Optimum Design for RP Deposition Orientation by Genetic Algorithm

Rapid Prototyping(RP) technology is very flexible and agile in advanced manufacturing,and has a wide application range.The choice of the deposition orientation in rapid prototyping has an important influence on the accuracy of the model,the building time and the prototype cost.The slicing algorithms in common use can not satisfy the above mentioned requirements.In order to simultaneously obtain optimization of three objectives,a new algorithm is proposed for the multi-objective optimization by combining the uniform design and orthogonal design with the genetic algorithm.The new algorithm can find the optimal solution with less computation.Experimental results indicate that the improved algorithm is feasible than current algorithms in iteration times and computation time.
