3D printer produces 'heart on a chip'

You may love your computer or your phone, but can a bunch of circuits and wires really love you back? Well, probably not—but Harvard University researchers have used 3D printing to produce a heart on a computer chip.

The organs printed on chips, also known as microphysiological systems, can simulate the structure and function of native tissues, carrying the potential to be alternatives to animal testing. The printed hearts can be printed and customized so researchers can collect data for short- and long-term studies.

"We are pushing the boundaries of 3D printing by developing and integrating multiple functional materials within printed devices," Jennifer Lewis, Hansjorg Wyss Professor of Biologically Inspired Engineering and coauthor of the study, said in a news release. "This study is a powerful demonstration of how our platform can be used to create fully functional, instrumented chips for drug screening and disease modeling."
