The present invention relates to a 3D printer including a horizontal sensor unit and more specifically, to a 3D printer including a horizontal sensor unit, which operates a sensor unit without a separate motor required for bending or spreading a sensor to reduce production cost and maintenance cost of the 3D printer. To this end, the 3D printer of the present invention includes: a frame; a work table provided on the frame; a nozzle unit for depositing a molding material on the work table while extruding and spraying the same to make a 3D form; an X axis unit for moving the nozzle unit in a left-right direction; a Y axis unit for moving the nozzle unit in a front-back direction; and a Z axis unit for moving the nozzle unit in an up-down direction, wherein the nozzle unit further includes a horizontal sensor unit and the horizontal sensor unit includes: a sensor base provided with a horizontal guide; a horizontal bar coupled to the horizontal guide so as to move in the left-right direction; a sensor bar perpendicular to the horizontal bar downward or bent in the horizontal direction upon left or right movement of the horizontal bar; and a horizontal sensor provided at an opposite end of the sensor bar. |
