Additive manufacturing in metal is a research field that interests me. How the AM process and geometries influence fatigue and damage tolerance needs to be understood to increase industry acceptance and to impose AM in high-performance products.

Additive manufacturing in metal

Additive manufacturing (AM) often called 3D-printing in metal is a relatively new production method that allows the manufacturer to automatically create physical components directly from a computer model.

AM can be used to produce industrial parts both lighter in weight, cheaper to produce, and with complex geometries that are difficult or impossible to produce with conventional methods.

The mechanical properties of metal AM-components can differ substantially from the properties of the same component produced by conventional techniques. This is due to the complexity of the AM-methods and the large quantity of process parameters. To gain industrial acceptance and to be able to introduce AM in high performance applications, a deeper understanding of how the AM process and geometries influence fatigue and damage tolerance properties, needs to be established.

In addition to my research at LiU, I’m research and implementation leader for AM at Saab Aeronautics.
