1. A nozzle of an auto-agitating 3D printer for construction,
wherein in the nozzle (10) of an auto-agitating 3D printer for construction, a main shaft (30) parallel to the nozzle (10) is embedded in the nozzle (10), a rotatable body (40) configured to freely rotate around the main shaft (30) as an axis is installed, and a part of the main shaft (30) is fixed to an inner circumferential surface of the nozzle (10); and
wherein on an outer circumferential surface of the rotatable body (40), a plurality of agitating blades (45) inclined relative to the main shaft (30) are radially formed around the main shaft (30), such that as a fluid printing material is discharged via the nozzle (10), the agitating blades (45) and the rotatable body (40) rotate around the main shaft (30) by their own power without an additional power.
