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).

The LK-99 could be a fundamental advance even if it cannot reach superconductivity in 400K.

The next step in superconducting research is that LK-99 was not superconducting at room temperature. Or was it? The thing is that there is needed more research about that material. And even if it couldn't reach superconductivity in 400K that doesn't mean that material is not fundamental. And if LK-99 can maintain its superconductivity in 400K that means a fundamental breakthrough in superconducting technology.  The LK-99 can be hype or it can be the real thing. The thing is, anyway, that high-voltage cables and our electric networks are not turning superconducting before next summer. But if we can change the electric network to superconducting by using some reasonable material. That thing can be the next step in the environment. Superconductors decrease the need to produce electricity. But today cooling systems that need lots of energy are the thing that turn superconductors that need low temperatures non-practical for everyday use.  When the project begins there is lots of ent

Black holes, the speed of light, and gravitational background are things that are connecting the universe.

 Black holes, the speed of light, and gravitational background are things that are connecting the universe.  Black holes and gravitational waves: is black hole's singularity at so high energy level that energy travels in one direction in the form of a gravitational wave.  We normally say that black holes do not send radiation. And we are wrong. Black holes send gravitational waves. Gravitational waves are wave movement or radiation. And that means the black holes are bright gravitational objects.  If we can use water to illustrate the gravitational interaction we can say that gravitational waves push the surface tension out from the gravitational center. Then the other quantum fields push particles or objects into a black hole. The gravitational waves push energy out from the objects. And then the energy or quantum fields behind that object push them into the gravitational center.  The elementary particles are quantum fields or whisk-looking structures. If the gravitational wave is

The CEO of Open AI, Sam Altman said that AI development requires a similar organization as IAEA.

We know that there are many risks in AI development. And there must be something that puts people realize that these kinds of things are not jokes. The problem is how to take control of the AI development. If we think about international contracts regarding AI development. We must realize that there is a possibility that the contract that should limit AI development turns into another version of the Nuclear Non-Proliferation Treaty. That treaty didn't ever deny the escalation of nuclear weapons. And there is a big possibility that the AI-limitation contracts follow the route of the Nuclear Non-Proliferation Treaty.  The biggest problem with AI development is the new platforms that can run every complicated and effective code. That means the quantum computer-based neural networks can turn themselves more intelligent than humans. The AI has the ultimate ability to learn new things. And if it runs on the quantum-hybrid system that switches its state between binary and quantum states,
