3D (three-dimensional) printing metal melt conveying device

Abstract

The invention relates to a 3D (three-dimensional) printing metal melt conveying device, which comprises a furnace body, a sealing furnace cover, an air pressure device, a discharging pipe, a graphite melt conveying pipe and an atomizer, wherein the sealing furnace cover is arranged on the furnace body in a covering way, the air pressure device is communicated with an inner cavity of the furnace body through an air inlet pipe, a heating body is arranged on the inner wall of the furnace body, the graphite melt conveying pipe is arranged outside the furnace body and is communicated with the discharging pipe arranged in the furnace body, the discharging pipe extends into the bottom of the furnace body, and the output end of the graphite melt conveying pipe is communicated with an inner cavity of the atomizer. The 3D printing metal melt conveying device has the advantages that the air pressure is adopted for conveying the metal melt into the atomizer, one atomizer is omitted, the blockage of the atomizer is avoided, meanwhile, the flow rate of the metal melt is stable and adjustable, and the quality of obtained products is better.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing metal melt conveying device. Background technique [0002] 3D printing (3D printing), a type of rapid prototyping technology, is based on digital model files, using bondable materials such as molten metal (alloy), powdered metal (alloy) or plastic, through layer-by-layer The technique of constructing objects by means of printing. The biggest feature of this technology is that it can create objects of almost any shape. It has become an international and domestic frontier research field. [0003] 3D printing is usually achieved using digital technology material printers. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. There are already parts printed using this technology. Based on the computer three-dimensional design model, thro...

AI Technical Summary

Problems solved by technology

This type of printer needs to use two atomizers, the structure is relatively complicated, and the equipment cost is high. Both atomizers must be fed with high-pressure gas, which greatly wastes resources. In addition, the metal melt enters the atomization due to gravity. In the device, it often leads to blockage of the atomizer and requires regular maintenance
