Liquid metal 3D prints multi-functional shower nozzle

Technical Field

The utility model relates to a metal 3D prints the field, especially relates to a liquid metal 3D prints multi-functional shower nozzle.

Background

At present, 3D is one of rapid prototyping technologies, which is a technology for constructing an object by using an adhesive material such as powdered metal or plastic and printing layer by layer on the basis of a digital model file. 3D printing is typically achieved using digital technology material printers. The method is often used for manufacturing models in the fields of mold manufacturing, industrial design and the like, and is gradually used for directly manufacturing some products, and parts printed by the technology are already available. The technology has applications in jewelry, footwear, industrial design, construction, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields. The 3D printing technology is present in the mid-90 s of the 20 th century and is actually the latest rapid prototyping device using technologies such as photocuring and paper lamination. The printing machine is basically the same as the common printing working principle, the printing machine is filled with liquid or powder and other printing materials, the printing materials are overlapped layer by layer under the control of a computer after being connected with the computer, and finally, a blueprint on the computer is changed into a real object. The printing technology is called as 3D three-dimensional printing technology, along with the more mature 3D printing technology, the technology is also applied to various industries, when 3D printing is carried out through liquid metal, high-temperature liquid metal is sprayed out through a spray head to be printed, along with the printing, a certain amount of liquid metal remains in the spray head, and the liquid metal solidifies into blocks after the temperature is reduced to cause the blockage of the spray head, when the liquid metal is used again, the spray head can be continuously used after long-time heating is needed to melt the metal, so that the printing efficiency is reduced, the energy consumption is increased, and the heat dissipation of the printed metal part by the existing metal 3D printing equipment is generally carried out in a blade type mechanical fan mode, the heat dissipation efficiency is not high, and because power is provided by a motor, noise is generated, and the noise is increased when the fan runs for a long. Due to the adoption of a mechanical structure, the occupied space is large, and the installation near the 3D printing head with a narrow space is inconvenient. The other problem of the blade type fan installation is that the blowing direction is fixed, only heat dissipation can be carried out in a single direction, and heat dissipation cannot be carried out in the 360-degree direction around the printing head, so that the problem of uneven heat dissipation exists, and moreover, the blade type mechanical fan only has a single heat dissipation function and cannot carry out dust removal and purification treatment on the air inside the 3D printer.
