METHOD AND APPARATUS FOR MANUFACTURING THREE-DIMENSIONALLY SHAPED ARTICLE

[Object] In a method for producing a three-dimensional object using nozzles, at least a partial recovery is realized from an adverse effect caused by an abnormal nozzle that is abnormal in the amount of ejection. [Means of Realizing the Object] Over a lower layer (L1a), an upper layer (L1b) is forme...

Zusammenfassung:	[Object] In a method for producing a three-dimensional object using nozzles, at least a partial recovery is realized from an adverse effect caused by an abnormal nozzle that is abnormal in the amount of ejection. [Means of Realizing the Object] Over a lower layer (L1a), an upper layer (L1b) is formed in such a manner that hitting positions of droplets ejected from nozzles (6) are different from hitting positions of droplets ejected in forming the lower layer. In forming the upper layer, a droplet ejected from a recovery nozzle (E) hits a hitting position of a droplet ejected from an abnormal nozzle (A) in forming the lower layer. The amount of ejection from the recovery nozzle (E) is adjusted based on the amount of ejection from the abnormal nozzle.
