MODULAR SYSTEM FOR 3D PRINTING OF LAYERED COMPOSITE METALS FOR CNC MACHINES WITH FUNCTION OF QUICK CHANGE AND NON-ADJUSTMENT OF DEPOSITED MATERIAL Russian patent published in 2023 - IPC B23K9/04 B23K37/06 

FIELD: 3D printing.

SUBSTANCE: used to manufacture a product by three-dimensional printing by electric arc surfacing on CNC equipment that uses various wires in the production process. The cabinet is mounted on a movable support; in its upper rotating part there is a system for automatically feeding one of three welding wires into extruder. The fixed lower part houses a welding machine and spools of welding wire of different compositions. The feed mechanisms for each wire ensure that the welding wire is pulled from the spool through a fitting that has three input channels for different types of wires and one output channel for the specific wire being deposited. A guillotine, consisting of a pair of blades, ensures that part of the wire is cut off so that it can pass back through the channel. The extruder is configured to interact with a CNC milling machine to carry out surfacing.

EFFECT: modular 3D printing system ensures the production of layered composite products from combinations of various metals using 3D printing by electric arc surfacing using CNC equipment.
