The present invention relates to a three-dimensional printer capable of enabling circulation of a liquid resin. The three-dimensional printer comprises: a circulation pipe for forming a circulation channel through which a liquid resin is withdrawn from a resin tank and then resupplied to the resin tank; a circulation pump installed in the circulation channel to circulate the liquid resin; a heating unit installed in the circulation pipe to heat the liquid resin withdrawn from the resin tank; and a filter for filtering impurities in the liquid resin heated by the heating unit. According to the present invention, the three-dimensional printer is capable of removing hardened floating matter, which is partially hardened and floating in the liquid resin, so as to enhance the molding quality of a sculpture and increasing a reuse rate of the liquid resin. |
