PROBLEM TO BE SOLVED: To reduce the mixing of a model material and a support material to each other to enhance fabrication speed.SOLUTION: When an object layer 10 is formed, a curing unit 24A, a flattening roller 23A, a first head 21 for model material, a second head 22 for support material, a flattening roller 23B, and a curing unit 24B are subsequently arranged from the upper stream side toward the lower stream side in an X1 direction (forward path) on a carriage 20. In the forward scanning, a model material 201 is discharged from the first head 21 to a fabrication area, and is flattened by the flattening roller 23A. In the backward scanning, a support material 202 is discharged from the second head 22 to a support area, and is flattened by the flattening roller 23B.SELECTED DRAWING: Figure 5 【課題】モデル材とサポート材の混合を低減し、造形速度の向上を図る。【解決手段】造形層１０を形成するとき、キャリッジ２０上に、Ｘ１方向（往路）において、上流側から下流側に向かって、硬化ユニット２４Ａ、平坦化ローラ２３Ａ、モデル材用第１ヘッド２１、サポート材用第２ヘッド２２、平坦化ローラ２３Ｂ、硬化ユニット２４Ｂの順に配置し、往路走査で第１ヘッド２１からモデル材２０１を造形領域に吐出させて平坦化ローラ２３Ａで平坦化し、復路走査で第２ヘッド２２からサポート材２０２をサポート領域に吐出させて平坦化ローラ２３Ｂで平坦化する。【選択図】図５
