The 3D printer technology is used to make fully working electric jet engines.

The new uses for 3D printing technology are jet engines and aircraft parts. The thing that makes material sometimes weak in 3D printing is that the air is making bubbles in structure. Metal-based 3D printing is a similar thing to other metal castings. In that process, the system operators must avoid oxygen slips in the 3D printing. Normally air is the thing that makes bubbles and oxides in the layer.

So that's why the 3D printer should operate in the vacuum chamber that is removing the air from the system and denies oxidation. When the 3D printer is making merchandise. that system is making things by welding them layer by layer. So the product looks like a croissant that is made by using metals or carbon fiber.

The problem is that when the gasses like air or oxygen slips between those layers it causes bubbles and oxidation. That slag material is making the discontinuity in the merchandise. And this is the reason why the gas must remove around the working area. The metal-based 3D printer is a modified MIG welding machine. There is also possible to connect the laser system to that 3D printing system. The laser measures the dimensions of the parts. And the laser can also be used for finishing those parts.

The developing technology allows for the creation of more qualified machines and machine parts. 3D printer technology can use to make car engines, like bocks and pistons, other machine parts, turbines, and even cannons for military use. The only thing that limits the system is the operating temperature. The high-temperature systems can make the system operate with stronger metals like steel, titanium, and chrome.

The 3D printer technology is developed in NASA and other space agencies. That kind of system is more flexible than carrying some spare parts with them. The 3D printer systems can also use to fix holes in the body of spacecraft. So they are extremely powerful systems in space and other technical industries.

The metal-based 3D printing technology allows making the gun parts and guns. The 3D printer systems are also used to make parts for high-stress points in super- and hypersonic aircraft. The 3D printer systems can combine with CAD programs. And they can turn to ultimate CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing).

MIT's tractor beam can make the new types of SASER systems possible

"This chip-based "tractor-beam," which uses an intensely focused beam of light to capture and manipulate biological particles without damaging the cells, could help biologists study the mechanisms of diseases."(Interesting Engineering, MIT’s Star Wars-inspired ‘tractor beam’ uses light to capture, manipulate cells) MIT's tractor beam can make the new types of SASER systems possible. The tractor beam just hovers the nanoparticle in air or medium, and then the laser or some other electromagnetic system transports oscillation into those particles. The ability to make cells and other particles hover in the system makes it possible to create particles whose energy level or resonance frequencies are accurately calculated things. That thing makes it possible to create things that transmit wave movement accurately and cleanly. This is one version of the use of a tractor beam. Modern tractor beams are like acoustic tweezers where sound waves lock the object in its cr

The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible.

That could make gamma-ray lasers possible. The process has been observed by the NASA (Lockheed) ER-2 research plane, which is a modified U-2 spy plane. The gamma-ray formation in thunderstorms. Where lightning and electric fields release electrons that impact the air molecules and water droplets is an interesting thing. That thing opens the route to solving many mysteries. "The general physics behind how thunderstorms create high-energy flashes of gamma radiation is not a mystery. As thunderstorms develop, swirling drafts drive water droplets, hail, and ice into a mixture that creates an electric charge much like rubbing a balloon on your shirt. Pos

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft. Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things. In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion. If we th
