1. An extruder head assembly for an additive manufacturing machine, the extruder head assembly comprising:
a melt zone component operatively connected to a cold end component for receiving and heating a filament advanced by the cold end component; and
a nozzle operatively connected to the melt zone component, the nozzle being configured to receive the filament having been heated from the melt zone component,
the melt zone component comprising:
a heat source, and
an interior member in thermal communication with the heat source, the interior member defining therein:
a passage configured to heat unmelted material of the filament,
at least one melt channel, and
at least one aperture fluidly connecting the passage to the at least one melt channel, the at least one aperture being configured to direct melted filament material toward the at least one melt channel,
the passage and the at least one melt channel fluidly connecting downstream from the at least one aperture, the nozzle being configured to receive heated filament material from the passage and the at least one melt channel.
