Abstract
A laminated object manufacturing (LOM) system for forming a plurality of laminations into a stack to create a three-dimensional object. The system includes an X-Y plotter device positioned above a work table, the work table being vertically movable. The X-Y plotter device includes a forming tool for forming a layer from a sheet of material positioned on the work table. The layers are bonded to each other with heat sensitive adhesives provided on one side thereof. A bonding tool or fuser is mounted to translate across the work table and apply a lamination force and heat to each of the layers. The X-Y plotter device and bonding tool are mounted to translate along rails mounted on a common reference frame. The reference frame includes two rigid beams positioned on a base frame. A sensor is provided between the bonding tool and the reference frame to sense the force applied by the bonding tool to the laminations and adjust the height of the work table in response thereto. An infrared sensor senses the temperature of the layers to also provide feedback to a control device for adjusting the speed of the bonding tool. The forming tool may be a laser system which includes a laser mounted to the reference frame, a plurality of mirrors, and a lens mounted on the X-Y plotter device.
