Product modeling for additive manufacturing

The intrinsic limitations of traditional CAD modeling severely restrain the design space of additive manufacturing (AM). In order to maximize the technological superiority of AM, great effort should be made to optimize product performance and save manufacturing cost through considering the shape, size, hierarchical structure, and material composition in the design phase. According to AM characteristics, this paper summarizes the state-of-the-art research of AM product modeling in the following four aspects: complex shape modeling, complex material modeling, complex hierarchy modeling, and modeling for manufacturing. Based on this, future development trends in this field are discussed. Integrated modeling and lightweight modeling are considered as the potential development direction of AM product modeling.
