"The Laser Aided Manufacturing Processes (LAMP) developed at the University of Missouri--Rolla is used to fabricate three dimensional metal parts. The powdered metal material are melted using a laser onto a substrate. The CAD model is basically converted to a format called STL files where the model is split into numerous triangles. This facilitates the slicing of the CAD model. Toolpath generation software is used to generate the deposition toolpath from the STL file. The laser scans the substrate and deposits the part according to the slices and slowly finishes the part to near net shape. This thesis describes the optimization of the process parameters for the deposition of functionally graded copper and tool steel. Experiments were conducted to optimize the parameters such as, laser power, powder flow rate, outer gas, feed rate for different percentage of copper and steel. Four point bending test was carried out on the laser deposited samples to study the interfacial strength of the deposit. Microstructure of the tested samples is also discussed"--Abstract, page iv.
