Embodiment

[0017] Example: such as figure 1 and figure 2 A 3D metal printer shown.

[0018] The print head integrating ceramic melting furnace and liquid metal injector is the key technology of this 3D printer:

[0019] The print head is made of high temperature resistant ceramic or graphite material, the outer layer is equipped with a water-cooled electric eddy current coil 19, the melting furnace is filled with inert gas to protect the liquid metal, and the injector is a reciprocating plunger pump. The water-cooled eddy current coil is fed with high-frequency current, and the heating power can be adjusted by the high-frequency controller according to the material type, model requirements, processing speed and other factors. The reciprocating frequency of the plunger pump plunger is adjusted according to the nonlinear function with the XYZ direction speed of the workbench, and the eddy current heating coil on the plunger pump is turned on or off according to factors such as shutdown,...

Abstract

The invention discloses a three-dimensional (3D) metal printer. A printing head integrating a ceramic melting furnace and a liquid metal ejector is a key technology for the 3D metal printer. The printing head is made of high temperature resistant ceramic or graphite material, a water cooling eddy current coil is installed on an outer layer, the melting furnace is filled with inert gas to protect liquid metal, and the ejector is a reciprocating type plunger pump. The water cooling eddy current coil is electrified with high-frequency current, and heating power can be adjusted through a high-frequency controller according to factors such as material types, model requirements and processing speeds. The inert gas keeps a certain pressure while protecting the molten metal, flow of the liquid metal is facilitated, and metal residue in the plunger pump and the melting furnace is removed by means of gas simultaneously during shutdown. Besides application to the 3D metal printer, the printing head can also be used for devices for die-cast molding and injection molding of metal material and the like.

Description

technical field [0001] The invention relates to the fields of three-dimensional printers and numerical control processing, in particular to a 3D metal printer. Background technique [0002] 3D printing, also known as three-dimensional printing, is a type of rapid prototyping technology that uses bondable materials such as powdered metal or plastic to construct parts through layer-by-layer multi-layer printing. The technology is used in mold making, industrial design and even product manufacturing, and some high-value applications (such as hip joints or teeth, aircraft parts) have printed parts. [0003] The most prevalent 3D printing technologies are SLS, FDM and SLA. Among them, SLS and FDM use melting or softening raw materials to produce laminates. 3D printing technology can use many kinds of materials, such as ABS plastic, PLA, nylon, glass filled polyamine, light curing materials, silver, titanium, steel, wax, dry film and polycarbonate. FDM is a melt extrusion moldi...
