Gold Nanoparticles Illuminate Defects in 3D Printed Objects

Defects in 3D printed parts can cause all sorts of problems, but they’re often so small that they can’t be easily detected, if at all. Vanderbilt University researchers are the…

Reducing High Porosity and Improving Sealing Properties in Extrusion-Based 3D Printing

While there’s been a lot of ongoing research into what causes structural defects (porosity) and other flaws in metal 3D printed parts, let’s not forget that 3D printed objects made with…

Powerful X-Rays Put to Use in Study of Physics Behind Metal 3D Printing Process as Researchers Seek to Eliminate Structural Defects

From medical tools and aerospace turbines to components for race cars and satellites, it may seem like metal 3D printing can be used to magically make just about anything, for less…
