  • 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.

Is your company innovating? A Whole Foods case study.
