About me

Didunoluwa is researching the Additive Manufacturing (AM) process Laser Powder Bed Fusion (LPBF), a process that uses a laser beam to melt metal powder to form intricate parts for space applications. The LPBF technique has limitations. For example, the higher the build angle of a structure being printed in relation to the plate it is built on, the higher the superfluous effect of the laser beam with the metal powder. This results in partially melted powder to form on the part, causing a rougher surface and with that potential areas for cracks and stresses.  To reduce such surface roughness, support structures can be used. Hence, post processing is needed to remove surface roughness and the added supports. However, building support structures require extra material, and additional post processing is time consuming.

This is where Didunoluwa's research project will be put to use. His aim is to look at how engineering design methods can help solve AM problems such as surface roughness, thus enhancing the performance and reducing time to market for aerospace components.

In his project he will interview engineers in the aerospace industry to get a better understanding of the requirements needed to develop an effective design method for 3D-printed aerospace components. Furthermore he will use the equipment at Luleå University of Technology to make and evaluate small test prototypes. The aim is to provide engineers with a validated framework for AM design. It is a continuation of research conducted by Christo Dordlofva, PhD at Luleå University of Technology. Christo Dordlofva will also be involved in the current project.
