Multicriteria decision analysis framework for part orientation analysis in additive manufacturing

Abstract Additive manufacturing (AM) or three-dimensional printing (3DP) refers to producing objects from digital information layer by layer. Despite recent advancements in AM, process planning AM has not received much attention compared subtractive manufacturing. One of the critical issues is deciding part orientation. In this research, integrative framework multicriteria decision making for orientation analysis investigated. Initially, quantitative data are assessed using envelopment (DEA) technique without preferences a maker. contrast, maker’s qualitatively analysed analytic hierarchy (AHP) technique. Then, proposed combining explicit as DEA, implicit preference AHP, and linear normalization (LN) used, which reflects both objective supporting 3DP Two particular technologies, namely Fused Deposition Modelling Selective Laser Sintering, used case study illustrate algorithm, further verified with experts improve AM.
