The USA professor USES 3D printing to print flawless metal parts to monitor the printing process and eliminate defects in real time.
Apr 19, 2018

Rao is an assistant professor of mechanical and material engineering at Lincoln university in Nebraska.His grant was part of the staff's early career development plan, which was $500,000 in five years.It aims to support teachers' teaching strength through excellent research and excellent education.

He is going to study the technology for metal AM manufacturing defects, Rao will develop algorithms, and use the special sensor, can undertake real-time feedback about the quality of the  3D printing unit, in order to automatically detect the possibility of a different type of defect and fix them automatically.

"This is a big data problem," Rao said."You have so many sensors, the trick is how you use all the data you collect to determine the time and place of the error and then correct it when you build it."

The sensor he is using will be connected to a special hybrid 3D printer (the LUMEX extender from Japan), which can be added and subtracted at the same time.Nebraska has just invested in three of these devices and will be installed in the Nebraska manufacturing technology lab or NEAT lab, which is expected to open in May.
