Three-dimensional printer provided with supply devices equipped with magnetic filter screens

Abstract

The invention discloses a three-dimensional printer provided with supply devices equipped with magnetic filter screens. The three-dimensional printer comprises a case, a controller, a moving rack, a printing port unit, a printing platform and supply devices, wherein the controller is electrically connected with the moving rack to control the moving rack to move above a printing area; the supply devices are connected with the printing port unit to heat and fuse raw materials and jet the materials to the platform for forming; the printing port unit comprises a printing disc and a plurality of printing heads, and discharging ports of the printing heads vertically face the printing platform; the supply devices are assembled in one-to-one correspondence with the printing heads so as to add different colors of the raw materials to the different printing heads; each supply device comprises a supply barrel, a collector and a supply pipe, the collector is arranged at the bottom end of the supply barrel and conveys the raw materials through the supply pipe, and one magnetic filter screen is arranged in the supply barrel and detachably erected at a joint of the collector and the supply barrel. The supply devices can remove metal impurities from the plastic raw materials added to the three-dimensional printer, the raw material cleanliness is improved, and high quality of the three-dimensional printed products is guaranteed.

Description

technical field [0001] The invention relates to three-dimensional printing equipment, in particular to a three-dimensional printer with a magnetic filter mesh feeding device. Background technique [0002] A three-dimensional printer is a device based on a digital model that uses molding materials such as powdered metal or plastic to construct three-dimensional objects by layer-by-layer printing. [0003] The printing raw materials of the existing 3D printers are all plastic material tapes, which have high cleanliness and good printing effect, but the cost is relatively high, and the existing printing machines cannot realize the waste utilization of raw materials. At the same time, in order to print out colored three-dimensional objects, at least a variety of raw material tapes of different colors need to be provided to the three-dimensional printer. The overall volume increases. Moreover, during the printing process, the demand for various raw materials is dynamically chan...

[0003] The printing materials of existing 3D printers are all plastic tapes, which have high cleanliness and good printing effect, but the cost is high, and the existing printing machines cannot realize the waste utilization of raw materials

At the same time, in order to print out colored three-dimensional objects, at least a variety of raw material tapes of different colors need to be provided to the three-dimensional printer. overall volume increase

Moreover, during the printing process, the demand for various raw materials is dynamically changing, resulting in frequent replacement of raw material boxes, which not only prolongs the time for 3D printing, but also makes the printing effect of different color transitions poor, affecting the final quality of the printed product.
