摘要: Abstract Additive manufacturing (AM) processes are increasingly being used to manufacture complex precision parts for the automotive, aerospace and medical industries. One of popular AM is selective laser sintering (SLS) process which manufactures by metallic, polymeric ceramic powder under effect power. The energy expenditure SLS its correlation geometry manufactured part parameters, however, have not received much attention from AM/SLS researchers. This paper presents a mathematical analysis required simple using process. total expended calculated as function area (TAS) convex hull based approach correlated geometry, slice thickness build orientation. TAS three sample results provided in paper. Finally, an optimization model presented computes minimal
