Heigh Energy Efficiency Optimization Method of Fused Deposition Modeling

To reduce the energy consumption in fused deposition modeling(FDM)and increase the utilization of energy,studied the optimization problem of efficient manufacturing parameters of FDM.Establish the energy efficiency target function of molten deposition manufacturing process with the optimal variable that nozzle temperature,formation height,air walking speed and printing speed,and with the optimization target that is maximum energy efficiency.Used the Taguchi method to design orthogonal experiment and obtain a process parameters with high energy efficiency.On this basis,established the energy efficiency optimization model by BP the network,and the adaptive niche genetic algorithm is used to solve the model.The research findings show that in order to achieve high efficiency in fused deposition modeling,the lower air speed and printing speed should be adopted under the circumstances that higher nozzle temperature and molding height.
