The OWFabricator / Nano treats microfabrication the way 3D printing already works — additive, subtractive, multi-material, on one moving stage. It brings the full set of microscale primitives, every one shipping today, into a single appliance — so you can build structures in the third dimension that flat lithography was never meant to reach.
A 5-decade feature span ships commercially (0.8 mm conductive FDM → 100 nm 2-photon DLW). The framing is industry-validated (Atomic Semi: "a fab using 3D printers, microscopes, e-beam writers"). AI-NRE-zero makes multi-mode integration cost nothing. The Bambu playbook — cartridge, scrubber, untethered — is proven.
A Bambu-class enclosed appliance combining 8–12 additive + subtractive + photopolymer + metal + dielectric primitives, on a shared 5-axis stage, cartridge-fed and scrubbed, from sub-µm to 50 µm — every mode of fabrication in one machine, working on one part.
additive subtractive transform — each already ships commercially or has an open-source BOM. Every one has a recipe + controller in ofpga-fab.
| Primitive | Feature | Material / action | Class |
|---|---|---|---|
| DMD maskless lithography | 1–5 µm | photoresist patterning | add |
| ALD thin film | 1 Å/cycle | HfO₂ / Al₂O₃ / TiN / Cu | add |
| Aerosol jet | 10 µm | Ag-NP / Cu-NP conductor | add |
| Super inkjet (EHD) | 0.5–1 µm | sub-µm metal / polymer | add |
| ECAM electroplating | 33–200 µm | Cu / Ni / Au, room temp | add |
| 2-photon DLW | 100 nm | true-3D photopolymer | add |
| Conductive FDM | 0.8 mm | Cu-PLA backbone | add |
| RIE | <100 nm | anisotropic gas-phase removal | sub |
| ALE | sub-nm/cycle | atomic-layer removal | sub |
| Femtosecond ablation | 5–50 µm | cold ablation, no heat-affected zone | sub |
| RTA + scCO₂ | low-temp | anneal + dry develop | transform |
Plus VHF, the shared 5-axis stage, in-situ height metrology, a 3D structured-light scanner, and a probe station. Shared additive primitives carry straight into the PCB variant at coarser scale.
From a millimetre conductive trace to a hundred-nanometre voxel — every primitive plotted on a log scale. Additive and subtractive, all commercially available, all on the same machine.
Every primitive — additive, subtractive, metrology — operates on one workpiece in place. The part never leaves the chamber; tool-change replaces the lab's machine-to-machine handoff.
A partial-order scheduler owns process composition: which primitive runs when, with in-situ height metrology closing the loop between deposition and removal. Shared with the PCB variant.
Resists, inks, metal precursors, photopolymers as cartridge consumables; an integrated scrubber handles gas-phase chemistry. Universal AC + battery, untethered. The Bambu playbook at fab scope.
Height mapping + a 3D structured-light scanner + a probe station verify each layer before the next — the closed loop that makes multi-mode composition reliable.
Target devices that show what multi-mode 3D unlocks — each a composition of the primitives above, each reaching into the third dimension.
A 3D acoustic sensing mesh built layer-on-layer with vertical interconnect — the analog front-end stacked in volume.
True-3D polymer waveguides routed through the volume via 2-photon DLW — optical interconnect drawn in three dimensions.
Stacked translinear analog compute with embedded passives — density from the third dimension, not the node.
Every mode the OWFabricator brings together already exists — proven, characterized, shipping. Its contribution is the unification: all of them on one stage, working on one part.
Industry is already building toward software-defined fabrication, and the momentum is real — Atum Works, Fabric8Labs, Atomic Semi, Texas Microsintering and others are proving the direction. The OWFabricator carries it to its natural form: one enclosed, multi-mode machine.
Two-photon DLW (Nanoscribe), aerosol jet (Optomec), ECAM (Fabric8Labs), EHD inkjet (SIJ), ALD, femtosecond ablation — each ships commercially today. The OWFabricator composes them onto one stage, and AI-zero design cost means the integration is free; only atoms cost money.
When every mode of microfabrication lives on one bench, the structures that needed a national lab become an afternoon's work — right where the research happens.
Photonic, MEMS, analog, and quantum-adjacent teams build true-3D structures in-house — no shuttle, no queue, no shipping a design to a fab.
Design from the math, then build in the substrate where it belongs — the Periodic Stack made physical, on your own stage.
A complete microfab capability that fits in a room — domestic, self-contained, and ownable by a team rather than a nation.
