Same physics. Every size.
A phased-array plate is a tiling of transducers. Add channels and area and the build volume scales with it — from a machine on your desk to an industrial cell that builds vehicles or houses. We're shipping the desktop first, and we're shipping it scanning and printing on day one.
This sounds like science fiction. It isn't.
Three things have changed that make this the right decade to build it.
Built from known hardware
Every component is off-the-shelf or standard-process: single-crystal piezos, FR4-gold PCBs, relaxor drivers, GaN amplifiers, FPGA control. Nothing here waits on a new physical discovery. The novelty is the arrangement, not the parts.
AI has collapsed the design loop
The complete machine is being built as a simulated digital twin whose software interface is the hardware interface — every design revision is tested in physics before it is built. AI writes the firmware, generates the CAD, and runs the twin in minutes instead of months. This is the reason a small company can credibly ship a machine like this now — not five years ago.
The production version builds itself
Only the first prototypes come off conventional machine shops. Once the first machine works, it becomes its own factory: every following generation is fabricated inside a previous one, atom-placed instead of milled. The cost curve after generation one is not a manufacturing curve — it's a replication curve.
The machine builds the machine.
01 · Fully simulated digital twin
The entire machine lives first as a physics-correct simulation — acoustic and electromagnetic fields, materials, control loops — with the same interfaces the hardware will have. The design is proven before a part is cut.
02 · v0, built the old way
The first machine comes off conventional machine shops: machined, wired, assembled by hand. Every component in it is off-the-shelf or standard-process. This happens exactly once.
03 · v1, built by v0
The Replicator builds the Replicator. Because parts can be assembled, a small machine is enough to make the pieces of a larger one — so each generation is finer, cheaper, and bigger than the one that made it.
What's next.
The complete machine is being built and simulated as a physics-gated digital twin — same interfaces as the hardware, moving fast. In parallel, sub-systems are prototyped and tested in hardware: we've built a lot of prototypes and keep building more.
The subsystems come together around one build volume. Scan loop first, then the build loop.
First units in partner labs and studios. Real jobs, real feedback, quarterly firmware.
The first machine made by a machine. Production shifts from a manufacturing curve to a replication curve.
The same boundary, tiled larger — up to volumes that build vehicles and structures.
| Phase | Milestone | Detail |
|---|---|---|
| Now | Digital twin + subsystem hardware | The complete machine is being built and simulated as a physics-gated digital twin — same interfaces as the hardware, moving fast. In parallel, sub-systems are prototyped and tested in hardware: we've built a lot of prototypes and keep building more. |
| Next | Integrated v0 prototype | The subsystems come together around one build volume. Scan loop first, then the build loop. |
| Then | Pilot cohort | First units in partner labs and studios. Real jobs, real feedback, quarterly firmware. |
| Later | v1, built by v0 | The first machine made by a machine. Production shifts from a manufacturing curve to a replication curve. |
| Later still | Workshop & industrial scale | The same boundary, tiled larger — up to volumes that build vehicles and structures. |
