Patent ID: 7600547

Claim:
A variable lamination rapid prototyping apparatus, comprising: a conveyor belt to longitudinally reciprocate a sheet; a support plate provided under the conveyor belt; a movable plate coupled to the upper surface of the support plate and movable in a transverse direction of the sheet; a pair of yokes rotatably coupled to respective opposite sides of the movable plate such that rotating shafts of the yokes are parallel with the transverse direction of the sheet; a first motor coupled to at least one yoke to rotate the yokes; a pair of rotating links rotatably coupled to the respective yokes; a pair of horizontal links arranged above and below the sheet to be parallel to each other and linked to opposite ends of the rotating links; a second motor coupled to at least one rotating link, thus translating the horizontal links; a hot wire connecting the horizontal links to each other such that cutting the sheet; a support table subsequently stacking a plurality of sheets cut by the cutting means, thus forming a 3-dimensional object; and a computer previously storing data about the 3-dimensional object therein and controlling the conveyor belt, the movable plate, the yokes, the first motor, the rotating links, the horizontal links, the second motor, the hot wire and support table based on the data.
