THREE-DIMENSIONAL MOLDING DEVICE AND PLASTICIZING MATERIAL DISCHARGING DEVICE

Japanese Patent JP2023048382

A

To provide a three-dimensional molding device capable of accurately changing a discharge quantity.SOLUTION: A three-dimensional molding device comprises a plasticizing section, a nozzle for discharging a plasticizing material from a nozzle opening toward a stage, a discharge quantity adjustment section which is provided in a flow path through which the plasticizing material flows and is connected to the nozzle opening to adjust the discharge quantity of the plasticizing material from the nozzle opening by changing the area of the opening formed in the flow path, a pressure adjustment section which adjusts the pressure in the flow path through a branch flow path connected to the flow path between the discharge quantity adjustment section and the nozzle opening, and a control section which controls the discharge quantity adjustment section and the pressure adjustment section. When the discharge quantity is changed from a first discharge quantity to a second discharge quantity, the control section controls the pressure adjustment section to adjust the pressure in the flow path after changing the area of the opening by controlling the discharge quantity adjustment section. The second discharge quantity is a discharge quantity when the plasticizing material is being discharged from the nozzle opening.SELECTED DRAWING: Figure 1
