Three years later, when we saw Oreo again, we were very surprised that it was as lively as it was, and we could not see the abnormality of the left hind leg.

Today, this lucky puppy is still in good health, and the 3D printed knee bones still function perfectly.
The 6-year-old dog named Oreo was taken off the knee bone (tibia) of his left hind leg three years ago. Oreo, who had removed the kneecap, has become a lame.
Oreo's veterinarian contacted a research and testing organization that primarily serves the medical device market to explore how to create a custom implant for Oreo. Later, in just four days, they completed the entire process from design, analysis, physical testing to 3D printing of a custom implant. “When we are familiar with this technical process, it may take only a day or two to make a similar implant in the future,†said the president of the research laboratory.
Eight weeks after the operation, Oreo walked again normally, and I observed that it occasionally hopped. Now, three years have passed, and when I see Oreo again, I feel a lot of emotions. The rapid development of medical technology has made life a miracle.
Market research firm Gartner has released the top ten information technology hotspots in 2015. In this list: 3D printing is impressive. The outsider who knows a little about 3D printing has such a fuzzy perception through analogy: like a printer in the office can print flat paper of various layouts and colors, give enough templates and materials, through 3D printing technology, three-dimensional The car can also be printed, the house can be printed, and even the organs of the human body can be printed.
In the story of the traditional Chinese mythology god Ma Liang, Ma Liang, a poor child with a magic pen, has the ability to make things come true and to become true. "He drew a bird with a pen, and the bird fluttered his wings and flew into the sky. He sang and sang to him. He drew a fish with a pen, and the fish bent his tail and swam into the water and waved at him. When the 3D printing technology with the basic characteristics of "creation" was born, people tried to cast a vision of "Shen Ma Ma".
Can 3D printing deduct the true magic pen Ma Liang? The miracles we are eager to see in Oreo are summoned and ready at hand. The 3D printing technology that plays the hand of God says that there must be a left hind leg, so there is a left hind leg.
But the realization of these good wishes does take some time, especially the biomedical 3D printing technology that is closely related to the human body.
3D bioprinting technology requires human cells as bio-ink. First, researchers will extract stem cells from people's bone marrow or fat and biochemically differentiate them into other types of cells. Subsequently, these cells will be stored as "toner", and each drop of "toner" may contain 10,000 to 30,000 cells. When the 3D bio-printer is activated, the "toner" will be gathered by the print head on the pre-designed part, and the embryo of the printing organ will gradually appear.
"In fact, cell printing is not 'mysterious', but it is necessary to print out living organs, that is, to make the printed cell structure biologically capable, and to overcome many difficulties," said Lin Feng, deputy director of the Biological Manufacturing Center of Tsinghua University.
According to reports, at present, the class organizations printed at home and abroad only have similar structures, but they do not have the functions of organizations. Even for organizations that seem simple, manual reengineering faces enormous challenges. For example, the skin is a very thin layer, but it has many functions. In addition to the protective function, it also has the functions of feeling, temperature regulation and sweating.
Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.
