When Adam Feinberg tried to figure out how to synthesize human tissue four years ago, his supplies were prosaic: a kitchen blender, some gelatin packets from the supermarket baking aisle, and a $2,000 3D printer.
“I had no external funding when I started, so we did it kind of on the cheap,” said Feinberg, 38, a biomedical engineer who runs a lab at Carnegie Mellon University in Pittsburgh.
