In fact, as of now, there is no real medical 3D printing company in China, but general technology. AOD is very optimistic about the medical 3D market, Liu Yuan said: "In the medical special project, AOD has established a team of 30 people, and will gradually become the hospital's just need in the future."
In addition to the backwardness of technology, the main factors causing China's 3D printing industry to fall behind in developed countries, policy supervision and industry standards have become the first factor.
Wu Zhanming told the 21st Century Business Herald: "In the second half of 2014, the CFDA issued a document stating that medical 3D printing products must pass verification and registration, but there is currently no product that has obtained a registration certificate. In this case, we can only Do something that does not require verification of a registered product or a class of medical devices."
Wu Zhanming predicts that there will be no medical registration products in China within one year. “Because there is no industry standard yet, there is no verification registration without standard.”
The second biggest obstacle facing medical 3D printing is cross-border integration. Many companies interviewed said: "This industry needs to integrate IT, equipment, materials, medical and other disciplines."
The source of materials is the third major difficulty commonly reflected by 3D printing companies. “China is a big country in titanium production, but at present, there are very few companies specializing in the production of titanium powder for 3D printing, and the gap between product quality and foreign countries is large, and the enthusiasm of production is also Not high.” Dai Kezhen, for example, takes the titanium mesh commonly used in neurosurgery as an example. The price of imported products is more than 10,000 yuan. Titanium mesh is also very suitable for 3D printing, but the upstream titanium powder supply is in a blank state.
In addition, the technical difficulty in front of medical 3D printing companies in the world is that the printing speed is too slow. "The technology used in 3D printing is a layer-by-layer stacking printing method, and most of them are trials of dual-head printers, and the speed is difficult to increase. This is also the world. The common problem facing the 3D printing industry." Liu Yuan said.
