One of the most incredible and quickly-growing sectors of the 3D printing industry is bioprinting. By using inks embedded with cells, researchers are able to print living tissue and biocompatible implants. In the not-too-distant future, it's likely that the first fully functional human organ will be printed in a lab. Australia's University of Wollongong is one of the leaders in bioprinting research, and they are offering a free online course in the subject, in conjunction with online learning platform FutureLearn.
