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).

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

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful. Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down. The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts. The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
