Abstract: Disclosed is an apparatus for horizontally aligning a bed of a three-dimensional printer, the apparatus enhancing quality of a 3D object produced on the bed, by tilting the bed on two axes so as to horizontally align the bed before operating the three-dimensional printer. The three-dimensional printer produces the 3D object by depositing materials on the bed with an extrusion head, the apparatus including a tilting unit tilting the bed on two axes to horizontally align the bed, when the bed is not horizontal.
