Buried "megaripples" — some the size of five-story buildings — are helping scientists piece together the devastation following the impact that wiped out the nonavian dinosaurs.

A video demonstration of the process shows a 3D-printing machine globing on layers of hydrogel skin substitute onto a square surface.

Penn Engineering materials scientist Shu Yang and Weitzman School of Design architect Masoud Akbarzadeh teamed up to develop a 3D concrete printing system that captures carbon dioxide and boosts the ...

Non-destructive tests on the tires included an assessment of static friction by measuring the torque needed to start the tire rolling against a rough surface, plus a dynamic friction test using ...

Unveiled in May, the column-wrapped tower is officially the tallest 3D-printed building in the world. It won’t house any residents, but it will lure visitors to the town, something that’s ...

UPenn engineers reimagine concrete 3D printing with algae. The concrete ink is based on diatomaceous earth that has enhanced ...

By 3D the coral-like materials, surgeons can quickly have access to an on-demand supply of grafting material. This coral-like 3D-printed grafting material was implanted on the tibias of test mice.

A 3D-printed toilet is so slippery that almost nothing can stick to it, even after heavy use, meaning it could massively reduce the amount of water used for flushing. There are many kinds of ...

Queen guitarist and astrophysicist Brian May is about to release a book of 3D photographs of the near-Earth asteroid Bennu, based on images gathered by NASA's OSIRIS-Rex spacecraft.

A near-Earth asteroid named Bennu has a loosely packed surface similar to a pit of plastic balls, according to NASA scientists. A spacecraft collected a sample from the asteroid in October 2020 ...

A 3D printing company working with NASA is hoping to build infrastructure on the moon. Closer to home, Icon is 3D printing the first large community of 3D-printed houses.
