To provide a three-dimensional printer with excellent durability and a method for shaping three-dimensional objects using the printer.SOLUTION: A three-dimensional printer is equipped with a hot end that heats, melts, and dispenses shaping material by means of a heating plate 15 having an insulating substrate 151 and a heating resistor layer 152 formed on the insulating substrate 151, and voltage application means that applies voltage to heat the heating plate 15. The voltage application means applies a polar alternating voltage to the heating resistor layer 152.SELECTED DRAWING: Figure 3 【課題】耐久性に優れた３次元プリンタ及びこれを用いた立体造形物の造形方法の提供。【解決手段】絶縁基板１５１及び絶縁基板１５１上に形成された発熱抵抗体層１５２を有する加熱板１５により造形材料を加熱し融解して吐出するホットエンドと、前記加熱板１５を発熱するために電圧を印加する電圧印加手段と、を備えた３次元プリンタであって、電圧印加手段は、発熱抵抗体層１５２に極性交番電圧を印加することを特徴とする。【選択図】図３
