..., and their removal during post-processing is tedious and expensive. Therefore, reducing sacrificial supports is economically advantageous. The purpose of this paper is the reduction of sacrificial supports through the automated generation of integrated support structures. Design/methodology/approach Sacrificial...

...Giampaolo Campana; Eckart Uhlmann; Mattia Mele; Luca Raffaelli; André Bergmann; Jaroslaw Kochan; Julian Polte Purpose Support structures used in laser powder bed fusion are often difficult to clean from unsintered powder at the end of the process. This issue can be significantly reduced through...

...Matthijs Langelaar Purpose The purpose of this paper is to communicate a method to perform simultaneous topology optimization of component and support structures considering typical metal additive manufacturing (AM) restrictions and post-print machining requirements. Design/methodology/approach...

...Yang Liu; Zuyu Li; Peng Wei; Shikui Chen Purpose The purpose of this paper is to explore the possibility of combining additive manufacturing (AM) with topology optimization to generate support structures for addressing the challenging overhang problem. The overhang problem is considered...

... such as SLM and DMLS, support structures are used for manufacturing parts having such features. The manufacturing of the support structures adds to the total energy consumption in metal powder-based AM process. Although the energy consumption in the selective laser sintering (SLS) process which does...
