Five-channel remote spinning color mixing 3D printer

Abstract

The invention provides a five-channel remote spinning color mixing 3D printer. A rack support of the printer slides front and back along sliding rails on the two sides of a base, a feeding device is installed at the top of the support, a spray head assembly is installed on a cross beam of a double-screw lifting mechanism and moves in the Z direction and the Y direction in the support, a carrier platform moves in the X direction along sliding rails on the two sides in the base, and the feeding device is connected with the spray head assembly through a pipeline. Raw materials in multiple colorsare cooled through a plurality of coolers firstly and then are led to enter a heating cavity through guide pipes via remote spinning consumable items, and the raw materials are stirred through a stirring stick. The problems that a present table top grade printer is poor in structure stability, printed products are single in forming color, colors needed by the products cannot be accurately obtained, mixing is uneven, and color differences exist are solved; and stirring devices are additionally arranged in the feeding and discharging processes to achieve sufficient mixing of the raw materials, and a series of issues brought by insufficient mixing of PLA materials are avoided.

Description

technical field [0001] The invention relates to a five-channel remote spinning and color mixing 3D printer, which belongs to the technical field of 3D printing devices. Background technique [0002] As human society enters the 21st century, science and technology develop rapidly, and the development of material forming technology is particularly rapid. 3D printing forming technology, as an emerging technology that was born at the end of the last century and developed rapidly after entering the 21st century, shows great application value and broad market prospects. Because of its high production efficiency, full utilization of raw materials, low requirements for operators, designers can directly make samples, and good confidentiality, it is widely used in various fields, such as machinery manufacturing, aerospace, construction, home furnishing, Medical equipment, engraving and other industries. [0003] With the continuous improvement of people's living standards and the co...

Problems solved by technology

[0005] The present invention aims to solve the problem that the current desktop-level FDM3D printers have poor structural stability, the color of the printed product is single, and the existing multi-color printers use the way of heating and mixing the nozzles to color the color, which cannot accurately obtain the color required by the product, and there will be inaccurate mixing. In order to solve the problem of uniformity and color deviation, a five-channel remote spinning and color mixing 3D printer is proposed, and a stirring device is added during the feeding and discharging process to achieve full mixing of raw materials and avoid a problem caused by the full integration of PLA materials. series of questions
