A popular research firm has forecasted a 10.0% of the people living in the developed world to have 3D-printed items in or on their bodies by 2019. Furthermore, over a third of surgical procedures incorporating the use of implanted devices and prosthetics could involve 3D printing as a central tool. Another research company has estimated the 3D printing market to grow from a US$0.66 bn in 2016 to a US$1.21 bn by 2020. 3D printing in healthcare has been prognosticated to bear a transformative impact of the cloud or the World Wide Web. Besides organ models, 3D printers could be engaged in healthcare to produce human skin, drugs, prosthetics, hearing aids, and medical and dental implants.
