Nobel Laureate in Chemistry Daniel Shetman: 3D printing will become a rolling technology|

Israeli materials chemist Daniel Shetman won the 2011 Nobel Prize in Chemistry for his discovery of a new class of materials called quasicrystals.

Recently, Daniel Shetman said in an interview with the media that although 3D printing is not a new technology, there will be a larger market in the future. At the same time, as a scientist who discovered new substances and experienced opposition, he shared one of the most "hard-core" methods of opposition - becoming an expert in his field.
Competition is driving innovation in 3D printing

When it comes to the topic of 3D printing technology, Daniel is very excited. The nearly 80-year-old Nobel Laureate in Chemistry told reporters that 3D printing technology is not a new technology in nature, but from his point of view, 3D printing technology will have a larger market, and its development prospects will be brighter. Surprisingly.

"I think 3D printing can now become the most developed and leading technological capability in the world." Daniel said that 3D printing is currently only applied to a very small part of people's lives, and in the future, this technology can be used to print Larger products and equipment such as bombs, houses, etc. In addition, 3D printing technology can also work on very precise and delicate products, such as photographic equipment and human organs.

"So I think that in the future, 3D printing will become a rolling technology, and its development will be very rapid. Why is it developing rapidly? Because it has huge competition, and competition can drive innovation." Daniel said .

Quasicrystals, discovered by Daniel Shetman, also sparked a spark with 3D printing. According to Daniel, the latest area of ​​application for quasicrystals, their additive manufacturing capabilities, can be applied to 3D printing.

"We know that 3D printing can now print many plastic products, metal products, and even some ceramic products. Through this property of quasicrystal, it can generate a kind of infrared, which can melt plastic powder and connect another materials and fuse them together to generate a new kind of infrared light," Daniel said.

The best way to resist questioning is to become a domain expert

In addition to applications in 3D printing, quasicrystals are now also being studied by scientists in various fields, trying to apply them in non-stick pans and light-emitting diodes.

This quasicrystal, discovered in 1982, has fundamentally changed the way chemists view solid matter.

Prior to this, the academic community generally believed that atoms were distributed in a symmetrical pattern in a crystal, but Daniel's discovery of quasicrystals revealed that the stacking of atoms in a crystal may not be repeated.

Daniel's surprising discovery caused a lot of controversy at the time. He himself was even publicly questioned by Linus Pauling, who won two Nobel Prizes: "There are no quasi-crystals in the world, only quasi-scientists." In addition, Daniel was also asked to leave the original research group. However, he stayed true to his point, and in the end, the discovery led scientists to re-examine their ideas about the nature of matter.

After a lapse of decades, when Daniel recalled this past event again, he told reporters that if he wanted to resist these objections, especially when there was a very great chemist among them, the most important thing was The best way is to become an expert in your field. "I am very professional in my field, so for me, it was very easy and able to maintain my discovery." Daniel said.

For young people who want to become scientists, Daniel also suggested that in order to succeed in scientific careers, they need to have rich and broad knowledge. Also, young people should be the top talent in their field so that they can achieve what they want.

In addition, Daniel Shetman said that for the greatest scientists, the greatest reward is not a Nobel Prize, but the joy they find in their daily work and their own sense of accomplishment. Feeling this joy can help scientists better explore the unknown in the world.
