In the film above this text is the fastest ship in the world. The ground-effect aircraft can easily be the size of the ship. But it's hard to control, and the needed aviation systems need fuel. So what if we would replace the cargo ships by using automatic factories. The CAD images of the products can send over the internet to the 3D printer factories.
The 3D printers are perfect CAM (Computer-Aided Manufacturing) systems because they are flexible. In those systems, the 3D printers are operating in a vacuum. And that allows those factories to make extremely high accurate metal parts where are no bubbles inside them.
The idea of the world where the objects are sent to the internet for the receiver, where is the 3D printer came into my mind one day when I walked over the post boxes. The idea might seem funny, but why in those mailboxes cannot be the 3D printers, and that allows making the stuff in those boxes. That means the people would send the data of the gift to the printer.
And that will make the tool in the mailbox by using the 3D printer. But can that thing be possible someday? Who knows where the wind blows. What if all of us would have our 3D printer in our mailbox, and when we want something, we just pay the license and the printer will make that product for us.
3D printers can create flawless and high-quality machine parts by using carbon fiber and metals. If those 3D printers operate in a vacuum they can make the parts where are no bubbles. And use laser finalizing tools can make those systems make high-quality parts. The problem with those high-temperature systems is that they can use to make illegal weapon parts.
Technically it's possible to send the 3D CAD images to the remote-control 3D printer over the ocean and that 3D printer will make the physical object by following the drawings and orders. The reason why the 3D-printed metal parts do have not the same quality as the regular way cast products is simple. There is air in the process. If the 3D printer system working in the air, there are air bubbles in the product.
If the air is removed and the system uses the vacuum and laser systems for finishing the layer. The 3D printer can produce metal parts that have at least the same quality as the regularly made metal parts. And this technology is advancing. The Saab aircraft corporation has tested the 3D printed parts for the jet engines. That means the 3D printers must re-estimate. The things like weapon parts can make by using high-temperature 3D printers that are transformed welding machines.
The computer-controlled MIG welding machine which is operating in a perfect vacuum and transformed into the 3D printer might not alone make the very accurate machine parts. But if the system has the laser scanner and the laser-based finishing tool, where the high-accurate laser ray will finish the object the accuracy of the system is extremely high. And that means that this kind of tool must have some kind of control.
But another thing is that if the images of the physical objects are sent to the robot factories that are basing the 3D printing technology through the Internet that will remove at least partially the need for long-range transportation. And that will remove the bills of the cargo. The robot factories are not very big. The size of those fully automatized factories might be like the container.
