3D printing has brought about a worldwide manufacturing revolution,It used to be that the design of parts depends entirely on whether or not the production process can be realized,The emergence of 3D printers will overturn this production idea,which will allow enterprises to no longer consider production when producing parts. Process problems, any complex shape design can be achieved by 3D printer。
　　3D printing can generate objects of any shape directly from computer graphic data without the need of machining or dies, thereby greatly shortening the production cycle of products and increasing productivity. Although still to be improved, the market potential of 3D printing technology is huge, and it is bound to become one of the breakthrough technologies in the future manufacturing industry。
　　3D printing allows people to buy some electronic products such printers in shops,factories are direct sales. Scientists say that the use of three-dimensional printers is still limited,but people will be able to use 3D printers to print more useful items on a certain day in the future。
　　3D Printing Technology Is Crucial for NASA's Space Exploration Mission,More than 30% of the existing spare parts of the International Space Station can be manufactured by this 3D printer。This device will use polymers and other materials to make articles layer by layer using extrusion incremental manufacturing technology。The 3D printing experiment is one of the NASA's key research projects in the future。3D printed parts and tools will enhance the reliability and safety of space missions。At the same time, space mission costs can be reduced by not having to transport it from the earth。
