3D printing is a rapidly evolving technology that could potentially change the world like the internet did. People are most familiar with 3-D printing due to the controversy surrounding 3D printed firearms. But the technology can be used to produce everything from tiny precision components to houses.
Now gold has a role to play in the evolution of 3D printing technology. Scientists at Vanderbilt University have developed a process using gold nanoparticles to reveal tiny defects in 3D printed parts.
