A 3-dimensional printing system for manufacturing a part is provided. The system includes a building platform having a deposited pattern of metal powder, a sand dispensing nozzle selectively supplying sand to the building platform, a binder dispensing nozzle selectively supplying binder material to the building platform, a robotic arm supporting one or more of the sand dispensing nozzle and the binder dispensing nozzle, the robotic arm moving the one or more of the sand dispensing nozzle and the binder dispensing nozzle, and a processor controlling the robotic arm to position the one or more of the sand dispensing nozzle and the binder dispensing nozzle relative to the deposited pattern of metal powder and control the sand dispensing nozzle and the binder dispensing nozzle to supply powdered sand and binder, respectively, based on a Computer Aided Drafting file associated with the part.
A 3-dimensional (3D) printing system for manufacturing a part, the system comprising:
A sand injection system for a 3-dimensional (3D) printer having a building platform having a selectively deposited pattern of metal powder, the sand injection system comprising:
The sand injection system of 11, wherein the sand dispensing nozzle and, the binder dispensing nozzle, are all located on the robotic arm with a focused heat source of the 3D printer.
