Abstract: 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.

Abstract: Provided is a slicing 2D data-based pattern application method for generating an output code in which the inside of a model is filled with a pattern, so as to reduce a binder usage amount and maintain a strength and a shape in sand binder jetting additive manufacturing. A slicing 2D data-based pattern application method according to an embodiment of the present invention comprises the steps of: generating 2D data by slicing an output model; generating an inner pattern in at least one of layers forming an output model in consideration of the set thickness of the layers and the outer thickness thereof and generating an output code by applying the generated inner pattern. Therefore, the cost of producing an additive manufacturing output can be reduced by reducing the binder usage amount through the application of the inner pattern.
