Wouldn’t it be great if new organs could be printed out and used in surgical operations to save people’s lives? As it turns out, a group of Carnegie Mellon researchers have managed to do almost precisely this, producing models of a variety of human organs and body parts using a hacked 3D printer bought off the shop shelves. The new research, published in the journal Science Advances, demonstrates that it is possible to replicate the heart through 3D printing.
“3-D printing of various materials has been a common trend in tissue engineering in the last decade, but until now, no one had developed a method for assembling common tissue engineering gels like collagen or fibrin,” said TJ Hinton, a graduate student in biomedical engineering at Carnegie Mellon and lead author of the study, in a statement.
