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 locally for aerospace, defense and general engineering applications.

According to officials, all components of metal 3D printer are designed and manufactured in India except for laser and robot systems.

He said the main objective of the project was to reduce the cost of metal 3D printers and attract a wider range of users.

“Despite the fact that metallic 3D printing technology started a few years after the launch of polymer 3D printing, the polymer 3D industry has yet to experience the tremendous growth achieved, especially in India.

“The high cost of the product and the expensive proprietary metal powders imported from abroad are some of the reasons for the limited growth of metal 3D printers,” said Ravi KR, co-professor of metallurgical and materials engineering at IIT, Jodhpur.

“The developed printer is suitable for repairs and to add additional materials to existing components. Therefore, it is appropriate to print fully functional parts of a range of industries such as aerospace, defense, automotive, oil and gas, and general engineering. Some,” he added.

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

“Moreover, the machine is available in India’s first state-of-the-art Variable Spot Size Laser Optics without compromising on laser beam homogeneity for laser cladding and additive manufacturing process.

“Our team has developed this machine toolpath planning software and coaxial nozzle with in-situ monitoring technologies that continuously monitor the melting pool temperature and coating thickness during the coupler manufacturing process,” he said.
