In the 80s, when the first 3D printers appeared, no one thought that 30 years later they would so drastically change the industrial way of the planet, and possibly the appearance of the entire world economy.
While for most people, the concept of 3D printing is associated with the production of various plastic trinkets, but in fact, complex products made of wood, metal and fabrics are already available to it. The US military-industrial complex is showing great interest in the new technology, where, in particular, unique developments are underway to create artificial leather for the wounded and even food.
Massachusetts Institute of Technology has already developed 4D printing technology, which opens up the possibility of creating materials that change upon contact with water. Chameleon materials may appear soon, changing color depending on the setting. At the end of last year, the British company BAE Sistems first printed a part for the Tornado fighter.
However, the rapid development of 3D technologies can turn into serious problems for the military industry. The fact is that the army itself will be able to produce, for example, the necessary spare parts for military equipment, which can literally bury entire branches of the defense industry.
3D printing can affect foreign policy as well. Now a country where these technologies are well developed will not be afraid of any sanctions associated with the embargo on the supply of certain types of industrial products.
