The present invention relates to an expandable 3D printer and, more specifically, to an expandable 3D printer, which comprises: a frame (10) for forming a cuboid shape by four vertical frame members (16, 17, 18, 19) and horizontal frame members (12, 13) connected among vertical frame members (16, 17, 18, 19); a pair of X-directional guide rods (20, 21) parallel extended by being separated from each other, and a pair of Y-directional guide rods (30,31) parallel extended by being separated from each other; and a support bearing (15) for supporting each of the end units of the guide rods (20, 21, 30, 31). According to the present invention, the assembly is relatively easy by simplifying the structure of the head installed with the nozzle. |
