三次元造形装置および三次元造形物の造形方法
Document Type and Number:
Japanese Patent JP7310214
Kind Code:
B2
Abstract:
A three-dimensional shaping device includes a supply flow channel through which a shaping material flows, an ejection amount control mechanism that controls a flow amount of the shaping material to be ejected from a nozzle, a branch flow channel branched from a first partial flow channel as a flow channel between the melting section and the ejection amount control mechanism out of the supply flow channel, a transfer mechanism that transfers the shaping material in the second partial flow channel to the first partial flow channel via the branch flow channel, and a control section that controls the transfer mechanism to transfer the shaping material in the second partial flow channel to the first partial flow channel in a period from stopping the ejection of the shaping material from the nozzle to resuming the ejection.
