Turning Old Maps Into 3D Digital Models of Lost Neighborhoods

Imagine strapping on a virtual reality headset and 'walking' through a long-gone neighborhood in your city -- seeing the streets and buildings as they appeared decades ago. That's a very real possibility now that researchers have developed a method to create 3D digital models of historic ...

New 3D-Printing Method Builds Structures With Two Metals

Taking a cue from the structural complexity of trees and bones, engineers have created a way to 3D-print two types of steel in the same circular layer using two welding machines. The resulting bimetallic material proved 33% to 42% stronger than either metal alone, thanks in part to pressure caused ...

High-Tech Pavement Markers Support Autonomous Driving in Tough Conditions, Remote Areas

Engineers are placing low-powered sensors in the reflective raised pavement markers that are already used to help drivers identify lanes. Microchips inside the markers transmit information to passing cars about the road shape to help autonomous ...

PAINTing a Wound-Healing Ink Into Cuts With a 3D-Printing Pen

The body is pretty good at healing itself, though more severe wounds can require bandages or stitches. But researchers have now developed a wound-healing ink that can actively encourage the body to heal by exposing the cut to immune-system vesicles. The ink can be spread into a cut of any shape ...
