3D printing technology has become a "new darling" in the field of biomedicine. Bone prints entered clinical trials in many hospitals in China. A biological 3D printer in Hangzhou printed blood vessels, fat and liver tissue in the laboratory. One day in the future, can it print out replacements on demand to replace diseased organs that have been invaded by cancer cells, or are they constantly beating? In the eyes of optimistic researchers, it takes at least 15-20 years.

The idea of ​​3D printing originated in the United States at the end of the 19th century and has been developed since the 1980s. In China, 3D printing research has been around for 20 years. This technology, which can superimpose “printing materials†layer by layer, has become popular in the past two years.
At the World 3D Printing Technology Industry Conference held at the end of May this year, researchers shared 3D printed products, clothing, shoes, jewelry, and even snacks and meat. An engineer in the Netherlands also plans to print a house with a giant 3D printer.
Initially, 3D printing was used in the biomedical field to create medical models, and the bones or organs in the body were printed before surgery for the doctor to communicate with the patient or to develop a surgical plan. Now its finished product has successfully entered the human body.
On August 17, the first affiliated hospital of Xi'an Jiaotong University completed a skull repair operation, and the implants used were printed by 3D printing technology using high molecular biomaterials. The 32-year-old Shaanxi Hanzhong young man Li Wei became the first patient to eat crabs.
