Abstract

The invention discloses a spray type 3D printing device and method based on a composite material, and belongs to the technical field of 3D printing. The problem that many internal defects of a 3D printing product in the prior art exist is solved. Powder of an object to be printed is thoroughly mixed through a mixing system, then raw materials are fully melted through a dispersion system, a meltingsystem and a cooling system, and printing is completed by an atomizing spray head after dispersion even distribution is carried out; a heating chamber in the spray head heats and melts a wire in a molten throat pipe, complete melting of the wire is further ensured, and liquid can stably flow after melting; and in addition, air pressure in an air supply passage is accurately controlled, the size and shape of jet nozzles of the spray head are intelligently selected according to the object to be printed, one from point spray, line spray and surface spray can be selected according to the conditions, uneven temperature release in the printing process is reduced, the influence of material stress is eliminated, the warpage of time is eliminated, the defects are reduced, and the processing efficiency is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of 3D printing, in particular to a spray-type 3D printing device and method based on composite materials. 【Background technique】 [0002] 3D printing technology is regarded as the technical support of the third industrial revolution. Its technology does not require traditional tools, fixtures, machine tools or any molds, and directly converts the required model into a computer 3D model automatically, quickly, directly and accurately. Physical model, thereby effectively shortening the product development cycle. [0003] In the existing 3D printing, the accuracy and efficiency of printing size are contradictory, and there are often problems of low efficiency, insufficient melting and many defects. On the one hand, the loss of materials and time will directly affect the production cost and production cycle; on the other hand, if these defects cannot be detected in time, it will bring many safety hazards, esp...
