Bone-Inspired Architectured Materials

What do bones and 3D-printed buildings have in common? They both have columns and beams on the inside that determine how long they last.

Now, the discovery of how a “beam” in human bone material handles a lifetime’s worth of wear and tear could translate to the development of 3D-printed lightweight materials that last long enough for more practical use in buildings, aircraft and other structures.

A team of researchers at Cornell University, Purdue University and Case Western University found that when they mimicked this beam and made it about 30% thicker, an artificial material could last up to 100 times longer.
