3D-printed paste could hold buildings together amid natural disasters

A 3D-printed cement paste could one day be used to make buildings more resilient to natural disasters, claim researchers from Purdue University. Although it sounds paradoxical, the paste actually gets tougher the more it cracks. This makes it a potentially invaluable new building material. “Cement-based materials such as concrete are brittle and crack as they […]






 
These 3D printed objects can connect to WiFi through plastic, without batteries or electronics

Researchers from the University of Washington have developed 3D-printed plastic objects that can connect to the internet without any electronics or batteries in the object itself. The researchers, who detailed their work in this paper, found a way to 3D-print plastic objects that can absorb or reflect ambient WiFi signals and send data wirelessly to […]
