The invention relates to a printer head (1) for 3D printing of glass, the printer head comprising a heating body (8) made of a refractory metal, a through hole (20) arranged in a central part of the heating body for feeding glass through the heating body (8), a nozzle (5) arranged on the heating body (8) at an outlet of the through hole (20), and an induction coil arranged around the heating body and to heat the heating body by way of electromagnetic induction if a HF voltage is applied across the induction coil. By feeding glass filaments through the through hole of the heating body which is heated by the induction coil, the filaments will melt and will leave the printer head in melted form as a glass ribbon. The glass ribbon will solidify soon after it is printed onto a printer table or an already printed layer placed on the printer table. |
