3D printers are available for purchase right now. I suspect the price will come down, too.
What can you do with a 3D printer?
Here's an example:
http://mjperry.blogspot.com.au/2012/...ted-magic.htmlTwo-year-old Emma was born with a rare disease called arthrogryposis that makes it so she can’t raise her arms without assistance. Through the use of 3D printing, a Delaware hospital created a mobile plastic exoskeleton that now allows Emma to use her arms for many things.
3D printing ensures that a new exoskeleton can be created if Emma breaks or outgrows it. Emma is now on her second 3D-printed jacket and calls the device her “magic arms.”
