PORTABLE 3D PRINTER

The present invention relates to a portable 3D printer comprising: a frame member including a detachable frame and having a cuboid shape; a nozzle member, which is provided at the upper part of the frame member and extrudes filaments; a plurality of horizontal rod members provided at an upper part of the frame member so as to penetrate into the nozzle member, and formed such that the nozzle member moves in the X direction; a printing bed member provided at a lower part of the frame member and having the filaments stacked thereon; a plurality of vertical rod members provided at the lower part of the frame member so as to penetrate the printing bed member, and formed such that the printing bed member moves in the Z direction; and a support member provided inside the frame member and connecting the frame member in the X direction and the Z direction, and thus the present invention allows easy assembly and disassembly of the frame of the 3D printer, thereby reducing assembly and disassembly time and being efficient. In addition, the present invention is light and easy to carry since the material of the frame of the 3D printer is made from plastic, carbon, and the like. Furthermore, the present invention has an inexpensive price range and is suitable for an educational use since metal is not used for the material of the 3D printer frame. Moreover, present invention is conveniently carried since the frame of 3D printer is detachable. La présente invention concerne une imprimante 3D portable comprenant : un élément de cadre comprenant un cadre détachable et ayant une forme cuboïde ; un élément de buse, qui est disposé au niveau de la partie supérieure de l'élément de cadre et extrude des filaments ; une pluralité d'éléments de tige horizontaux disposés au niveau d'une partie supérieure de l'élément de cadre de façon à pénétrer dans l'élément de buse, et formés de telle sorte que l'élément de buse se déplace dans la direction X ; un élément de lit d'impression disposé au niveau d'une partie inférieure de l'élément de cadre et ayant les filaments empilés sur celui-ci ; une pluralité d'éléments de tige verticaux disposés au niveau de la partie inférieure de l'élément de cadre de façon à pénétrer dans l'élément de lit d'impression, et formés de telle sorte que l'élément de lit d'impression se déplace dans la direction Z ; et un élément de support disposé à l'intérieur de l'élément de cadre et reliant l'élément de cadre dans la direction X et la direction Z, et ainsi
