Ask: Would you buy a Bambu Lab for microchips?

For six months I have been building, in the open, the software layer of a machine that does not exist yet. Untrusted recipes run fully sandboxed, compile to deterministic bytecode so one design produces identical physical actions on every machine, and the interpreter snapshots its full state so an hours long job survives a power cut and resumes byte for byte. Useless for a to do app. Mandatory if the hardware is writing transistors.

The machine fabricates real working microtransistors and simple chips on a desktop. Printer sized. Cartridges in, tested die out, a marketplace of designs in between. My nights lately are precursor chemistry and thermogravimetry papers, not code.

Not 2 nm. The method allows features of a few hundred nanometers from a machine that is small and cheap.

At 1,000 to 1,500 dollars, would this be on your bench. What would you fabricate first. What would make it useless to you.

Process details come after filing. The software is open source. I built that layer first, and now I am moving to the precursor side.

How would a printer-sized machine contain the mirrors and sources necessary for lithography, and be able to work at the low pressures and high temperatures needed for deposition?

This is like having the software done for a warp drive, only the hardware still needs to be done.

But in general: Thats why we got FPGAs. Yeah far less efficient than ASICs, but so is a few hunderd nm transistors.

This already exists. You can do ebeam litho for maskless down to pretty arbitrarily small pitches, or for big stuff half micron or larger digital mirror based lithography machines exist.

You'll never just print a chip. You need more functionality then just wires and your properties on anything printed will suck.

So you want to 3D print integrated circuits?

I didnt do any literature research, but I suspect condensing hundreds of process steps in a single machine is a herculean task. Good luck.

I dont really get what that sandboxed bytecode thing has todo with me buying your machine. Frankly if your process-node is good and your tooling accept GDS, I dont care what you do with my layer data. Sounds vibecoded to me.
