Abstract Details

2014, MS, University of Cincinnati, Engineering and Applied Science: Mechanical Engineering.
Additive Manufacturing (AM) is a process of manufacturing parts by combining layers of materials which are deposited on top of each other. AM processes have become very popular among different industries particularly in the automotive, medical and aerospace sectors due to the ability of the AM processes to manufacture complex parts rapidly without the need for specialized tooling. In the AM process, the CAD file is converted into a stereolithography (STL) file, which is the industry standard used as an input to AM processes. This STL file is then sliced by the AM machine into successive layers for depositing material. Since the STL file is a planar approximation of the CAD surface, the contours of the slices are also piecewise linear approximation of the CAD contour. This linear approximation leads to errors in the boundaries of the contours which lead to errors in the surfaces of the manufactured part.
