Gold Nanoparticles Detect 3D-Printed Defects

Gold Nanoparticles Detect 3D-Printed Defects
Jul-12-18
Gold nanoparticles could solve a significant manufacturing issue by detecting even minute defects in 3D-printed materials.

The technology, from a team at Vanderbilt University, relies on gold nanoparticles about 100,000 times thinner than a human hair, which are embedded within the printed material. When the completed part is subjected to a UV-Vis spectrophotometer, defects can be detected based on where the absorbance decreases—allowing mistakes to be seen with the naked eye. According to the team, the process is quick and eliminates the need for large sensing systems and multiple sensors placed on the part.
