<p>The present invention relates to a 3D printer using a shaft linear motor, comprising: a worktable on which a 3D model is manufactured; a printing module for printing the 3D model on the worktable; and the shaft linear motor for printing, which linearly moves the printing module and/or the worktable, wherein the shaft linear motor for printing comprises: a stator unit which is provided in a linear movement direction of the printing module and/or the worktable so as to guide a linear movement of the printing module and/or the worktable and has a permanent magnet provided therein; a mover unit which is provided to cover the outer circumferential surface of the stator unit and linearly moves along the stator unit by means of electromagnetic force which is generated between the mover unit and the permanent magnet when current is applied; a frame unit having a coil accommodating space in which the mover unit is provided, and is connected to the printing module and/or the worktable so as to linearly move the printing module and/or the worktable according to the linear movement of the mover unit; and a fluid providing unit provided at one side of the frame unit so as to provide low-temperature fluid into the frame unit, thereby allowing the low-temperature fluid to flow into the inner space of the frame unit so as to cool heat generated from the stator unit and the mover unit.</p> |
