A nozzle of reinforcing material co-printing type 3d printer for construction

A nozzle of a reinforcement material co-printing type 3D printer for construction, wherein in a nozzle 10 of 3D printer for construction, a main pipe 30 parallel to the nozzle 10 is embedded in the nozzle 10, the main pipe 30 being a hollow pipe body having a transfer hole 33 formed in an axial direction therein;

• an exposed pipe 36 as a pipe body having the transfer hole 33 formed in an axial direction therein and exposed outside the nozzle 10 is formed;
• and
• the other end of the main pipe 30 at a distal end of the nozzle 10 is connected to the exposed pipe 36 via a curved pipe 34, such that as a filament material 31 introduced into the transfer hole 33 of the exposed pipe 36 is discharged from an end of the main pipe 30 at the distal end of the nozzle 10 via the main pipe 30, the filament material 31 may be co-printed with a printing material while embedded in the printing material.
