Title:
溶融材料供給装置、三次元造形装置
Document Type and Number:
Japanese Patent JP6969288
Kind Code:
B2
Abstract:
To provide a molten material supply device which controls start and stop of feeding of a molten material and an amount of the fed molten material.SOLUTION: A molten material supply device used for a three-dimensional shaping device includes: a first flow channel which flows a molten material formed by melting a thermoplastic resin; and a rotor having a second flow channel which can communicate with the first flow channel, a nozzle which communicates with the second flow channel, and a flow rate adjustment mechanism which is provided on the second flow channel and adjusts a flow rate of the second flow channel. When the rotor is at a first position, the molten material is fed from the nozzle in a state in which the first flow channel and the second flow channel communicate with each other, when the rotor is in a second position rotating from the first position by a predetermined angle or more, an opening of the nozzle is blocked with a member surrounding the rotor, and feeding of the molten material from the nozzle is stopped.SELECTED DRAWING: Figure 1
