Disclosed are a multifilament-supplying extruder for a three-dimensional printer and a three-dimensional printer applying the same. According to an embodiment of the present invention, multifilament-supplying extruder for the three-dimensional printer comprises: a hop bolt having a plurality of grooves corresponding to each raw material; and a selection part for tightly sticking the raw materials onto one of the grooves selectively. As the hop bolt rotates, raw material selected from the raw materials by the selection part can be transported by being closely sticked to the corresponding groove. |
