Quick-detachable 3D printing forming platform and use method

A quick-detachable 3D printing forming platform comprises a base. A box body is fixedly installed on the base. A port is formed in the top of the box body. A heat conduction piece is fixedly installedon the inner wall of the port. A semiconductor chilling plate making contact with the heat conduction piece is fixedly installed on the top of the inner wall of the box body. The quick-detachable 3Dprinting forming platform has the advantages that the structure is simple, operation is easy, a uniform frozen layer is arranged on the platform through the semiconductor chilling plate, the frozen layer is ground to be flush with the platform, a product is printed on the top of the frozen layer during 3D printing, in this way, the bottom of a workpiece can be firmly attached to the platform, a rubber strip can be quickly formed and prevented from hot melting, after 3D printing is completed, electrodes of the semiconductor chilling plate are reversely connected, so that a cold end performs heating and a hot end perform
