You’re playing a game on an obscure old gaming system when the controller breaks. What do you do? The obvious answer could soon be “print a new one.”

Brisbane-based startup Cartesian Co. launched a Kickstarter campaign today to fund a printer that prints circuits. The EX¹ can print on materials like plastic, paper and fabric, meaning it could print paper circuits and wearable electronics.

While the creators label the EX¹ a 3D printer, it’s not exactly building towering objects. Like an ink printer, it contains two cartridges. Each is filled with a chemical. The printer lays down a layer of each and they react to form strips of stable, conductive silver nanoparticles.
