Brushes are used in the printing industry as an integral part of printing machines. In industrial printing machines, brushes are integrated in order to clean the ink that accumulates on the cassette, assist in guiding the paper on the printing line, and discharge the large amounts of static electricity that accumulate in the printing process. In the new generation of 3D printers, brushes can be found that assist in a clean flow of printing material, and clean remnants and surpluses.
