Developing new wire DED processes with the Multiple Energy Source (MES) approach

This research area aims to develop new DED processes for high deposition rate, net shape wire additive manufacture. The main concept is based on independent control of the volume of deposited material and dimensions of deposited beads, which is achieved by dynamically varying the energy profile of the heat source through independent control of the energy density of different power sources. This allows to break natural aspect ratio of the liquid metal and build at higher rates whilst maintaining high accuracy.  The main goal is to detach from standard processes established for welding and develop new processes optimised for additive manufacture, considering also the thermal requirements of advanced materials used in additive manufacture.
