Abstract:
A three-dimensional printing device includes a receiver structured to receive a curing liquid ejected from nozzles at a receiving surface, and a detector detecting a position, on the receiving surface, of the curing liquid. A controller controls an ejection head such that inspection ejection of ejecting the curing liquid toward the receiver is performed at least before and after a three-dimensional object is printed, and causes the detector to detect a position, on the receiving surface, of the curing liquid in the inspection ejection. The controller determines whether or not each of the plurality of nozzles has an ejection abnormality, based on the position, on the receiving surface, of the curing liquid.

Claim (Index 1):
A three-dimensional printing device, comprising:\n a printing table on which a powder material is placeable; an ejection head including a nozzle surface that includes a plurality of nozzles from which a curing liquid curing the powder material is ejected; a transporter that moves the ejection head, with respect to the printing table, to at least a first position above the printing table and a second position; a receiver including a receiving surface that faces the nozzle surface in a state where the ejection head is at the second position, the receiver being structured to receive the curing liquid ejected from the plurality of nozzles at the receiving surface; a detector that detects a position, on the receiving surface, of the curing liquid ejected toward the receiver from the plurality of nozzles; and a controller configured or programmed to include:\n a printing controller that controls the ejection head such that the curing liquid is ejected toward the powder material on the printing table to print a three-dimensional object; \n an inspection ejector that controls the ejection head and the transporter such that inspection ejection of ejecting the curing liquid toward the receiver is performed at least before and after the three-dimensional object is printed; \n a detection controller that controls the detector such that the position, on the receiving surface, of the curing liquid in the inspection ejection is detected; and \n a determiner that determines whether or not each of the plurality of nozzles has an ejection abnormality, based on the position, on the receiving surface, of the curing liquid in the inspection ejection.
