Abstract (en)
[origin: WO2021074066A1] The invention relates to a method for producing a pressing tool (1, 51) provided for manufacturing a workpiece, which pressing tool has a pressing surface (2) having a structure consisting of elevations (4) and depressions (3). A mask (24) is applied in order to cover regions and then a metal layer (22) is applied to the regions (25) not covered by the mask (24) with the addition of mineral particles (23). This is repeated until the pressing surface (2) having the structure consisting of elevations (4) and depressions (3) is created by repeated, layer-by-layer application of masks (24) and metal layers (22) with the addition of mineral particles (23).
