Faces - A face is a flat surface on a 3D shape. For example a cube has 6 faces. Edges - An edge is where two faces meet. For example a cube has 12 edges. Vertices - A vertex is a corner where ...

Mathematicians have identified a new class of shapes that "tile space without using sharp corners." From bathroom floors to ...

Researchers have created microscale robots less than 1 millimeter in size that are printed as a 2D hexagonal 'metasheet' but, with a jolt of electricity, morph into preprogrammed 3D shapes and crawl.

The researchers matched the 3D shapes to the structures of proteins whose functions are already known. Because the structure of a protein directly contributes to its biological function ...

We have used a 3D nanoprinting technique to produce one of the most promising shapes known – Archimedean truncated tetrahedrons. They are micron-scale tetrahedrons with the tips lopped off. Wendy Gu, ...

More affordable than ever, 3D printers are booming for personal, professional, and educational use. Here's everything to know before you buy one, along with the top models from our hands-on testing.

Today's affordable 3D printers will likely surprise you: You can get a smooth-working machine with useful features once found only in high-end models. Starting at just $250, these are the top ...

While his main areas of expertise are maker tools -- 3D printers, vinyl cutters, paper printers, and laser cutters -- he also loves to play board games and tabletop RPGs. Expertise 3D printers ...

Still, just as different combinations of building blocks can be used to construct very similar structures, proteins with different sequences may share 3D shapes and play similar biological roles.

The legacy of microscale robotics at Cornell continues to unfold – and refold and unfold itself again. The latest addition is a robot less than 1 millimeter in size that is printed as a 2D ...
