Abstract
Laser metal deposition process is an additive manufacturing technologies that utilize laser as its source of energy to fuse and melt materials together layer after layer to produce three dimensional solid part. Laser metal deposition process has gain a lot of popularities in the research community since its inception because of the exciting properties of the power source ‘laser’ and because of the great potential of the process. Laser delivers heat energy in a coherent manner and with low divergence thereby making the intensity of the laser beam to be very high and can be controlled as required thereby concentrating all the intensity at a point of interest. Laser metal deposition process the capability to produce novel product that maybe difficult if not impossible to fabricate using the conventional subtractive manufacturing processes. Laser metal deposition process can help to extend the service life of parts through the innovative repair process. A number of industries have benefited from these exciting technologies which include: aerospace, automobile, medicine and jewelry. This technology is fairly new and it is a promising technology that may change the way machines are produced. The focus of this chapter is to analyze the progress in this important additive manufacturing technology in term of research efforts in this area and the current state of these technology.
