To provide a three-dimensional modeling device capable of improving the modeling accuracy of three-dimensional modeling objects without reducing convenience, even when the modeling material contains a binder.SOLUTION: The three-dimensional modeling system is equipped with a stage, a discharge unit that discharges modeling material, a laser irradiation unit, a moving unit, and a control unit. The control unit performs molding control to mold a three-dimensional object by heating the molding material ejected onto the stage by the ejection unit, the molding control includes a first control for the laser irradiation unit when the laser is irradiated to the molding material included in the target area, and the first control is a control that changes either one or both of the two parameters other than the first parameter so that, when the first parameter of the three parameters of laser output, speed, and width is changed, the value obtained by dividing the output by the product of the speed and width is a value in the range of 80% to 120% or less with respect to the predetermined value.SELECTED DRAWING: Figure 1 【課題】造形材料にバインダーが含まれている場合において、利便性を低下させることなく、三次元造形物の造形精度を向上させることができる三次元造形装置を提供すること。【解決手段】ステージと、造形材料を吐出する吐出部と、レーザー照射部と、移動部と、制御部を備え、制御部は、吐出部によってステージ上に吐出された造形材料を加熱することによって三次元造形物を造形する造形制御を行い、造形制御は、対象領域に含まれる造形材料へレーザーを照射させる場合におけるレーザー照射部についての第１制御を含み、第１制御は、レーザーの出力、速度、幅の３つのパラメーターのうちの第１パラメーターを変化させる場合、当該速度と当該幅との積で当該出力を除した値が、所定値を基準として８０％以上１２０％以下の範囲内の値となるように、第１パラメーター以外の２つのパラメーターのいずれか一方又は両方を変化させる制御である、三次元造形装置。【選択図】図１
