MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051049 A) filed by Cvr College Of Engineering, Hyderabad, Telangana, on April 22, for 'adaptive energy density control system for metal additive manufacturing.'
Inventor(s) include Lava Kumar Polisetty.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "For the purpose of improving build quality and reliability, the present invention pertains to a system for adaptive control of energy density for metal-based Additive Manufacturing (AM) processes, particularly LPBF. To ensure constant monitoring of thermal behavior and melt pool dynamics during the build process, the system employs in situ sensors such as IR cameras, and photodiodes. So as to ensure energy density remains in its ideal value, the gathered data goes through processing using a closed loop control algorithm which modifies factors like the laser power, scan speed etc. The benefit of using this technique is that it allows for compensation of geometric complexity, thermal and powder-related issues. The process results in better mechanical performance and surface finish while minimizing defects like porosity. The system is applicable as a retrofitted module and offers data logging capability, hence making it suitable for industrial AM processes demanding high-quality metallic parts."
