        Additive layer manufacturing (LM) is commonly used for manufacturing prototypes, tools and functional end products in a wide range of industries including medicine, automotive and aerospace industries. One of the key advantages of RM over conventional machining is the elimination of molds, dies, and other forms of tooling, and the consequent eradication of tooling restrictions. Moreover, almost infinite geometrical complexity, mass customization, individualization and material flexibility give RM other superior properties. For LM to prosper, the limitations of existing additive processes must be overcome, e.g. limitations such as repeatability, reliability, surface finish, material properties and productivity. At the University of Leuven, selective laser melting/sintering (SLM/SLS) of metals, ceramics and polymers is studied aiming to develop the process to a level enabling rapid manufacturing of complex and customized parts in a competitive way. In order to achieve this goal, various studies have been conducted. One of the studies focuses on the combination of Selective Laser Melting (SLM) and Selective Laser Erosion (SLE), which is a layer subtractive manufacturing technique, in order to improve surface quality and density as well as to modify the microstructure and mechanical properties. In the presentation, Selective Laser Melting will be explored with its main application areas and the hybrid process of SLM and SLE. Besides, the application areas of SLE, such as laser marking and 3D laser ablation will be presented.


Short Biography:


Evren Yasa obtained her Bachelor degree at Istanbul Technical University ( Istanbul, Turkey) in 2002 and her master of applied sciences (M.A.Sc.) degree at the University of British Columbia ( Vancouver, Canada) in the Department of Mechanical Engineering in 2004. She worked on machine tool metrology to measure and compensate for the volumetric errors of 3-axis machine tools. Afterwards, she worked as a research engineer at Sabanci University mainly focusing on conventional machining techniques and reverse engineering. She is currently working as a doctorate student at the Catholic University of Leuven in Belgium. She is a part of the research group on production processes in the Department of Mechanical Engineering. Her research activities mainly focus on Rapid Manufacturing processes, including Selective Laser Melting/ Erosion.
