Metal 3D printer using atomized metal as consumable

Abstract

The invention discloses a metal 3D printer using atomized metal as a printing material. The metal 3D printer comprises a 3D printing unit, a metal atomization control unit, a control unit, a cooling system, a mist extractor, and a finished workpiece automatic-discharging unit. The 3D printing unit comprises a workbench, a servo motor, a rotational structure, an atomized metal spray nozzle, a liquid conveying pipe, a heater and a cooler, wherein the atomized metal spray nozzle is connected with an atomizing chamber through the liquid conveying pipe. The metal atomization control unit comprises a smelting furnace, an atomizing furnace, a thermocouple sensor, a liquid conveying tube and a melt valve, wherein the smelting furnace is connected with the atomizing chamber through the liquid conveying tube. The finished workpiece automatic-discharging unit comprises an electric automatic door and a workpiece finished product box and is used for automatically discharging finished workpieces. According to the invention, ultra-micro metal powder is not required, the kinds of selectable metal are multiple, appearance accuracy of printed metal devices is guaranteed, and the purpose that multiple metal materials which are randomly distributed are printed simultaneously can be achieved through simple improvement; in addition, due to the fact that a workpiece automatic-discharging structure is used, the function that the printer in a no-man control state can continuously print multiple models is achieved.

Description

technical field [0001] The invention relates to a metal 3D printer using atomized metal as a consumable material, which belongs to 3D printing equipment. Background technique [0002] 3D printing (3D Printing) was first proposed by Jim Bred and Tim Anderson of the Massachusetts Institute of Technology. They designed a device that can bond powder based on an ordinary inkjet printer, which became the earliest 3D printer. In March 2009, at the Roadmap for Additive Manufacturing (RAM) Workshop held in Washington, USA, it was officially determined to use the term Additive Manufacturing (AM) to refer to 3D printing technology. And made a plan for the development of rapid prototyping technology in the next 10 years. At present, the main lamination manufacturing technologies include Selective laser sintering (SLS), Stereolithography (SLA), Fused Deposition Modeling (FDM), etc. Its basic principle is stacked manufacturing. The rapid prototyping machine forms the cross-sectional sha...

Problems solved by technology

[0003] 3D printing is a rapidly expanding emerging market, but there are obvious barriers to metal 3D printing that hinder its rapid growth

Furthermore, the laser head is expensive, and can only print a single metal powder, and cannot achieve simultaneous printing of multiple metals in any distribution.
