PRINTING HEAD ASSEMBLY
First Claim
1. A printing head assembly, adapted to drive at least two filaments to form on a base layer-by-layer to construct a three-dimensional object, the printing head assembly comprising:
- a fixing member, having an inlet side and an outlet side opposite to each other;
at least two nozzle heads, respectively disposed at the outlet side of the fixing member, and each of the nozzle heads having a filament connection tube and a material extrusion port respectively penetrating through the fixing member, wherein the filament connection tube has a position-limiting portion;
at least two driving units, respectively disposed at the inlet side of the fixing member, and respectively driving the corresponding filament to feed into the material extrusion port of the corresponding nozzle head from the corresponding filament connection tube through the fixing member;
at least two position-limiting members, respectively disposed between the corresponding driving unit and the fixing member, and connected to the corresponding filament connection tubes; and
at least two position-restoring members, respectively disposed between the corresponding position-limiting member and the fixing member, and located on the corresponding filament connection tube, wherein each of the filament connection tubes respectively leans against the fixing member through the corresponding position-limiting portion or the corresponding position-limiting member, so as to limit the material extrusion port of each of the nozzle heads to move between a first height level and a second height level through the corresponding driving unit and the corresponding position-restoring member.

Abstract
A printing head assembly including a fixing member, two nozzle heads, two driving units, two position-limiting members, and two position-restoring members is provided. Each nozzle head has a filament connection tube and a material extrusion port respectively penetrating through the fixing member, wherein the filament connection tube has a position-limiting portion. The driving units drive the corresponding filaments to feed into the corresponding nozzle heads. The position-limiting members are respectively disposed between the corresponding driving unit and the fixing member, and are connected to the corresponding filament connection tubes. The position-restoring members are respectively disposed between the corresponding position-limiting member and the fixing member. Each of the filament connection tubes respectively leans against the fixing member through the corresponding position-limiting portion or the corresponding position-limiting member, so as to limit the material extrusion port of each nozzle head to move between a first height level and a second height level.
