Quasicrystals, once considered impossible, were found in a 3D-printed aluminum alloy – and they make it stronger. This could ...

A 2D shape could have line symmetry or rotation symmetry, or both! 3D shapes are described by their faces, edges and vertices. The faces can be the same shape or different, and a 3D shape could ...

In 2017, a team at HRL Laboratories, based in California, and UC Santa Barbara discovered a high-strength aluminum alloy that could be 3D printed. They found that adding zirconium to the aluminum ...

The quasicrystals found in this study form the corners of 20-sided shape called an icosahedron. To prove that he found an icosahedron, Andrew Iams had ...
