Improved nonmetal 3D printer

The invention discloses an improved non-metal 3D printer, and belongs to the field of printer design, the improved non-metal 3D printer comprises a printing room, a printing head is movably arranged in the printing room, a workpiece forming plate is installed in the projection plane range of a printing head moving area, and the workpiece forming plate has the freedom degree of moving inside and outside the printing room through a swing mechanism; the swing mechanism is movably provided with a lifting rod capable of being adjusted up and down, one end of the lifting rod is connected with the workpiece forming plate, and the other end of the lifting rod is movably connected with a driving mechanism which drives the lifting rod to move. Molded workpieces are transferred inside and outside the printing room through the swing mechanism, observation of the workpieces in the workpiece production process is facilitated, the workpieces are transferred out of the printing room, the driving mechanism controls the liftin
