The 3D printing technology is a technology that builds an object by layer-by-layer printing using a powdery metal or plastic adhesive material based on a digital model file. Its most prominent advantage is that it can generate parts of any shape directly from computer graphics without the need for machining or any tooling. Even in the near future, if an organ is changed in order to get sick, there is no need to find a matching organ source. Just take some stem cell culture on the patient's body to become a printing material, and then print out exactly the same organ for transplantation. Rejection reaction.
According to Dr. Guo Chi, a 3D printing technology expert from the city, this technology has a wide range of applications. It can be used in cultural relics, in addition to previously reported manufacturing and medical fields. The city has developed two-dimensional photos to directly make 3D relief effect technology.
Guo Chi, director of the Rapid Manufacturing National Engineering Center Suzhou Sub-center, is a leader in domestic 3D printing technology. He said that 3D printing appeared in the 1980s and was referred to as "rapid manufacturing" or "additive manufacturing" technology. To Guo Chi's excitement, even the restoration of cultural relics can also use 3D printing technology. Guo Chi said that this is mainly through the use of this technology to make cultural artifacts, and then for reference when repairing artifacts. Because of the high printing accuracy, artifact models can also achieve very realistic results.
Suzhou has begun research on 3D printing technology, and its level is in the middle and upper reaches of the country's cities. Guo Chi told reporters that a Suzhou science and technology company has also recently developed a technique that directly makes 3D relief effects through two-dimensional photographs. At present, this technology has basically matured. As for the future of 3D printing technology, Guo Chi believes that it will develop in three areas.
The first is material. The available materials at this stage are relatively small, mainly polymer and titanium alloy materials. Guo Chi hopes to quickly develop new materials that are both durable and inexpensive.
The second is the increase in print speed and size. Guo Chi introduced that, at this stage, printing products with a height of 10 cm using 3D printing methods is basically more than 3 hours, and the largest international size can only be about 1.5 meters, and only about 1 meter in China.
The third is the development of low-cost homes. "3D printing technology will help many types of workers greatly reduce the amount of manual use, resulting in a new revolution in manufacturing!" said Guo Chiru.
Learned that Suzhou opened the first 3D printing photo gallery, Guo Chi is very happy. However, the development prospects of this industry in the end, Guo Chi believes remains to be seen. The reason is that 3D printing photo studio is a new thing after all, the equipment is expensive, the initial investment is relatively large, maintenance costs are also relatively large, "This will inevitably lead to higher service prices." Guo Chi believes that how many customers can accept this price is the key to determining the survival of the 3D printing studio.
