3D printing (3D prinTIng), also known as additive manufacturing technology, a type of rapid prototyping technology, is a digital model file-based technology that uses bondable materials such as powdered metals or plastics to construct objects by printing them layer by layer and curing them cumulatively, layer by layer.
The application of 3D printing in nine major fields
In the architectural industry, engineers and designers have embraced the use of 3D printers to print architectural models, a method that is fast, inexpensive, environmentally friendly, and at the same time beautifully produced. It fits perfectly with the designer's requirements, while saving a lot of material.
Xi'an Red Society Hospital realized the first case of porous titanium bone implant prosthesis in Northwest China with the help of 3d printing technology to treat patients with ankylosing spondylitis for fracture dislocation.
Xi'an Fourth Hospital completes difficult replacement of shoulder joint with "customized" 3D printing
The First Affiliated Hospital of Xi'an Jiaotong University set up a 3D printing medical research and application center, marking the combination of medical industry and strong cooperation of the 3D printing medical research and application center officially settled in Shaanxi.
It's not that your car is printed by a 3D printer (of course maybe one day this is possible), but that the automotive industry will replace some non-critical parts with 3D printed products when conducting safety tests and other work, reducing costs while pursuing efficiency.
Traditional manufacturing also needs a lot of 3D printed products because 3D printing is much better than traditional manufacturing in terms of cost, speed and accuracy. And 3D printing technology itself is very suitable for mass production, so manufacturing industry can bring a lot of benefits by using 3D technology, even quality control is no longer a problem.
By 3D scanning fossils, researchers at Drexel University in the United States have used 3D printing technology to make 3D models suitable for research that not only retain all the external features of the original fossil, but also do scale down to be more suitable for research.
For example, Microsoft's 3D model printing workshop, after the product is designed, the model is printed out by 3D printer, which enables the design and manufacturing department to improve the product better and create a better product.
3D printing technology is important in restoring and preserving history and culture, restoring the authenticity of cultural relics, recording the history of these relics that once suffered from extinction, and effectively avoiding the erasure of human historical memory.
For example, the Terracotta Warriors and Horses of the First Emperor of Qin in Xi'an, which had just been unearthed with bright colors and lifelike expressions, have long lost their elegance when they were first unearthed, and are now severely weathered, with their vivid colors disappearing and dull as yellow clay.
Food industry, researchers have begun to try to print chocolate. Perhaps in the near future, many look identical food is the use of food 3D printer "print" out. Of course, at that time may be artificially produced food will be many times more expensive.
This is one of the most extensive market. In the future, whether it is your personalized pen holder, or your half body embossed cell phone shell, or you and your loved ones have the world's unique ring, are likely to be printed out through the 3D printer. Do not even have to wait for the future, now can be achieved.
