Provided is a nozzle clogging defect compensating method for compensating for a nozzle clogging defect appearing in a binder jetting stack manufacturing means. The nozzle clogging defect compensating method according to an embodiment of the present invention comprises the steps of: determining a defect occurrence region when a clogging defect of a nozzle used in the binder jetting stack manufacturing means occurs; determining whether compensation for the detect occurrence region is possible; when the compensation is possible, generating defect information and reflecting the defect information in an output code; setting a defect compensation region on the basis of the defect information; determining a defect compensation type of the defect compensation region; and reflecting a result of the determining in the output code. Accordingly, a replacement time and a replacement cost of an output head where the nozzle clogging defect has occurred can be saved, thereby reducing the unit production cost of a binder jetting type stack manufacturing output.
