Claims7
A three-dimensional shaping apparatus comprising:
- a first flow path through which a shaping material flows;
- a nozzle that is configured to communicate with the first flow path and discharge the shaping material;
- and
- a flow rate regulation mechanism that includes a butterfly valve, a drive shaft, and a valve driver, the butterfly valve being provided in the first flow path, the valve driver being configured to rotate the drive shaft,
- wherein the butterfly valve is a part of the drive shaft,
- when the butterfly valve is at a first position, the butterfly valve prevents the shaping material from flowing through the first flow path, and
- when the butterfly valve is at a second positon different from the first position, the shaping material flows through the first flow path via the butterfly valve.
