Zusammenfassung:To shorten a molding time while suppressing deterioration of molding accuracy of a three-dimensional molding.SOLUTION: A three-dimensional molding apparatus 1 comprises: a nozzle 10 having a flow path 10b through which the molding material flows and a discharge port 10a discharging the molding material toward a table 14 by communicating with the flow path 10b; a position changing mechanism 26 for changing the relative position between the nozzle 10 and the table 14; a pressure measuring part 11 for measuring the pressure of a travel route of the molding material; a cleaning mechanism 24 cleaning the discharge port 10a; and a control part 23 that controls the nozzle 10 and the position changing mechanism 26 to laminate a layer of the molding material on the table 14 to mold a three-dimensional molding, in which the control part 23 interrupts, when the pressure measured by the pressure measurement part 11 in the middle of the molding process is a first reference value or larger, the molding process to make the cleaning mechanism 24 clean the nozzle 10.SELECTED DRAWING: Figure 1 【課題】三次元造形物の造形精度の低下を抑制しつつ造形時間を短縮する。【解決手段】造形材料が流れる流路10bと、流路10bと連通し造形材料をテーブル14に向けて吐出する吐出口10aと、を有するノズル10と、ノズル10とテーブル14との相対的な位置を変更する位置変更機構26と、造形材料の移動経路の圧力を測定する圧力測定部11と、吐出口10aをクリーニングするクリーニング機構24と、ノズル10及び位置変更機構26を制御して、テーブル14に造形材料の層を積層して三次元造形物を造形する造形処理を実行する制御部23と、を備え、制御部23は、造形処理の実行中に圧力測定部11によって測定される圧力が第1基準値以上である場合、造形処理を中断してノズル10をクリーニング機構24にクリーニングさせるクリーニング処理を実行する三次元造形装置1。【選択図】図1
