[Scientific power] Innovative innovation!Amazing 3D printing

3D printing (3D Printing) refers to a type of fast molding technology, also known as additive manufacturing. It is a technology based on digital model files, using powder metal or plastic, etc., and constructs objects by printing layer by layer by layer by layer.

3D printing is usually implemented with digital technology material printers. It is often used in the fields of mold manufacturing, industrial design and other fields, and is gradually applied to the direct manufacturing of some products, printing parts through this technology.

In August of this year, "Nature -Communication" published a research article that manufactured flexible electrostatic lighting devices through 3D printing. Liu Ji, an associate professor of the Department of Machinery and Energy Engineering from Southern University of Science and Technology, introduced a kind of manufacturing flexible, extended light -stretched light, The device's 3D printing strategy, which can integrate with software robots. They demonstrated with a software robot that can change colors based on the background, which may be used to develop next -generation smart monitors, wearable electronic devices and artificial disguise systems.

This study reported the method of using multi -material 3D printing technology to manufacture flexible electrostatic lighting devices. The Liu Ji team adopted ionic conductors, electrophoretic glow and insulation ink that can be used for 3D printed, to create a convenient operation and flexible extension of electrostatic lighting device.

They used this method to make a flexible wristband with blue light, and integrated the device into a software robot. The robot can change the surface color to the background like a color transformer. Researchers pointed out that the device still has electrical luminous stability even under different mechanical deformation modes (such as bending, twist, stretching). It can be used for flexible electronic devices and related components of the camouflage system.

Looking back at the development of 3D printing, you can find that 3D printing has long been in jewelry, shoes, industrial design, construction, engineering and construction (AEC), automobiles, aerospace, dental and medical industry, education, geographical information systems, civil engineering and other fields. Application.

The first time of 3D printing was began to be used by people in the mid -1990s. At that time, 3D printing was the latest fast molding device using optical curing and paper layer overlapping technologies. The principle of ordinary printing is basically the same. The printer is equipped with "printing materials" such as liquid or powder. After connecting to the computer, the "printing material" is superimposed through computer control, and the blueprint on the computer is finally turned into physical objects. Due to the effect of the original items, it is called 3D stereo printing technology.

On January 14, 2019, the University of California California used the rapid 3D printing technology to create a spinal stent imitating the central nervous system structure, which successfully helped the rats to restore the movement function. This is the original application of 3D printing.

Medically, people are printed through 3D and obtained the required accessories with corresponding chemical raw materials. This technology is widely used in the medical field of dental medicine.

In November 2012, Scottish scientists used human cells to print artificial liver tissue for the first time with a 3D printer.

On April 15, 2019, researchers at Tel Aviv University in Israel used the patient's own organization as raw materials, and 3D printed the "complete" heart with cells, blood vessels, ventricles and atriums in the world, which is the first case in the world.

In June 2022, according to foreign media reports, a 20 -year -old woman from Mexico became the first person in the world to successfully perform ear transplantation through 3D printing technology.

Nowadays, 3D printing has gradually received people's attention, and the 3D printing laboratory of commercial operations has also emerged. More companies will also print higher quality prototypes through professional 3D printing laboratories.
