The laser technology process is a pulsating practice in the field of engineering and in all paces of lifespan; since it can travel a longer distance and be focused on a very small bright spot that exceeds the illumination of the sun. This present study reports on the modeling and the prediction of the volume of laser-deposited composites using the central composite design (CCD). Four input factors were put into consideration, which is the laser power, the scanning speed, the powder flow rate and the gas flow rate. Titanium alloy (Ti6Al4V) and copper (Cu) powders were coaxially deposited to form the bulk of a single clad. The factors considered determine the energy density and the melt pool delivered into the substrate and as such, influence the volume of the deposited composite (VDC) that was employed in the response surface methodology (RSM) design. This has been used to predict the actual process parameters for the optimum process setting.
