金属增材制造技术发展趋势综述

Summary of development trend of metal additive manufacturing technology

近年来金属增材制造技术的快速发展,使其在航空航天、医疗行业、汽车制造等领域得到了大量应用。本文简要介绍了金属增材制造的典型工艺、金属粉末和金属丝材的制备方法以及基于文献统计的方法分析金属增材制造目前的研究热点和发展趋势。结果表明,金属增材制造技术在仿真设计、制造工艺、过程监控、质量评估、后续处理等领域还没有形成完善的研究体系和标准规范,阻碍了不同增材制造技术的应用融合。研究的深入以及材料和工艺的扩展会促进金属增材制造技术的不断突破以更好的满足现代生产的需求,工艺数据库也会应运而生,对零件的性能控制更细化更完善。

In recent years,with the rapid development of metal additive manufacturing,it has been widely applied in aerospace,medical industry,automobile manufacturing,and other fields.In this paper,the typical processes of metal additive manufacturing,preparation of metal powder and metal wire are introduced,and the research hotspots and development trend of mental additive manufacturing are analyzed based on literature statistics.Results show that concerning the application of metal additive manufacturing technology,it has not formed a complete and standard research system in simulation design,manufacturing process,process monitoring,quality assessment,and post processing,which hinders the integration of different additive manufacturing technologies.With further research and expansion of materials and processes,more breakthroughs in metal additive manufacturing will be made continuously to better meet the needs of modern production.The process database will emerge in response to the proper time,and the control of part performance will be more refined and accurate.
