Embodiment Construction

[0045] Each part of the high-frequency induction fusion direct manufacturing printer HFDM of the present invention will be described separately.

[0046] HFDM is composed of control computer 1, high-frequency induction melting 3D printing box frame 2, melting high-frequency signal generator 3, workpiece heating device 4, gas pipeline 5 and power supply 6, etc.

[0047] The control computer 1 is a master-slave computer system. The master computer collects the information of each sensor single-chip microcomputer, and performs synchronous control on each component through each execution single-chip microcomputer to realize the 3D printing function. Due to the powerful functions of the current computer, the support of the cloud computer system, and the intelligence and integration of various sensors and execution components, the control computer 1 is diversified.

[0048] High-frequency induction fusion 3D printing box frame 2 has various implementation methods according to the si...

Abstract

The invention discloses a 3D (three-dimensional) printing machine adopting a high-frequency induction heating type to melt a metal material. The metal material in a coil is subject to induction heating through a high-frequency signal, and is melted into liquid or semi-liquid metal, the liquid metal is sprayed to a processing platform by a printing head, and the liquid metal is scanned, melted and directly formed drop by drop. The 3D printing machine has the advantages that by adopting the inert gas protective welding type, when the printing metal is welded, the splashing, oxidizing and deformation are avoided, the result is dense, and a high-quality 3D printing component is directly formed; the printing machine can be applied to the 3D printing of several-kilogram small metal components, and can also be applied to the direct forming 3D printing of several-ton metal components.

Description

technical field [0001] The invention relates to a metal 3D printer, specifically, a metal 3D printer that adopts high-frequency induction melting. Background technique [0002] 3D printing technology is different from the traditional mechanical processing 'subtractive molding', but layered processing 'additive molding' process, although 3D printing technology still has problems, but it has a variety of technologies, and it is close to maturity, it will detonate the third industrial revolution. [0003] The basic part of a 3D printer is that the printing head sprays the printing material onto the printing workpiece of the printing platform, or it is formed by selectively solidifying and fusing the powder layer by layer; and the relative 3D (3D) sports. [0004] The mainstream technologies of 3D printing include SLA, FDM, SLS, 3DP, LOM, etc. In SLA, liquid photosensitive plastic is printed and cured by ultraviolet radiation; To form the surface, pile up layer by layer; SLS ...
