A 3D printer according to an embodiment of the present invention comprises: a water tank casing having an accommodating space therein; a nozzle unit disposed to be upwardly and downwardly moved in the accommodating space of the water tank casing, and spraying and laminating a modeling material for modeling a 3D sculpture; and a control unit for controlling the nozzle unit. A support liquid for supping a 3D sculpture laminated by being modeled is disposed in the accommodating space of the water tank casing. A loss of a modeling material is reduced, and time and costs are saved. Also, a 3D sculpture may be stably supported when being modeled. |
