Pretty crazy, we are now able to easily and cheaply print out circuits using silver nanoink on resin paper (PET), in a way similar to how inkjet printers works. In facts inkjet printers can be used in a DIY environment. The time it takes to print is about a minute, and the equipment, no more that $300. Pretty impressive, huh?
