What kind of help does 3D printing help in the military industry in various countries?

The old saying goes: "There is no accumulation of steps, no more than a thousand miles; no accumulation of small streams, no rivers and seas." The road of a thousand miles needs to step out, the emphasis here is the importance of accumulation. Speaking of accumulation, here is a technology that comes to mind: 3D printing. This is a special technology. Unlike the traditional “material manufacturing”, it is an “additive manufacturing” method, which is to superimpose materials layer by layer, from the bottom layer to the upper layer, so that layer by layer manufacturing, layer by layer Additives will slowly become a finished product of 3D printing.

To maintain the aircraft and improve the combat effectiveness of the aircraft, the US Air Force and OC-ALC are now developing a strategic plan to incorporate 3D printing technology into their current airpower and maintain every aspect of the mission. OC-ALC wants to optimize its workflow with 3D printing technology, including additive manufacturing aircraft engine components and 3D printing of modern electronic components designed by the 76th Software Maintenance Group.

In fact, OC-ALC's plan is only one of the similar plans being developed by several US Air Force logistics complexes. In addition, the United States also has Robins Air Force Base in Georgia and Hill Air Force Base in Utah. Each base will develop a program for the complex that incorporates 3D printing technology into its aircraft maintenance and development capabilities. The inclusion of additive manufacturing technology will have a huge impact on logistics operations and will greatly enhance the ability of the entire military base to maintain aircraft.

● UK: 3D printing "Cyclone" fighter parts

In January 2014, a "Gale" (or "Cyclone") fighter aircraft using parts produced by 3D printing technology completed the test flight and was considered by the British media to be a landmark event for large-scale use of 3D printing technology in the aviation manufacturing industry. . British Aerospace Systems pointed out that the 3D printing components of the aircraft that successfully tested the flight included the cockpit radio shield, the landing gear guard and the air intake bracket. These components were all produced and assembled at a military base at the Royal Air Force, which the company said was the first flight test of a fighter equipped with 3D printed components.

The cost of manufacturing these 3D printed parts is very low, some even below £100 (£1 for $1.64). In terms of repairing and replacing parts, 3D printing technology is expected to save the Royal Air Force £1.2 million over the next four years. In addition, 3D printing technology makes these parts no longer restricted. If these 3D printers are sent to the front line, direct processing and repair of parts will greatly enhance the capabilities of the British Air Force.

Speaking of South Korea, this country, which is hardly valued in the military, also makes a difference in 3D printing. In June of this year, the F-15K fighter engine used by the Korean Air Force was damaged. The titanium alloy turbine shroud and cobalt alloy air seal on the engine needed to be repaired. They wanted to find a durable and reliable method. Parts are upgraded without sacrificing any quality.

DMT technology to repair F-15K fighter parts

What kind of help does 3D printing help in the military industry in various countries?
The working principle of DMT technology is mainly to melt metal powder with high power laser.

In this repair, the Korean Air Force chose to use 3D printing technology, so they found that German 3D printer manufacturers quickly completed the repair of engine shrouds and seals using specialized DMT technology. The working principle of DMT technology is mainly to melt metal powder with high-power laser. It is considered as one of the latest and most promising 3D printing technologies, and it can repair the parts of Korean military aircraft almost immediately.

During the operation, the metal powder is continuously fed into the 3D printer, and is uniformly melted by the laser, and then re-cooled to a solid. The DMT technology ensures that there is no leakage failure, and the 3D printing parts can also provide excellent mechanical properties. Therefore, 3D Print will keep the main fighter F-15K in Korea at its best, and you can have enough confidence to face an intimidating opponent like North Korea.

As we all know, logistical replenishment is the weakest link on the battlefield. During the Afghan war, the US military used a large number of combat forces to ensure the smooth supply of supplies and ensure the safety of personnel. The US military believes that if 3D printers and battlefield networks are used at the time, no one By combining a transport helicopter or a car, this problem can be completely solved, and 3D printing technology can be used to create a revolutionary change in the logistics support that can meet the actual needs of food, medicine and equipment.

It can be seen that as long as the technology is mature enough, everything needed in the future battlefield, 3D printing can almost be satisfied. With this "clone" logistical "mobile arsenal", wartime can quickly supplement combat consumption.
