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.
