APPLICATION HEAD IN ADDITIVE MANUFACTURING Russian patent published in 2018 - IPC B41J2/00 

FIELD: technological processes.

SUBSTANCE: application head in additive manufacturing may include a material feeding device, consisting of the first feeding device for applying the first parent material to the growth surface, of the second feeding device for applying the second parent material to the growth surface and an electromagnetic energy source for directing the electromagnetic energy to the growth surface. The electromagnetic energy is used to form a melt zone on the growth surface, and the melt zone can include at least one of such materials as a molten first parent material and a molten second parent material, while the first parent material and the second parent material have a different structure.

EFFECT: possibility of layer-by-layer manufacturing of both high-quality or miniature and large structural features without sacrificing the performance of the application and reducing the subsequent machining of a three-dimensional product.
