Prometheus is Not a 3D printer – it quickly carves, drills, and shapes your PCB so you don’t have to wait for a delivery truck.
Prometheus makes real circuit boards in just minutes. When we’re prototyping, we need a tool that can give us nearly instant feedback – not feedback that comes in a few week’s time in the form of a PCB delivery. Let the PCB manufacturers make the hundreds or thousands of boards for your production run – not your prototypes. If production is your goal, Prometheus will help get you there faster.
Prometheus works by carving through the copper layer of a standard copper-clad board (FR-4 or FR-1). It can be thought of as mechanically etching the board as opposed to dealing with chemicals to perform the etching. Prometheus can also drill holes and route the shape of the board itself if you need it to fit a specific enclosure.
