In the present embodiment, semi-automatic or automated operation between the work platform 110, the spray device 120, and the host 140 is implemented, for example, using computer numerical control (CNC) machining techniques. More specifically, the host 140 is, for example, a computer host or a computer numerical control (CNC) machining system coupled to the work platform 110 and the injection device 120 to transmit control signals to the work platform 110 and the injection device 120, and to control the injection device 120. Moving relative to the work platform 110 in the XYZ three-dimensional axial direction.

The work platform 110 is adapted to carry a work piece 210, such as a part that is structurally defective or partially damaged. The spray device 120 is disposed above the work platform 110 and the spray device 120 includes a laser light source 122.

The workpiece processing apparatus 100 of the present embodiment processes the workpiece 210 by, for example, a metal lamination manufacturing technique in conjunction with a laser sintering technique. The feed unit 130 is coupled to the spray device 120 and is adapted to provide a build material 150. The building material 150 of the present embodiment is, for example, a mixture containing a metal powder and an adherend.
