Summary: | The invention relates to a print head (100) for an additive fused deposition modelling method having a thermoplastic construction material, comprising:-at least one inlet (10) for receiving a construction material (11) into the print head;-at least one melt region, for melting the construction material (11), which is arranged downstream of the inlet (10) and is fluidically connected, at least temporarily, to the inlet (10); and-at least one first outlet (30) that is fluidically connected, at least temporarily, to the melt region (20), for discharging melted construction material (12) out of the melt region (29) at a first discharge rate; wherein-the print head (100) also comprises at least one second outlet (40) that is fluidically connected, at least temporarily, to the melt region (20) for discharging melted or non-melted construction material (11, 12) out of the melt region (20) at a second discharge rate; and-the first discharge rate can be influenced by a first discharge rate influencing device (50) for the melted construction material (12). |
