Disclosed is an ascent and descent apparatus for a liquid material spray printer, which may control a distance between a subject and a spray assembly optimally. The apparatus includes a sliding member having a pair of sliders selectively reciprocating oppositely by a driving unit; a frame installed above the sliders and having an elongated guide hole corresponding to a reciprocating range of the sliders; and a pair of crosslink members installed to an upper surface of the frame to couple with the sliders through the hole and whose upper end supports a flat table. The crosslink members include a pair of unit links hinged at their substantial center, whose lower ends are respectively coupled to the slider and hinged to the frame, and upper ends are respectively hinged to the flat table and supports the flat table rotatably, whereby the flat table is lifted by reciprocation of the sliders.
