Additive Manufacturing put to the test by new $1.5M X-ray CT system at Auburn University

The Center for Additive Manufacturing at Auburn University, Alabama, is now home to a $1.5 million x-ray CT system. The new machine is to be applied to the nondestructive testing (NDT) of 3D printed parts, essential to the university’s programs to produce “mission critical” parts for aerospace and aviation industries.

The system was acquired with a grant from the National Institute of Standards and Technology (NIST). Professor Bart Prorok, Director of Auburn’s Analytical Microscopy Center, is principal investigator on the NIST grant, and has called the x-ray CT system “a real game changer” for the center’s additive manufacturing research.

“With this new system,” Professor Prorok explains, “we can take two-dimensional x-ray pictures of a metal structure for real-time process monitoring or a series of 2D images in 360 degrees of rotation that are then reconstructed into a 3D representation of the build.”
