FORMATION METHOD OF SHAPED ARTICLE, AND THREE-DIMENSIONAL SHAPED ARTICLE MANUFACTURING APPARATUS

To provide a formation method of a three-dimensional shaped article with high shaping accuracy.SOLUTION: There is provided a formation method of a three-dimensional shaped article, comprising: a first ink application step as a step S1 for applying ink containing a polymerizable compound polymerized by irradiation of an ultraviolet ray, by being made into liquid droplets with an inkjet method, to a surface of a substrate whose surface is non-liquid-absorbable; a first solidification step as a step S2 for polymerizing/solidifying the polymerizable compound in a granular state at a first time interval; a second ink application step as a step S3 for applying the ink that is formed into the liquid droplets; and a second solidification step as a step S4 for polymerizing/solidifying the polymerizable compound at a second time interval. The second time interval is longer than the first time interval.SELECTED DRAWING: Figure 2 【課題】三次元造形物の高い造形精度の形成方法を提供する。【解決手段】三次元造形物の形成方法は、紫外線の照射により重合する重合性化合物を含むインクを、インクジェット法により液滴にして表面が非吸液性の基材の表面に付与するステップＳ１の第１インク付与工程と、第１の時間間隔を開けて重合性化合物を粒状のまま重合・固化させるステップＳ２の第１固化工程と、インクを液滴にして付与するステップＳ３の第２インク付与工程と第２の時間間隔を開けて重合性化合物を重合・固化させるステップＳ４の第２固化工程と、を有し、第２の時間間隔は第１の時間間隔よりも長い。【選択図】図２
