The invention relates to the field of the additive manufacturing of components, which are formed by the direct deposition of a substance, in the form of granules of a metal or non-metal, which passes from a reservoir into a melt bath, produced by the thermal energy of a laser or electron beam, and subsequently crystallizes. The granules enter the melt bath without the intervention of a gas stream, the path and rate of travel of said granules changing while they are in flight under the effect of an electromagnetic field. The granules travel within a chamber, falling into the melt bath from above from a reservoir, from which they are fed at a set speed by the rotation of an adjustable screw feed, and passing through a system of electromagnetic devices, which control the path of the granules by means of electromagnetic fields. The coordinates of this path are tracked by sensors, which transmit a signal to a computer, wherein the flight path of the granules is adjusted by control via the electronic devices and the delivery speed and volume of the substance is adjusted by adjusting the rotation of the screw feed. The invention increases the efficiency of the production cycle, reduces the dimensions of the equipment and increases the accuracy and speed with which material is delivered for the manufacture of a component, while enabling adjustment of the amount, temperature, path and fraction of said material and increasing the strength of the component.
