3D PRINTER FOR PRINTING ARTICLES CONSISTING OF MATERIALS WITH DIFFERENT ELECTROPHYSICAL PROPERTIES Russian patent published in 2019 - IPC B41J2/00 

FIELD: physics.

SUBSTANCE: invention relates to radio engineering, in particular to design of 3D printers based on the SLS method. Purpose of the invention is to expand the range of printed articles by using several types of particles of powdery material with different electrophysical properties for staged manufacture of the article in each printed layer consisting of different types of materials. Said technical result is achieved by the fact that it will be possible to use 3D printer for printing articles from materials of different electrophysical properties, characterized by that instead of one container containing particles of powdered material for sintering, with vertically movable bottom, adding several single-type containers containing particles of powder materials with different electrophysical properties, which in a given order will be used to form each printing layer, due to horizontal movement of movable platform with containers relative to working zone for sintering of article. Despite 3D printer design complication and the printing algorithm complication, using such a printing method will make it possible to create a wide range of not only radio electronic products, but also any multicomponent devices consisting of different materials.

EFFECT: technical result is to change design of 3D printer by adding additional containers capable of moving relative to the working area in a horizontal plane and containing particles of powdered material with different electrophysical properties, which will allow for stepwise sintering dissimilar materials when printing each layer.
