Laser Transmission Technology of Laser Additive Manufacturing

Abstract

The laser additive manufacturing technology is a laser assisted direct metal manufacturing process. This process offers the ability to make a metal component directly from CAD drawings. The manufacturing equipment consists of some components. Among them, the laser transmission component plays an important role in the whole fabricating process. It provides the energy source to melt the metal powder, so it is necessary to develop the laser transmission technology. This technology is achieved primarily by laser generator system and optical path transmission system. The related structure design and function implementation prove that the laser transmission technology can generate desirable laser power at precise assigned position, and complete the manufacturing process with flying colors.
