IIT Jodhpur develops indigenous metal 3D Printer for aerospace


Researchers at the Indian Institute of Technology (IIT) in Jodhpur have developed a metal 3D printer for the aerospace, defense and engineering industries.

All components of the metal 3D printer, apart from the laser and robotic systems, are designed and manufactured in India, officials said.

According to them, the main goal of the project is to reduce the cost of metal 3D printers and attract a wider range of users.

“Even though metal 3D printing technology started a few years after the launch of resin 3D printing, it has yet to experience the huge growth that the resin 3D industry has achieved, especially in India.

“The high price of the product and the more expensive proprietary metal powders imported from overseas are some of the reasons for the limited growth in the number of metal 3D printers,” said Ravi K.R., Associate Professor, Department of Metallurgy and Materials Science, IIT, Jodhpur.

“The designed printer is suitable for repairing and adding additional materials to existing components. Therefore, it is ideal for printing full-featured parts for a range of industries such as aerospace, defense, automotive, oil and gas, and general engineering. little,” he added.

V. Narayanan, assistant professor in the Department of Physics, who is also a member of the team, said the machine can 3D print parts with metal powders made in India.

“In addition, India’s first state-of-the-art laser optics with variable spot size is available in this machine without sacrificing laser beam uniformity for the laser cladding process and additive manufacturing.

“Our team developed the toolpath planning software and the coaxial nozzle for this machine. It also has in-situ monitoring technologies that constantly monitor melt pool temperature and cladding layer thickness during the additive manufacturing process,” he said.
