THREE-DIMENSIONAL SHAPING APPARATUS, THREE-DIMENSIONAL SHAPING METHOD, AND INFORMATION PROCESSING DEVICE

摘要

A three-dimensional shaping apparatus includes a control unit configured to control a supply unit, a leveling unit, and an ejection unit to repeat a set of processes of supplying powder, forming powder layer, and ejecting shaping liquid to shape a three-dimensional shaped object corresponding to the shaping target. The control unit is configured to stop the set of processes in response to reception of a stop signal, and in response to reception of a resume signal after the reception of the stop signal, control the supply unit, the leveling unit, and the ejection unit to eject the shaping liquid onto at least a part of a dot region on a surface of an outermost powder layer, the dot region being formed by at least one dot formed at the outermost powder layer, and then resume the set of processes.

1. A three-dimensional shaping apparatus comprising:
a supply unit configured to supply powder; a leveling unit configured to level a surface of the supplied powder in a first direction to form a powder layer; an ejection unit configured to eject shaping liquid to at least one position on a surface of the powder layer, the at least one position corresponding to a shaping target, to form at least one dot; a control unit configured to control the supply unit, the leveling unit, and the ejection unit to repeat a set of processes of supplying the powder, forming the powder layer, and ejecting the shaping liquid to shape a three-dimensional shaped object corresponding to the shaping target; and a reception unit configured to receive a stop signal indicating a stop of operation and a resume signal indicating resuming of the operation, the control unit being configured to stop the set of processes in response to reception of the stop signal, and in response to reception of the resume signal after the reception of the stop signal, control the supply unit, the leveling unit, and the ejection unit to eject the shaping liquid onto at least a part of a dot region on a surface of an outermost powder layer, the dot region being formed by at least one dot formed at the outermost powder layer, and then resume the set of processes.
