'Printer' Creates Organs for Transplant Use of new technique could eventually end waiting lists for organs By John Johnson, Newser Staff Suggested by Disillusioned Posted Jun 4, 2010 10:51 AM CDT 8 comments Comments A file photo of surgeons. (Photo: Business Wire) (Newser) – The principles of 3D printing are being applied to medicine, raising the possibility that doctors might someday be able to produce human organs for transplant and end the use of waiting lists. California biotech company Organovo already has a prototype of the so-called "bioprinter," which uses two printer heads to place cells ("bioink") onto a water-based gel ("biopaper"). For more details on the process, see the Telegraph and, especially, the Engineer. “Ultimately the idea would be for surgeons to have tissue on demand for various uses," says Organovo's chief executive.
