Abstract: A three-dimensional forming system includes a three-dimensional forming apparatus and a control device. The three-dimensional forming apparatus includes a nozzle that discharges a forming material, an opening/closing mechanism that opens or closes a flow path connected to the nozzle, a moving mechanism that changes a relative position between the forming table and the nozzle, and a control unit that perform a control based on forming data. The control device includes a forming data generating unit that analyzes path data including a path indicating a movement direction and a movement distance of the nozzle and a discharge parameter indicating discharging of the forming material, generates the forming data by adding an opening/closing command for driving the opening/closing mechanism to the path data, and transmits the forming data to the three-dimensional forming apparatus.

Abstract: A manufacturing method of a three-dimensional formed object includes a first step of causing a forming material to be deposited on a forming table to form a first formed part including a recessed portion which is open in a direction heading from the forming table toward a nozzle through a discharging process of supplying a material to a flat screw to generate the forming material in which the material is melted and discharging the forming material from the nozzle toward the forming table, and a second step including a step of causing the forming material to be deposited inside the recessed portion through the discharging process and forming a second formed part which is fixed to an inside of the recessed portion in a shorter forming time per unit volume than a forming time per unit volume of the first formed part.

Abstract: In a manufacturing method of a three-dimensional formed object, the method includes a first discharging in which a forming material is continuously discharged from a nozzle while causing a position of the nozzle to change with respect to the forming table in a first direction which is perpendicular to a top surface of the forming table to cause the forming material to be deposited in the first direction, a second discharging in which the forming material is continuously discharged from the nozzle while changing the position of the nozzle with respect to the forming table in a second direction which is parallel to the top surface of the forming table to dispose the forming material along the second direction, and repeating in which the first discharging and the second discharging are repeated.
