In this paper, the research on part building orien ta tion optimization in RP&M is performed. Quality and efficiency related to the pa rt fabrication orientation in SL(stereolithography) process are discussed. In co nsideration of the cantilever deformation, stair-stepping effect, overcure and building time, the rules for part building orientation optimization is defined.O rientation optimization of the objective function & derivation method using G A( genetic algorithm) are also given. Employing Sun J2EE, the ASP tool of part buil ding orientation optimization is developed, which has been successfully applied to the networked and integrated RP&M service system.
