Mechanical testing and characterization of metallic 3D-printed specimens

Background
Metal 3D-printing (additive manufacturing) is an emerging, highly attractive technology in both research and industry sectors. This state-of-the-art manufacturing process can compete with traditional manufacturing for instance in light-weight porous structures as well as in prototyping. On the other hand, metal 3D-printing is a complex and not completely explored technology. Therefore a significant amount of research is required in order to overcome the challenges of 3D-printing and improve the properties of the printed components. Innovation Fund Denmark has made a large investment in the AM-LINE project that involves DTU, the Danish Technological Institute and several Danish companies. The main objective of DTU -in the frame of this project- is to establish a connection between the manufacturing process, the material microstructure and the mechanical properties of the printed part. The project also involves PhD students, therefore close collaboration and supervision are expected from them.

Scope of the work
The project will mainly focus on mechanical testing and evaluation of already designed and printed specimens. The intended experiments include tensile testing, fatigue crack growth testing, and testing of whole components like a hip implant stem. Different materials such as stainless steel and titanium, as well as specimen geometries will be considered. For instance, both solid and lattice structured coupons will be investigated. Depending on the student's interests and background, the project can additional encompass material characterization of test specimens or finite element modeling of the experiments.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
