Russia began using industrial 3D printers to create prototype components and master models for its third-generation T-14 main battle tank (MBT) in 2015, a Russian 3D printing specialist, whose firm executed multiple projects with Indian defence firms, including BrahMos missiles, told Sputnik India.
As far as India is concerned, aviation major Hindustan Aeronautics Limited (HAL) and tech company Wipro 3D signed an agreement to collaborate on designing, developing, manufacturing, and repairing aerospace components using metal 3D printing a couple of years ago.
The India-Russia 3D printing partnership is focused on creating and certifying aerospace parts, including maintenance, repair, and overhaul (MRO) components, ensuring their reliability through rigorous testing, the expert highlighted.
"I believe this is a great opportunity for the industry, especially in defence and MRO sectors, where 3D printing could greatly enhance the production of parts for military platforms like fighter jets and transport aircraft," he added.
"India is increasing its missile arsenal significantly, and 3D printing will ensure bulk production of the missiles in a very short time frame, thus obviating the need to have a physical stockpile for a long duration which – apart from being hazardous – also requires regular maintenance when stored for long durations," Sodhi stated.
Traditionally, these motors are made from special steel alloys using extrusion methods, he remarked.
"Although production of these projectiles is underway, the current capacity may fall short of meeting the demands during wartime. At full production, only around 2,000 units could be produced each year, a number that could be used up in just two months of heavy fighting," Linganna observed.
3D printing can greatly speed up the production of essential missile parts, helping to quickly restock supplies during a war, Linganna asserted. Its flexibility also allows for the creation of new and innovative missile designs with complex shapes, which could improve performance.
"Additionally, India's Military Engineering Services (MES) have used 3D rapid construction technology from private companies to build two houses at the South-Western Air Command in Gandhinagar and Jaisalmer. However, the military's use of 3D printing goes beyond just housing. They are now being asked to construct bunkers and vehicle parking facilities in border areas where traditional building methods are difficult due to harsh weather, limited labor, and threats from neighboring countries," he concluded.
