The brain is one of our most vulnerable organs, as soft as the softest tofu. Brain implants, on the other hand, are typically made from metal and other rigid materials that over time can cause inflammation and the buildup of scar tissue.

It takes an average of 7.5 months to build a new home. Even the smallest of domiciles — cabins, micro homes — usually take months to construct. But the Ukrainian startup PassivDom has cut that time down to as few as 8 hours by using a 3D-printing robot to print autonomous, mobile homes for $64,000 each.

Ultrafast Holographic Printer Creates 3D Objects in Mere Seconds

Rather than one layer at a time, this method creates an entire object all at once, using lasers.

Imagine this, you see something online you just have to have, like a rugged smartphone case emblazoned with your favorite character. You order it and instead of waiting for it to be delivered, your 3D printer fashions it for you, to your exact specifications, in seconds. Why don’t we have this right now? 3D printers can take hours or even days to create an object, making such a scenario difficult to implement.
