Stargaser writes "Scientists at Wake Forest Institute of Regenerative Medicine are using inkjet printers to create organs and tissues, that's something that could change the very way of studying tissue engineering. Regular ink cartridges available almost everywhere are emptied, cleaned and filled with the cells needed to create the organ. Then, an inkjet printer prints these cells into a substance resembling human tissues. Printed layer by layer, cells form the required shape of muscle or organ. Adopting inkjet printers for the need of tissue engineering resulted in more precise, accurate, fast and, most importantly, controlled creation of biomaterials. It seems to me that inkjet technology for today's science is like an invention of the wheel for our ancestors — it's spread far over the area it was designed for."
