DIY'ers are losing their shit over these printable transistors. Why? Because they could make it that much easier to prototype intricate gadgets without having to send orders to a fabrication plant to have these components made.
The process for making these transistors was designed by Mr Kim and John Sarik who used a Makerbot printer and ink made from silver (along with a few other, not-so-simple steps) to turn theory into reality. What this means for mad scientist who runs their R&D lab out of a garage is that production costs will go down, and prototypes can be built quicker. The full rundown on how these transistors were made can be found here. [Mr.Kim Robotics via Thingiverse]
