Abstract: The three-dimensional printer head for printing metal articles, the printer comprises a nozzle that is cylindrical and manufactured from a heat-resistant material with low electric conductivity, an embedded channel within the nozzle and running along a longitudinal length of the nozzle; a receiving space at a first end of the embedded channel in which a solid metal material is received; an extrusion space at a second end of the embedded channel from which a continuous bead of liquid or semisolid metal material is extruded, a feeder mechanism that continuously drives the solid metal material into the embedded channel through the receiving space, an induction coil surrounding an outer surface of the nozzle and extending over a substantial portion of the longitudinal length of the nozzle.
