LASER PRINTING SYSTEM Russian patent published in 2018 - IPC B41J2/45 

FIELD: printing equipment; typewriters.

SUBSTANCE: invention describes a laser printing system for illuminating an object moving relative to a laser module of the laser printing system in a working plane, the laser module comprising at least two laser arrays of semiconductor lasers and at least one optical element, wherein the optical element is adapted to image laser light emitted by the laser arrays, such that laser light of semiconductor lasers of one laser array is imaged to one pixel in the working plane of the laser printing system, and wherein the laser printing system is a 3D printing system for additive manufacturing, and wherein two, three, four or a multitude of laser modules are provided, which are arranged in columns perpendicular to a direction of movement of the object in the working plane, and wherein the columns are staggered with respect to each other such that a first laser module of a first column of laser modules is adapted to illuminate a first area of the object, and a second laser module of a second column of laser modules is adapted to illuminate a second area of the object, wherein the first area is adjacent to the second area such that continuous illumination of the object is enabled.

EFFECT: object of the present invention to provide an improved laser printing system and a corresponding method of laser printing.
