Hand-held small-sized 3D printer

Abstract

The invention discloses a hand-held small-sized 3D printer which comprises a base, a printing platform and a lifting bracket, wherein the Z-axis lifting motor and a lifting guide rail are arranged at the top of the base; the Z-axis lifting motor is connected with a lifting screw, the lifting guide rail and the lifting screw both penetrate through the lifting bracket, a handle is arranged at the top of the lifting guide rail, the lifting bracket is connected with a first horizontal support rod, a second horizontal support rod, a mobile plate, an X-axis mobile motor, a horizontal support plate and a first annular gear driving belt, one edge of the first annular gear driving belt penetrates through the mobile plate, and the mobile plate is provided with a vertically arranged printing head; the printing platform comprises a bottom plate; and the bottom plate is connected with a first polished rod, a second polished rod, the printing platform, a Y-axis mobile motor and a second annular gear driving belt, and the upper edge of the second annular gear driving belt is arranged in the printing platform in an embedded manner. The hand-held small-sized 3D printer disclosed by the invention has the advantages of compact structure, small size, portability, convenience for carrying and high accuracy of Z-axis direction lifting and X-axis direction motion of the printing head.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a portable small 3D printer. Background technique [0002] 3D printers belong to rapid prototyping equipment and are currently in the early stage of rapid development. People are trying to use 3D printers as widely as possible; portable 3D printers are easy to carry and can be used at any time, and have a wider range of applications; the current portable 3D printers It is in the research and development stage, so the various structures that can realize the portable function of the portable 3D printer have certain novelty; the traditional 3D printer is used to realize the lifting movement of the print head at both ends of the lifting bracket. Drive mechanism, so the weight of the whole printer is relatively large, and its portability is poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a portable small 3D prin...
