A method for producing multilayer abrasive particles (12) is proposed, comprising the method steps of: providing a substrate support (01) and at least one dispersion of an abrasive particle precursor (05); repeated positioning of at least one grid structure (02) above the substrate support (01), wherein covering regions (03) are defined by at least partially covered grid meshes (11) and printing regions (04) are defined by open grid meshes (11); applying the at least one dispersion of an abrasive particle precursor (05) to the grid structure (02), wherein contact is created between the grid structure (02) and the substrate support (01) or layers (08) arranged on the substrate support (01), and wherein, when the contact is broken, a layer of dispersion (07) is deposited in the printing regions (04) on the substrate support (01) or on the layers (08) already arranged on it, and subsequent drying of the respectively deposited layer of dispersion (07) to form a layer (08). |
