A route for avoiding defects during additive manufacturing

Laser powder bed fusion is a dominant additive manufacturing technology that has yet to reach its potential. The problem facing industry is that tiny bubbles or pores sometimes form during the printing process, and these ...

Study reveals robust performance in aged detonator explosive

In a large, statistically significant, one-of-a-kind study, researchers at Los Alamos National Laboratory have confirmed that the explosive called PETN (Pentaerythritol tetranitrate), stabilized with a polysaccharide coating, ...

Making (per)waves: Space study could improve future fuels

What looks like an engine made its way to space and back last November. While the hardware of the Perwaves experiment will not end up in your car, results from this research could lead to more efficient and carbon-free fuel ...

Precise magnets 3-D printed from special stainless steel

It looks quite inconspicuous to the casual beholder, hardly like groundbreaking innovation: a small metallic chessboard, four millimeters long on either side. At first glance, it shines like polished steel; at second glance, ...

High color purity 3-D printing

Selective powder sintering for 3-D printing has recently become an increasingly affordable solution for manufacturing made-to-order elements of almost any shape or geometry. This technique involves heating a bed of powder ...

Researchers develop smaller, lighter radiation shielding

Researchers at North Carolina State University have developed a new technique for shielding electronics in military and space exploration technology from ionizing radiation. The new approach is more cost effective than existing ...
