The article focuses on laser deposition technology (LDT) and its application in laser cladding, repair and laser freeform manufacturing. LDT processes include direct metal deposition (DMD), laser metal deposition (LMP), laser additive manufacturing (LAM), and laser engineered net shaping (LENS). It uses a focused laser beam as a heat source for depositing metals. The author concludes that LDT is a maturing additive technology that provides new capabilities for creative repairs and cladding.
