The new 3D printers are coin-size systems.

Researchers created a 3D printer that is coin-size. That kind of printer can create things like microchips. But it's possible. Those tiny 3D printers can also work in extremely large-size projects. In simplest models, the 3D printers are positioned on tracks. The 3D printer itself is the tool, that can be part of the modular production systems. 

There are visions of high-temperature metal printers installed on the gantry cranes. That makes those crane printers that can make even ship-size things. The crane that the printer controls can move back and forth and the printer can move horizontally. This kind of thing can turn the crane into a high-temperature 3D printer, that can produce large-size objects. 



The small-size 3D printers can installed on robot wagons or in small quadcopters. The ability to move on the ground and in the air makes those tiny robots create complicated 3D structures. The quadcopters that use 3D printers can print almost everything. The raw material can be metal wires that can be hung from a crane. And that material travels through printers. The printer can be below the crane and the raw material travels through the air. 

The idea is that the 3D printer system navigates using the precisely operating GPS. But it's also possible that there is a laser LED in those robots. The camera on the roof or on the drone that hovers above the working area follows the printers. The system requires 3 or 4 points that it can use the triangular measuring system to the precise location of the printers. 

The fact is this. Those small-size printers can fix damages on layers with very high accuracy. That kind of system can make anything. The raw materials are limited for the 3D-printed merchandise. And the miniature printers can make it possible to create new products and make repairments on the field. The miniature printers that are installed onboard ships can repair their damages.

    The AI-based PCs will replace current PCs quite soon. A Lenovo director says.   Lenovo plans to replace current PCs by using new AI-based systems. The AI-based PC is the tool that makes computing more powerful, more effective, and safer than ever before. The Kernel-based AI that guards computers and identifies the users are tools that are required at this time of modern computing. The problem with this type of advantage is that if those AI-based system's servers are in China, makes the PC an ultimate control tool. Another thing is that the host who controls servers can use data collected from the users to create military AI applications. Computer games help to create AI that can respond to all types of actions. And AI also can create things like hypersonic lifting bodies and command systems for military tools. Also, AI can create new types of dual-use systems that control drone swarms in marketing situations for making dragon images in the skies. But the same systems can contro

Quantum computers and ultra-fast photonic microchips can danger even the most secure communication.

"Quantum computers could pose a major security risk to current communication systems in 12-15 years with their exponentially greater speed and code-breaking ability. (ScitechDaily, Today’s Most-Secure Communications Threatened by Future Quantum Computers) Quantum computers can break entire binary cryptography. And that makes all communication unsecured. That is one of the greatest threats in quantum computing. And this brings the arms race to the quantum age. The quantum computer can create codes that any binary computer can break. But the quantum computer can also break old-fashioned codes. And that makes it an ultimate weapon and sabotage tool.   Quantum computers can change the measurements of the ammunition in factories by changing the system calibration. Or it can delete databases from the opponent's computer systems. This thing can delete all SIM cards from mobile telephones. In peacetime, the hackers that operate using quantum systems can steal the names of the counter-
