3D printing once again ushered in a breakthrough. Tel Aviv University researchers "printed" the world's first 3D vascularized heart using the patient's own paper and biomaterials, and published the research in "Advanced Science" Results.
So far, 3D printing has ushered in a major breakthrough. After imitating the spinal cord scaffold that produced the central nervous system results, it has successfully printed important organs of the human body. Perhaps in the near future, 3D printing can gradually be used for civilian purposes and become an indispensable part of our lives.
So what is 3D printing technology? It is similar to the printing technology we usually see. It is a technology that uses adhesive materials to construct objects by printing layer by layer based on digital model files. The range of materials that can be bonded is very wide, including but limited to plastics, some metals, some food materials, etc. By connecting to the computer and using computer control to stack the printing materials layer by layer, the digital model files on the computer are finally turned into physical objects. Since most of the materials used in 3D printing at this stage are linear, the printing method is similar to the loom weaving method, and the printed finished product feels very close to the finished garment. That’s why some people also call 3D printers “advanced looms”.
At the same time, due to the wide range of optional materials for 3D printing, the use scenarios of 3D printers are also very wide. So far, 3D printers have been used in many fields such as the electronics industry, medicine, aerospace technology, and housing construction, helping people research more cutting-edge content and improve their lives.
Currently, 3D food printing is very popular around the world. More than 20 countries and regions including Spain, the United Kingdom, and the Netherlands have relatively successful commercial cases. This field in my country is still an emerging industry, and the main sales targets are hotels. For commercial enterprises such as shopping malls and restaurants, direct-to-consumer scenarios are relatively rare, which is a blue ocean market that can be developed.
However, there are also some problems with the popularity of 3D printers. Although the geometry and techniques for reconstructing objects have now reached a certain level, almost any static shape can be printed, but dynamic objects and their clarity are more difficult to achieve.
In addition, depending on the printing material, the size of the printer will also change. At the same time, according to an unnamed person, the printing efficiency of 3D printers is a huge difficulty. At this stage, it takes about 30 minutes to print a small and simple plastic toy. Printing a simple metal product requires the machine to work continuously for 1 to 2 days. How to improve the printing efficiency of 3D printers will become a difficult problem that manufacturers need to overcome.
