FDM三维打印的支撑结构的设计算法

In this paper, we present a method for automatically generating support structures for fabricating 3D objects with fusion deposition modeling (FDM) printers. First, we search for the parts of the 3D object model that cannot be printed normally (called unprintable parts). Then, we add some necessary support structures to all those parts. These support structures connect those unprintable parts to the object itself, or to the bottom plane. In addition, the support structure is corrected to increase stability while printing the object. For models of different sizes, we can adjust the density and width of the support structures in order to ensure stability and reliability in the printing process. Compared with existing methods, our method can reduce material cost and computation time.
