Research Status and Development Trend of Laser Additive Manufacturing Technology

Laser additive manufacturing (LAM) technology is one of the most representative of advanced manufacturing technology, and one of the most critical technology, is currently a hot research at home and abroad. This paper mainly introduces the forming principle, characteristics and research status of two typical LAM technologies--selective laser melting (SLM) technology and laser cladding deposition (LCD) technology. Moreover, some application examples of LAM technology are listed, and its future development trend is discussed.
