One of our absolute favorites from the Hardware Battlefield just launched on Kickstarter and they are, if you’ll excuse the cliché, crushing it.
The company appeared on our stage at CES 2015 and showed of an early working prototype. Now, however, they’re ready to take orders and start shipping. The printer is essentially a PCB maker. You put in a board, upload a circuit diagram, and the system draws it in conductive ink. You can then solder in the proper components.
