COATINGS FOR TEXTURED 3D PRINTED SUBSTRATES Russian patent published in 2022 - IPC B29C64/379 B33Y40/20 

Abstract RU 2768834 C1

FIELD: 3D printing.

SUBSTANCE: invention relates to a coated product. The coated product includes a product with a surface containing a set of low-profile elements. At the same time, the set of low-profile elements has surface roughness from 10 mcm to 200 mcm. In this case, the surface also contains a set of topographic elements with an average height that is more than 4 times greater than the average height of low-profile elements, and a coating system covering the surface. At the same time, the coating system contains one or more coating layers. In this case, the coated surface has surface roughness of less than 10 mcm, and the coating system has an average thickness between low-profile elements of ±50% of the surface roughness of the set of low-profile elements.

EFFECT: visual hiding of low-profile surface elements and giving optical properties to high-profile surface elements.
