Abstract: The machine presents a working zone that is defined in an upper part of a build sleeve which is fixedly mounted in a chassis. Within the working zone, the object is supported by a build plate which slides inside the build sleeve when driven in vertical translation by the head of an actuating cylinder which is placed along a central axis of the sleeve. The build plate is positioned inside a transport container which is arranged removably between the sleeve and the actuating cylinder. The machine also includes a means for moving the transport container vertically into contact with the build sleeve. The container is open at its top and at its bottom so that, when the actuating cylinder is actuated, the head thereof can transfer the plate between the transport container and the build sleeve which forms a build envelope around the plate.

Abstract: A method and system for die compensation and restoration uses high-velocity oxy-fuel (HVOF) thermal spray coating and plasma ion nitriding to compensate for a particular part (damaged part) of a press die that causes formation of fine curves at a door of a vehicle to restore it to its original state. A coating thickness quantification technique may precisely compensate for the damaged part of the die that causes formation of the fine curves at the door of the vehicle in a circular form using HVOF thermal spray coating. A surface of the die may be nitrided using plasma ion nitriding after HVOF thermal spray coating is performed, so as to harden the surface of the die so that wear resistance and fatigue resistance of the die can be greatly improved and the hardfacing or overlay welding efficiency of the die can be increased.
