing technologies. Currently available engineering materials face major challenges for meeting future industrial needs with requirements for decreased weight, higher speeds, higher stability and lower environmental footprints. Additive Manufacturing (AM), commonly labelled as 3D-printing, is a rapidly developing production technology. However, the numbers of materials available today in e.g. powder-based methods are rather limited. This means that there is a crucial need to explore new material combinations in additive manufacturing. Recently, there has been a great growing interest in graphene owing to its unique psychochemical and mechanical properties. It has been shown that the properties of metals/alloys can be remarkably enhanced by adding low concentration of graphene-based additives. The aim of this master thesis work would be to contribute with developing novel materials with extraordinary properties!

Project Description
