ADDITIVE MANUFACTURING SYSTEM WITH ADDRESSABLE LASER ARRAY AND REAL-TIME FEEDBACK CONTROL FOR EACH SOURCE Russian patent published in 2023 - IPC B29C64/153 B29C64/268 B29C67/04 B22F3/10 B33Y10/00 B33Y30/00 B33Y50/02 

FIELD: array assemblies for combining laser beams.

SUBSTANCE: one embodiment is a system that includes a light source and is configured to provide a multi-spot 1-D image, a multi-spot 2-D image, or both on a powder pad. Moreover, the system contains a light source, which is in optical communication with an array of optical fibres for transmitting a multi-spot image. In addition, the optical fibre array is in optical communication with the imaging optics. At the same time, the image re-forming optics is configured to re-form a multi-spot image on the powder pad, and the light source provides power density for fusion and build-up of the part from the powder.

EFFECT: development of additive manufacturing systems that allow precise control of the print quality, in particular, parts that are built up will have lower porosity, lower defectiveness and better surface roughness.
