Will human beings be able to use 3D printing to create an entire live human body? These and many other medical breakthroughs in gene editing, artificial intelligence and life enhancement were topics of discussion by some of the leading lights of medical and bio-engineering community on the concluding day of the Knowledge Summit on Wednesday. While most of the topics of the panel discussions projected future possibilities in human health, the stimulating session pushed the boundaries of what seem sci FI topics now and are likely to move from the realm of fiction to fact in the next few decades. Atalla pointed out that 3D printing was at a stage where “critical advances in the field of bio-engineering that took years could now be created in a matter of minutes. It is possible to print cells, molecular proteins using additive printing and very soon we might be able to print implantable organs in 3D.”
