Abstract

Microwave assisted post-treatment of selective laser sintered green metal parts proved to be a new, fast and efficient way to densify complex-shaped elements, suitable for near-net-shape and net-shape manufacturing. Electromagnetic field modelling on pressed samples of RapidSteel 2.0 helped in choosing the proper experimental set up, using either single mode or overmoded microwave applicators operating at 2.45 GHz ISM frequency. LaserForm SLS green parts were exposed to high intensity microwave fields, using different lining configurations. Samples were characterized in terms of densification behaviour and microstructure: SEM observation of fracture and lapped surfaces allowed to analyse failure mechanisms and sintering degree.
