Abstract (en)

[origin: WO2022199735A1] The invention relates to a method for discharging particulate building material in a 3D printer, in which method: the building material curtain (6) consisting of particulate building material (2) is optically monitored in a working step in which the particulate building material (2) is discharged in a region of the building material curtain (6) between the applicator (1) and the construction area (4); an image of the building material curtain (6) is generated and/or at least one dimension of the building material curtain (6) is determined; the image and/or the at least one dimension is compared with an associated reference image and/or a predefined reference value and, if the image deviates from the reference image and/or the dimension deviates from the associated reference value, at least one discharge parameter for discharging the particulate building material (2) is changed.
