Abstract: Apparatus for facilitating automated removal of a printed part from a 3D printer's print bed includes a print surface applied to the print bed, wherein the print surface has properties which change with temperature, affecting adhesion to the printed part. Cycling the temperature of the print bed enables adhesion of the part to the print bed during printing and release of the part from the print bed upon completion of the print. The print bed may be oriented vertically or at an incline to the horizontal to enable gravitational forces to pull the printed part away from the print bed upon completion of the print. Peltier devices or other cooling mechanisms may be provided to facilitate cooling of the print bed for release of the part. In certain embodiments, the print bed is configured to provide mechanical part removal to automatically dislodge the printed part from the print bed.
