Abstract

The invention discloses a novel 3D printing bar material extrusion mechanism, which includes a driving gear and a driven gear, the driving gear and the driven gear mesh with each other, the driving gear is installed on the first device, and the driven gear is installed on the second device , the structure of the first device is consistent with that of the second device, both including a synchronous belt, a top synchronous wheel and a bottom synchronous wheel; the upper end of the first device and the second device is provided with a positioning sleeve, the lower end is provided with a heating device, and the bottom of the heating device is provided with a nozzle. The invention realizes the self-adaptation of the size of the bar material within a certain range, and ensures the continuous transmission and extrusion of the multi-section bar material, so as to ensure the adaptability and continuity in the actual printing process, lay the foundation for automatic feeding, and Improve the application range of materials for fused lamination molding 3D printing technology.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a novel 3D printing bar extrusion mechanism. Background technique [0002] The traditional FDM 3D printing technology (FDM) is to heat and melt the filamentous hot-melt material, and at the same time, under the control of the computer, the three-dimensional nozzle selectively coats the material on the workbench layer by layer according to the cross-sectional profile information. superior. In theory, materials that can be heated and melted and cooled and solidified are suitable for this technology. However, the raw material used is filamentary wire, which usually needs to be wound on a circular material tray. Therefore, at this stage, the raw materials that can be printed by this 3D printing technology are mostly thermoplastic polymer materials with certain elastic plasticity. Other materials that do not have excellent elastoplasticity often need to be mixed with t...
