Re: Absolutely Amazing!
@David, I remember watching a documentary in which scientists were creating a human ear in a lab dish. Their major difficulty was to get the cells to create the soft bone structure of the ear -- 3D printing just made that documentary obsolete.
I hope scanning technology is also progressing at an equal pace, because consumers will require a technology that can capture 3D shapes.
I have heard of spectroscopy scanners that have become so small that the device can fit in a user's hand (powered by the cloud in the background), the device can report data down to the molecular level to the user. For instance, if a user scans sugar then, the device will display C12H22O11.
