Desktop additive PCB fabrication

Working boards, fabbed at your desk in hours.

PrometheusPCB is a desktop machine that additively prints functional, multi-layer circuit boards — so you iterate in-house at the speed of software, instead of mailing designs to a fab and waiting out the week.

On the list. We'll reach out before the first units ship. ⚡

Early access for hardware teams and labs. No spam, just build updates.

The problem

The iteration loop is where hardware goes to die.

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 collapses that loop to the length of a coffee break, so the bottleneck stops being logistics and goes back to being your ideas.

Where it fits

Not cheaper than a fab house. Faster than one.

Overseas fab house

Built for volume

5–10 days

Unbeatable per-unit cost at quantity — but every prototype revision restarts a multi-day round trip. Wrong tool for the early iteration loop.

Lab inkjet PCB printer

Built for institutions

six figures

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.

PrometheusPCB

Built for the loop

hours

A desktop machine priced for a team, not a department. Functional multi-layer boards between morning and afternoon, on the same bench you design at.

What you get

A fab that lives on your desk.

01

Functional, not decorative

Conductive copper traces and multi-layer routing that carry real signals — boards you actually test, not mockups.

02

In-house and private

Your design never leaves the building. No fab queue, no shipping, no exposing unreleased hardware to a third party.

03

Iterate, then iterate again

Spin a revision, print it, test it, repeat — several times in a day instead of several times a month.

Beta · limited first run

Bring the fab to your bench.
