How 3D technology is capturing the world
Oct 2019, BBC News
Photogrammetry - making 3-D models out of laser-photographs by simultaneously capturing visual and spatial information. Think of LIDAR, the sonar-like laser beams shooting from the Google maps car in all directions to create a 3-D model.
They're getting good at this, to the point that physical inspections are being done on the models and not the real thing. Which makes sense, what if you want to inspect a bridge for cracks, but it's spanning the Hudson River. You can now make a model of it, and inspect the model instead, and at any scale.
Imagine recreating via 3D printer a scaled version of something that needs to be inspected. Enemy territory, home interior, or just a bit of infrastructure that needs to be inspected for safety. Anything you want to look at, investigate, explore, or immerse yourself in, can be scanned and recreated either in 3D or in virtual reality.
Even other people's bodies? Are we going on tours of people's digestive systems? Somebody brings "back to life" Elvis's colon, models it in 3-D, and prints it out so we can walk through it like a museum?

Living skin can now be 3-D-printed with blood vessels included

In this paper, the researchers show that if they add key elements—including human endothelial cells, which line the inside of blood vessels, and human pericyte cells, which wrap around the endothelial cells—with animal collagen and other structural cells typically found in a skin graft, the cells start communicating and forming a biologically relevant vascular structure within the span of a few weeks.
They're taking two kinds of blood vessel cells, adding them to animal collagen, and printing them onto a substrate.
Within weeks, the cells start working with each other, and spontaneously generating blood vessels.
