Colton © GIT 2011 6 StereolithographyME 4210: Manufacturing Processes and Engineering Prof. J.S. Colton © GIT 2011 7 Stereo-lithography The computational steps in producing a stereolithography file. (a) Three-dimensional description of part. (b) The part is divided into slices (only one in 10 is shown). (c) Support material is planned. (d) A set of tool directions is determined to manufacture each slice. Shown is the extruder path at section A-A from (c), for a fused-deposition-modeling operation.ME 4210: Manufacturing Processes and Engineering Prof. J.S.
