Abstract
The invention provides a multifunctional heating plate used at the bottom of a 3D printer. The heating plate comprises a metal support plate, an insulating plate, a metal ceramic heating plate, a high-temperature resisting heat conducting film and a high-temperature glass plate. According to the heating bottom plate of the 3D printer, the metal ceramic heating plate serves as a heating material, edge warping of a printed object can be effectively prevented, the printing quality is improved, and damage of the heating bottom plate when the 3D printer breaks down can be effectively avoided. A temperature sensor can accurately feed back the actual temperature of the heating bottom plate of the 3D printer to a control circuit of the 3D printer in time. Due to the insulating plate, heat losses can be effectively reduced, and the temperature of the heating bottom plate is more stable and uniform. Due to the high-temperature resisting heat conducting film, heat on the metal ceramic plate can be transmitted to the high-temperature glass plate more effectively and evenly. The adhesion force of the high-temperature glass plate to plastic materials is high, the trouble of replacing high-temperature double-sided adhesive tape is saved, and the printed object can be easily separated from the 3D printer.
