Zusammenfassung:	PROBLEM TO BE SOLVED: To achieve low power consumption and long life and further improve the quality of a three-dimensional model produced by using UV-LED as a light source.SOLUTION: The three-dimensional printer includes: a print head 16 having a plurality of jet nozzles for jetting photo-curable resin; a UV-LED irradiation unit 14 having a plurality of UV-LED chips which irradiates ultraviolet light to the photo-curable resin jetted by the plurality of jet nozzles to cure the photo-curable resin; a controller 20 for making the jetting areas of a plurality of jet nozzles and the irradiating areas of a plurality of UV-LED chips substantially identical by driving and controlling the plurality of jet nozzles and the plurality of UV-LED chips interlockingly.SELECTED DRAWING: Figure 7 【課題】ＵＶ−ＬＥＤを光源として用いることで低消費電力、長寿命化を図るとともに、生成される三次元造形物の更なる高品質化を図る。【解決手段】三次元プリンタは、光硬化樹脂を噴射する複数の噴射ノズルを備えるプリントヘッド１６と、複数の噴射ノズルにより噴射された光硬化樹脂に紫外光を照射して硬化させる、複数のＵＶ−ＬＥＤチップを備えるＵＶ−ＬＥＤ照射ユニット１４と、複数の噴射ノズル及び複数のＵＶ−ＬＥＤチップを連動して駆動制御し、複数の噴射ノズルによる噴射エリアと複数のＵＶ−ＬＥＤチップによる照射エリアを実質的に同一とするコントローラ２０を備える。【選択図】図７
