How, using a 3D printer with artificial intelligence, the Navy will change the rules of the game

The desire to expand the field of application of 3D printing receives support from an unexpected angle: artificial intelligence can control robots and train them to work even better. You can get acquainted with the prices and choose a suitable model in the online store of 3D printers https://vektorus.ru/ .

When operating aircraft, you need a lot of spare parts, especially for those machines that are assigned to aircraft carriers, because they wear out on complex deck landings and under the influence of salt water. Spare parts are not always at hand, but instead of bringing new ones, in the future, ships of the navy will be able to produce everything that is needed right on the spot.

Imagine a laser-controlled intelligent robot that can analyze problems and 3D-print necessary parts from a titanium alloy directly on board a ship from a stockpiled supply of metal dust. This is the future that the Office of Naval Research (OWMI) offers: today they presented a two-year contract worth $ 5.8 million, the purpose of which is to create a new generation of smart 3D printers. They will not only print the details on demand, wherever it is needed, but they will also be able to observe, learn and make decisions independently, according to Lockheed Corporation representatives.

The joint project was launched by the Lockheed Martin military industrial corporation, the Oak Ridge National Laboratory, Carnegie Mellon University, and four other companies. The development team will begin with Ti-6AI-4V, a common titanium alloy used in aerospace systems. If the project succeeds, it will show how artificial intelligence can change everything we know about manufacturing.

Trust cars

It’s easy to imagine how the production of new parts right on the spot will change the situation for the US Navy. But there is a small problem that limits the use of 3D-printed parts in machines subjected to extreme loads, such as spaceships and airplanes.

Think about the materials themselves. Metals for aerospace systems, including several titanium alloys, are manufactured in foundries and have well-known characteristics. This raw material has guaranteed strength, permeability and resistance to temperature. But this is not the case with metal printed on a 3D printer, because it is made in layers.

What engineers call the microstructure of the metal — meaning the size, shape, and position of the particles — cannot be a guaranteed characteristic of a part printed on a 3D printer. It will look the same as that produced in the traditional way, but may exhibit other qualities in operation.

“When using traditional subtractive technology, you always have the same properties of the final part,” says Glenn Adams, a 25-year-old welding veteran who works for Lockheed in Michaud, Los Angeles, “But in additive manufacturing, the material and mechanical properties are not well understood. ”

However, OWMI has a plan. 3D printer manipulators are going to be equipped with special sensors, with the help of which researchers hope to create a database - it will combine the process and conditions of 3D printing with the microstructure of the printed object. Such data will create predictable models that allow 3D printers to produce parts anywhere with the same consistent result as a foundry. “We need to integrate quality into the part,” says Griffith.

It is here that artificial intelligence will play its role. Self-learning algorithms will allow the 3D printer to independently make changes so that the quality of the material matches what the navy needs. Printing takes place remotely: just provide the form and the necessary characteristics of the metal, and the 3D printer will figure it out. In other words, printers will learn how to make their own decisions about how to print.

“We will open the door to orbital production”

“When you can trust a robotic system to make a quality part, the question is who and where can build usable parts,” says Zach Loftus, Lockheed Researcher in the Additive Layering Division.

In the future, the navy or spaceships will be able to learn from each other's experience, transferring data from each robot to a central server. “The OWMI project is at the forefront,” says Griffith. But he works at Lockheed in the space research department, opening up new horizons for the use of parts manufactured on a 3D printer. Smart 3D printers will present new possibilities for building in space, which will help save money on launches and make quality control possible.

“We will open the door to orbital production,” says Griffith. “Think about the freedom that additive manufacturing will offer when we can trust the characteristics of the materials we produce.”
