Shaping Material Supply Device And Three-Dimensional Shaping Apparatus

A three-dimensional shaping apparatus comprising:

• a nozzle having a discharge port, that is configured to discharge a shaping material from the discharge port;
• and
• a flow rate regulation mechanism that includes a butterfly valve, a drive shaft, and a valve driver, the butterfly valve being provided in a flow path upstream of the discharge port, the valve driver being configured to rotate the drive shaft,
• wherein the butterfly valve is rotated by the rotation of the drive shaft,
• when the butterfly valve is at a first position, the butterfly valve prevents the shaping material from being discharged from the discharge port, and
• when the butterfly valve is at a second position different from the first position, the shaping material is discharged from the discharge port via the butterfly valve.
