Abstract

The invention discloses a 3D waxwork printer. A wax block is placed inside a temperature-control iron resistance heating container; after the wax block is heated to be melted, the melted wax is conveyed through a metallic conduit into a metallic print head which is a reciprocating-type plunger pump; and fan water-cooled copper blocks fit on the periphery to cool the print head. A temperature sensor is contained in the copper block. If temperature is too high, the fan will be triggered to speed up so as to expedite heat dissipation. In the printing process, the print head is controlled by a computer; driven by a gear, the print head moves according to three-dimensional model data saved in the computer to draw two-dimensional layers layer by layer so as to finally pile up a three-dimensional waxwork. By accurately controlling temperature of input liquid wax and the print head to output semi-solid wax, wax in the form given by the computer reaches the highest degree of adhesion so as to finally print a smooth and complete three-dimensional waxwork body.
