Metal 3D printing highlights several major breakthroughs in aviation applications

On September 3, China held the first military parade to commemorate the 70th anniversary of the victory of the anti-fascist war. With the powerful help of metal 3D printing technology , China’s warplanes soared into the blue sky, and the whole scene was “covering the sky” and was spectacular. This powerful behavior highlights China's comprehensive national strength, and the patriotic feelings of people are full of blood.

In recent years, with the improvement of metal 3D printing technology, a series of breakthroughs have begun to appear in the field of 3D printing and aerospace at home and abroad. Below, Xiao Bian will take everyone to review the recent major achievements in the field of 3D printing and aviation in China and abroad.

First, 3D printing key technology boosts China's fourth generation fighter

On July 16 this year, the National Defense Technology Industry Civil-Popular Integration Development Exhibition was opened in Beijing. The overall reinforcement frame of the aircraft fuselage manufactured by 3D printing technology was unveiled for the first time. This is the largest main bearing force of titanium alloy components in 3D printing manufacturing. . According to the China Aircraft Strength Research Institute, components produced using this technology have been used in China's fourth-generation fighters, and the 3D printing industry will usher in major development opportunities.

The industry believes that high-end 3D printing technology meets the requirements of improving the technological content of the defense industry, not only for fighter manufacturing, but also for the traditional manufacturing methods of a variety of equipment in the aerospace industry. The successful application of 3D printing technology on the fourth generation of fighters will inevitably lead to a spurt of downstream demand in the high-end 3D printing industry.

Second, the Israeli 3D printing drone completed the test

At the recent Tel Nof Air Force Base in Israel, they completed tests on whether 3D printers could be used to make drone parts. Although only a few details and plastic parts were tested, it is obvious that using a 3D printer, electronic components can be integrated very cheaply. In this way, the complete drone can be easily manufactured anywhere, as long as a 3D printer is present.

Third, the Italian 3D printing transport aircraft "rushed to the clouds"

Recently, Alenia Aermacchi, an aerospace company under Italy's largest engineering and aerospace and defense group Finmeccanica, successfully conducted its first flight test on its C-27J battleship. One of the special features of this C-27J tactical transport aircraft is that several of its newly designed winglets are 3D printed.

Fourth, NASA 3D printing turbine space travel further

Exploring the mysteries of space is a dream that mankind has been working hard all the time. Recently, NASA (NASA) tested the 3D printing turbine that will be used in rockets, which reduces the weight of turbines manufactured by other processes by 45%. It is also a saving of time and money.

NASA called the 3D printing turbine "the most complex 3D printed rocket engine component". During the test, the turbine experienced 15 different tests to simulate various problems that may be encountered under actual working conditions. The turbine proved to be the case. Not only is it steadily tested, it also delivers 2,000 horsepower, which is twice the horsepower of the NASCAR engine.

With the "crazy development" of 3D printing, metal 3D printing technology has become a difficult and high-standard development branch in the field of 3D printing, and it has gradually begun to "spread the clouds." Not only in the aviation field, but the entire military field has undergone a trembling change in the world. With the attention and support of the leaders of the State Council on 3D printing technology, various policies have been introduced, and we expect that 3D printing will once again lead the great change in manufacturing!
