Functional continuous wire parallel type composite 3D printing device and printing method thereof

Abstract

The invention provides a functional continuous wire parallel type composite 3D printing device and a printing method thereof. The functional continuous wire parallel type composite 3D printing device comprises a heating assembly, as well as a base layer printing nozzle, a functional continuous wire printing nozzle and a covering layer printing nozzle which are arranged on the heating assembly according to the printing sequence, wherein the base layer printing nozzle is mounted on the heating assembly and used for laying a base layer material on a printing platform; the functional continuous wire printing nozzle is mounted on the heating assembly and used for laying functional continuous wires on the base layer material, and a tensioning assembly is arranged in the functional continuous wire printing nozzle; and the covering layer printing nozzle is mounted on the heating assembly and used for laying a covering layer material on the functional continuous wires and the base layer material. According to the functional continuous wire parallel type composite 3D printing device, the base layer material and the functional continuous wires are covered with the covering layer material, so that overprinting of different assemblies in parts can be achieved; and an additive mode serves as a technological means, so that the continuity and sealing performance of printing materials are enhanced.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a functional continuous filament side-by-side composite 3D printing device and a printing method thereof. Background technique [0002] 3D printing, also known as additive manufacturing, is a process that adopts a different processing route from traditional subtractive manufacturing. By adding materials and manufacturing layer by layer, and based on 3D model data, it directly manufactures 3D physical objects that are consistent with it. Due to its high manufacturing flexibility, the physical process method plays an important role in industrial production and daily life. [0003] Composite materials are materials with new properties composed of two or more materials with different properties at the macro or micro level, and their comprehensive properties are often better than those of the original constituent materials. Fiber-reinforced composite materi...
