Masks are lacking under the epidemic, and 3D printers can produce masks to protect the epidemic. It is reported that to respond to the epidemic, the US Air Force's 388th Fighter Wing enabled 3D printing technology to make N95 masks. They used a synthetic material (nylon, plastic, and carbon fiber) on the 3D printer to make the mask. Each mask was composed of three independently printed parts, which were the mask body, the internal grid, and the outer cover where the filter material was placed. This N95 mask can be used repeatedly and can be disinfected with alcohol. Although the protective effect of 3D printed masks is not as good as traditionally produced masks, it is the right choice in the face of emergencies.
3D printing technology appeared in the mid-1990s and is the latest rapid prototyping device using light-curing and paper lamination. It works the same as ordinary printing. The printer contains liquid or powder "printing materials." After connecting to the computer, the "3D printing materials" are superimposed layer by layer under computer controled, and finally, the blueprint on the computer is turned into a physical object. This printing technology is called 3D printing.
Commonly printers used in daily life can print flat objects which is designed by computers, and the so-called 3D printers work the same as regular printers, except that the printing materials are somewhat different. The printing materials of ordinary printers are ink and paper, and the 3D printers are equipped with metal. The various "printing materials" such as ceramics, plastics, sand, etc. are real raw materials. After the printer is connected to the computer, the "printing materials" can be superimposed layer by layer through computer control, and finally, the blueprint on the network becomes In kind.
In layman's terms, the 3D printer is a device that can "print" real 3D objects, such as printing robots, printing toy cars, printing various models, and even food. The reasons why it is commonly referred to as a "printer" refers to the technical principles of ordinary printers because the layering process is very similar to inkjet printing.
The working principle of the 3D printing pen and the 3D printer is the same, both are to melt the material to shape new things, and the 3D printer needs to enter the program, the 3D printing pen is more by the user's operation, 3D painting.
3D printing is more like a concept, "printing" the work through layered processing to directly become a 3D three-dimensional model. It has a wide range of consumables. Common materials include nylon glass fiber, durable nylon material, gypsum material, aluminum material, titanium alloy, stainless steel, silver plating, gold plating, rubber materials, etc. The use of these materials also means that different needs Type of technical capabilities. The 3D printing pen uses one of the 3D printing fused deposition technologies. The consumables also use plastic raw materials relatively singly, including three types of ABS, PLA and PCL.
