摘要

近年來積層製造(3D列印)技術不斷演進，在市場的應用端，可免去模具的高昂費用與製做時程，具備客製化少量低成本的優勢；設計開發者也可藉此縮短開發時程，透過3D列印試製成品，驗證設計概念，先進歐美國家紛紛將雷射金屬沉積(LMD)製造技術導入航太、汽機車零組件、3C殼件、複雜的工具本體與結構體的製造[1]，分析LMD製程發展近程，成品雖然可直接應用於功能零組件，但仍有製造效率與尺寸精度議題，需要透過加法加工與減法加工之多功能複合製程方法，以滿足應用與製造需求；國際大廠也提出LMD複合製程技術，以因應LMD技術製造上所面臨的許多問題與挑戰。本文將針對雷射金屬積層製造與加減法複合製程控制技術、製程優勢及其應用進行介紹。

In recent years, additive manufacturing (3D printing) technology continues to evolve, in the application of the market side, the mold can be free from the high cost and long production time, allowing small quantity production and design customization in low-cost; designers can also shorten development time through the 3D printed products to verify the design concept. Advanced countries in Europe and U.S. have applied laser metal deposition (LMD) manufacturing technology into aerospace, automotive components, 3C shell, manufacturing of complex tool bodies and structures [1]. The roadmap of LMD recent development suggests that, although the finished product can be directly applied to functional components, the manufacturing efficiency and dimensional accuracy issues remain. Additive processing and reducing processing of multifunctional composite manufacturing process are required to meet the application and manufacturing needs. International companies also proposed LMD hybrid process technology, in order to overcome many of the problems facing and challenges in the LMD manufacturing process. This paper will focus on laser metal manufacturing, hybrid process manufacturing control technology, process advantages and applications.
