Here’s the Why:
“When you’re 3D-printing a tissue culture on the ground, there’s a tendency for them to collapse in the presence of gravity,” he says. “The tissues require some sort of [temporary, organic] scaffold to hold everything in place, especially with cavities like the chambers of a heart. But you don’t have those effects in a micro-gravity environment, which is why these experiments have been so valuable.”
