PrometheusPCB is a desktop machine we're building that prints functional, multi-layer boards with the resistors, capacitors, and inductors formed right in the layers. Most of your BOM gets fabbed, not placed, and you iterate in-house in hours instead of mailing designs to a fab.

Early access for hardware teams and labs. No spam, just build updates.
Software engineers ship a change and see it in seconds. Hardware engineers ship a board to a fab and see it next week, then find the one mistake and start the clock over. Every revision is a multi-day round trip. PrometheusPCB is built to collapse that loop into hours on your own bench, so the bottleneck is your ideas again, not logistics. And the stakes are rising: the new wave of hardware pushing into the physical world (drones, robotics, sensors, defense systems) is being built by small teams who live or die by this loop.
Resistors and capacitors are the majority of the components on a typical board, often 70–90% of the part count. A desktop machine that only prints the wiring still leaves you hand-placing all of them. Co-fired ceramic doesn't: the same process that lays down traces can form resistors, capacitors, and inductors directly inside the layers. Production LTCC has done this for decades, inside specialist fabs with long queues and high minimums. We're putting the same process on a bench.
Unbeatable per-unit cost at quantity, but every prototype revision restarts a multi-day round trip. Wrong tool for the early iteration loop.
True multi-layer printing exists today, at a price and footprint that lock it inside well-funded labs. Out of reach for most teams and startups.
A desktop machine at a price a single team can justify. The target: a functional multi-layer board with the passives printed in, between morning and afternoon, on the same bench you design at.
Printed silver traces, multi-layer routing, and embedded R, L, and C that carry real signals. These are boards you flash firmware onto and probe, not visual mockups.
Your design never leaves the building. No fab queue, no shipping, no exposing unreleased hardware to a third party. For defense and aerospace teams whose designs legally can't cross a border, in-house is a hard requirement.
Spin a revision, print it (passives and all), test it, repeat. A fresh board every day instead of every few weeks.
