3d printing,can have applications in which fields?

Israel's Objet believes that 3D printers are in high demand in industries including government, aerospace and defense, medical devices, high-tech, education, and manufacturing.　　Medical industry. An 83-year-old man suffering from a chronic bone infection was replaced with a jawbone "printed" by a 3D printer, the world's first case of a human skeleton made from 3D printed products.　　　Scientific research. Drexel University researchers through the fossil 3D scanning, the use of 3D printing technology to make a 3D model suitable for research, not only to retain all the external characteristics of the original fossil, but also to do the proportion of the reduction, more suitable for research.　　Product prototypes. For example, Microsoft's 3D model printing workshop, after the product is designed, the model is printed out by 3D printers, which enables the design and manufacturing department to better improve the product and create a better product.　　Artifact conservation. Museums often use many sophisticated alternatives to protect original works from environmental or accidental events, while replicas can also extend the impact of the art or artifact to more and more people. The Smithsonian, for example, used a giant 3D-printed replacement of the original Thomas Jefferson in the place of the original sculpture because it was going to be put on display in Virginia.　　Architectural Design. In the construction industry, engineers and designers have embraced building models printed on 3D printers as a method that is fast, inexpensive, and environmentally friendly while being beautifully produced. It fits the designer's requirements perfectly while saving a lot of material.　　Manufacturing. The manufacturing industry also needs a lot of 3D printed products, as 3D printing is much better than traditional manufacturing in terms of cost, speed and accuracy. The 3D printing technology itself is perfect for mass production, so there are so many benefits to utilizing 3D technology in the manufacturing industry that even quality control is no longer an issue.　　The food industry. That's right, "printing" food. Researchers are already trying to print chocolate. Perhaps in the near future, a lot of food products that look exactly the same will be "printed" using food 3D printers. Of course, by that time it will probably be many times more expensive to make food by hand.　　Car manufacturing. It's not that your car is printed on a 3D printer (but maybe someday it will be), but rather that the automotive industry is replacing non-critical parts with 3D printed products for safety testing and other tasks to reduce costs while pursuing efficiency.　　Accessories, jewelry. This is one of the broadest markets. In the future whether it's your personalized pen holder, a cell phone case with your half embossed, or a unique ring in the world that you and your loved one own, it's possible that it will be printed through a 3D printer. You don't even have to wait until the future to realize it.
