A hot review of the week: How hot is biological 3D printing?

Some time ago, when Premier Li Keqiang put 3D printing on the State Council symposium, the focus of attention was whether 3D printing could hope to subvert traditional manufacturing. Nowadays, with the continuous breakthrough of technology, 3D printing has begun to show a higher value of use - for medical assistance. As a result, a new hot noun began to sweep the traditional medical field - bio 3D printing.

In recent years, the global 3D medical printing market is rising year by year. According to statistics, the global 3D printing market in 2014 was about $6 billion, with a compound annual growth rate of 73% in the last three years, and the average annual growth rate of the 3D printing medical application market will remain above 25% in the next three years. The scale is over 10 billion.

In this regard, Mr. Rogers, the founder of Quantum Fund and a world-renowned investor, said: " 3D bio-printing technology will not only have vital scientific research value in the future, but also have corresponding market value. In the United States and even global capital markets, 3D concepts, The concept of biomedicine and the concept of intelligent manufacturing have always been investment hotspots, and 3D bioprinting covers many of the above disciplines. Its high-tech characteristics and life science concepts will become the focus of future investment. It will be for tissue engineering, regenerative medicine and medical research. A revolutionary breakthrough."

A hot review of the week: Bio 3D printing has achieved great success

In the past week, 3D printing technology at home and abroad has made great achievements in the medical field, and a subversive revolution in traditional medicine has come to the fore.

1. Hebei completed the world's first TPS plan + 3D print template lung cancer particle implantation

Conventional lung cancer particle implantation is mostly guided by CT-guided or normal template-guided implantation, and most of them have no intraoperative TPS plan. The doses of preoperative and postoperative TPS are difficult to be consistent, which is likely to cause cold spots or hot spots. The internationally recognized difficulty in restricting the implantation of lung cancer particles is also the hottest research topic.

Recently, Wang Juan, director of the Department of Oncology, People's Hospital of Hebei Province, after years of hard work, successfully completed the world's first intraoperative TPS plan + 3D print template lung cancer particle implantation. The success of this operation not only created a new era of accurate treatment of lung cancer particle implantation, but also fully proved that the particle implantation technology of Hebei Provincial People's Hospital has reached the international leading level.

2, 3D printing human living cells are expected to achieve transplantation

German researchers have used laser forward transmission methods to print living cells. This method provides sufficient resolution and cell density for tissue formation. This technology has proven to make it possible to create three-dimensional cell construction using living cells, thereby eliminating the need for animal testing of chemicals, pharmaceuticals and cosmetics. Ultimately, this method is also expected to create a fully functional organ for use and transplantation.

3, the United States successfully used collagen 3D to print non-living heart and coronary artery

A bioengineering research team at Carnegie Mellon University has developed a new bio-printing technology that uses a printer purchased from a modified store to load soft materials such as collagen and other tissue-engineered gels. Living heart prototype and coronary artery. At this point, the dream of creating custom functional organs for patients is gradually becoming a reality.

4, Blu-ray Inno released the world's first 3D biovascular printer

On October 25th, Sichuan Blu-ray Inno Biotech Co., Ltd., a wholly-owned subsidiary of Blu-ray Development, announced that the National High Technology Research and Development Program (863 Program) has achieved a major breakthrough in the 3D bio-printing vascular project with complete independent intellectual property rights. The world's first 3D biovascular printer came out.

This 3D printer has a compact and precise dual nozzle that prints the basics of life, the blood vessels, with bio-ink on a special space rotating rod. This marks an important step in the development of precision light in the field of precision medicine.

Experts hot discussion on 3D bioprint "road map"

On October 25th, industry experts gathered in Chengdu's 3D bio-printing vascular project major breakthroughs and product launches, and expressed their views on the "3D narration" link, and discussed the 3D bio-printing "road map".

The industry said that the future direction of 3D printing is two key points: The first is the industrial field, with the focus on the development of metal 3D printing technology. The second is in the field of biomedicine. What we see today is only the application stage. For example, bone repair and surgical drills are an auxiliary means. The final direction of bio 3D printing in the future must be organs, cells and soft tissues.

Summary: Bio 3D printing now has a new beginning, but when it can print human organs, I believe that the road ahead is still very long. But we have reason to believe that in the next three to five years, the world's 3D bio-printing industry will usher in an important node. After 10 years, the world's 3D bio-printing technology will rise to a new higher level and basically mature.
