Use Your Smartphone To Do 3D Printing
I'm sure there's all sorts of things that could be printed using this new mini 3D printer, called OLO. It's only $100, and it uses the white light of a smartphone to harden a special plastic called 'daylight resin.'
This seems more fun than useful, though I guess you could print out small gifts like keychains and toys. The video shows how the OLO can be used in small businesses and by medical professionals.
Let us know what you'd print with the OLO on Facebook.
