Composite 3D printer and printing method

Abstract

The invention provides a composite 3D printer. By arranging a work platform, a base and a portal frame, 3D printing work of a composite is achieved, and the composite 3D printer is simple in structureand small in size. A containing bottle is added on the basis of a single spray head, and a conveying device is additionally added. Due to the special structure of the containing bottle, soldering tinbecomes molten tin, and a container for storing a molten tin material and the molten tin are not likely to be subjected to a chemical reaction. A shell of the container for storing the molten tin material need to insulate heat, and air pressure in the container is accurately controlled. According to the composite 3D printer, a wire type material and a metal tin material can be applied at a time,two conveying devices correspond to a spray head and the containing bottle correspondingly, the two conveying devices alternately work, the problem that material printing is single is solved, and theproblem that the metal printing cost is high is relieved.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a composite material 3D printer and a printing method. Background technique [0002] 3D printing is a typical application of additive manufacturing technology.

Problems solved by technology

[0003] Fused deposition technology is one of the fastest-growing technologies in 3D printing technology. Traditional fused deposition 3D printers have relatively large limitations and cannot meet complex product design requirements.

The current desktop-level 3D printers based on fused deposition modeling can only print a single material, which has the disadvantages of single printing material, low printing accuracy, and high printing cost.
