First Claim
1. A three-dimensional printing nozzle structure, comprising:
- a heater, having a first through hole;
a nozzle, connected to the heater, wherein the nozzle has a second through hole, and the first through hole and the second through hole are aligned with each other;
a feed tube, passing through the first through hole, wherein the feed tube has a feed channel, the second through hole and the feed channel are aligned with each other, a filament moves along the feed channel to pass through the heater, the heater heats and melts the filament, and the filament that has been melted moves from the feed channel into the second through hole to be extruded; and
a baffle member, disposed inside the first through hole and located between the feed channel and the second through hole, wherein the baffle member is configured to adjust a degree of communication between the feed channel and the second through hole.
