3D printing device and method free of supporting liquid phase mixed materials

Abstract

The invention relates to a 3D printing device and method free of supporting liquid phase mixed materials, and belongs to the technical field of 3D printing. A container is fixed to a base; a Y-axis motion drive is fixed to the base; a Z-axis motion drive is connected to a sliding block of the Y-axis motion drive through a screw; an X-axis motion drive is connected to a sliding block of the Z-axismotion drive through a screw; a printing spray head is connected to a sliding block of the X-axis motion drive through a connecting block and a screw; three feeding openings of the printing spray headare connected to three sets of feed systems through guide pipes correspondingly; and a gas inlet opening is connected to a gas supply system through a guide pipe. The 3D printing device and method have the advantages that the structure is novel; the material range of 3D printing is widened, and the 3D printing device and method can be suitable for flexible materials and bioactive materials; the process of printing supporting materials is omitted; the time of removing a supporting structure and printing raw materials are saved; the process that materials need to be pre-mixed before printing isomitted; the printing time is saved; the feed quantity of the raw materials is precisely controlled; and the raw materials are mixed sufficiently and evenly.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing device and method of an unsupported liquid-phase mixed material. Background technique [0002] With the continuous development of 3D printing technology, 3D printers have been widely used in various industries such as manufacturing, medical treatment and education. Printing materials have also expanded from single ABS and photosensitive resins to various functional materials such as metals and biological tissues. However, the traditional 3D printing nozzle can only realize the input and output of a single material. The material needs to be prepared in advance before printing. Many materials will fail soon after mixing, which increases the difficulty of printing operations and wastes raw materials. Moreover, the traditional 3D printing technology needs to add support materials during printing. After printing, the support materials are difficult to re...
