ABSTRACT
In 3D printing, a solid CAD model is sliced into layers of predetermined thickness by a special slicing software that is proprietary for each 3D printing machine. These sliced sections define the overall shape and geometry of the part collectively when stacked on top of each other. This chapter focuses on those system elements that affect the shape of the part: the CAD file, the stereolithography (STL) file, problems and repairs of STL files, and other file formats, which could be used instead of STL file. It presents a case study describing a complete design and 3D printing process of a simple eye bracket part. This case study familiarizes the reader about the basics of 3D printing of simple parts. This experience can also help prove the efficiency and flexibility of a CAM process, which involves 3D printing. Thus, 3D printing is essentially a part of automated fabrication technology allowing to manufacture 3D parts from their numerical and digital design.
