Research on optimization method of additive manufacturing process parameters based on energy saving

增材制造技术因其能够一层层打印出复杂的零件而日益备受关注,然而,增材制造技术的工艺参数繁多且相互影响,因此,合理选择工艺参数一直以来是研究的重点。为了解决这一问题,文中提出了基于节能的增材制造工艺参数优化方法。首先,分别建立了常见的增材制造技术,如熔融沉积成形(fused deposition modeling,FDM)、光固化立体成形(stereo lithography apparatus,SLA)和激光选区熔化(selective laser melting,SLM)的能源消耗、表面质量与工艺参数的关系。然后,提出了基于能源消耗和表面质量的多目标工艺参数优化模型。最后,利用FDM设备进行实验验证,实验结果表明:该优化方法是有效的。该方法能够为设计者在选择合理的工艺参数时,提供方法借鉴。

Additive manufacturing technology has attracted increasing attention because of its ability to print complex parts layer by layer.However,the process parameters of additive manufacturing technology are various and have mutual influence,so the reasonable selection of process parameters has been the focus of research.In order to solve this problem,an energy-saving-based additive manufacturing process parameter optimization method was proposed.Firstly,the energy consumption and surface quality of common additive manufacturing technologies such as fused deposition modeling(FDM),stereo lithography apparatus(SLA)and selective laser melting(SLM)were established respectively.Then a multi-objective optimization model of process parameters based on energy consumption and surface quality was proposed.Finally,FDM equipment was used for experimental verification,and the experimental results showed that the optimization method was effective.This method can provide a reference for designers when choosing reasonable process parameters.
