  • 3D bioprinting involves using printers loaded with biocompatible materials to manufacture living or lifelike structures.
  • In a recent paper, a team of engineers from Carnegie Mellon University's College of Engineering developed a new way to 3D bioprint a realistic model of the human heart.
  • The model is flexible and strong enough to be sutured, meaning it could improve the ways surgeons train for cardiac surgeries.

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.
