An apparatus for converting sheet material into a three-dimensional object comprised of layers of the material is disclosed. One embodiment of the apparatus comprises a work station (44) adapted to receive the sheet material (41) and a bonding tool (76) mounted to move relative to the work station (44) to bond layers of sheet material (41) to each other to form the three-dimensional object. The bonding tool (76) heats at least a portion of the sheet material (41) to its cohesion melding temperature. The apparatus additionally comprises a material dispensing assembly (30) mounted to supply the sheet material (41) to the work station (44). The dispensing assembly (30) supplies a release sheet (43) adjacent to the sheet material (41) such that the release sheet (43) is interposed between the bonding tool (76) and the sheet material (41) during bonding to prevent heated sheet material (41) from adhering to the bonding tool (76). |
