摘要:
An apparatus for forming an integral three-dimensional object from a plurality of individual laminations includes a cutting surface on which each of the laminations is individually deposited. A concentrated energy source cuts each of the plurality of laminations into a shape required for assembly of the laminations into the integral three-dimensional object. A transfer mechanism removes each of the cut laminations from the cutting surface and stacks each of the cut laminations on an assembly surface. The transfer mechanism includes a gripper face having a peripheral portion and a central portion. A mask is positioned on the gripper face. The mask has an apertured central portion corresponding to the cut lamination. A source of suction communicates with the gripper face and a valve mechanism selectively draws a suction on the gripper face peripheral portion, the gripper face central portion, both or neither. An electronic control device is provided for controlling the operation of the cutting surface, the concentrated energy cutter and the transfer mechanism.
