The Replicator — RH-1

Hardware specification — industrial design and Phase-1 build envelope for the free-standing three-plate machine: two mirrored chambers in one anodized column

draft v0.4 · 2026-07-30 · supersedes the desktop v0.3 envelope (rulings R9–R11: the presented and reference form is free-standing; the desktop remains a valid smaller instantiation of the same ratios, kept as a variant note in §3). Role in the pair: this is the settled-specs and optimum-engineering document — committed numbers and frozen rulings only. The science, evidence tiers, and open bets live in Transmutation as Consensus Repair; session rulings R1–R13 in REPLICATOR_CAP_STACK_RULINGS_2026-07-30.md are folded into the body below. Dimensions are canonical for renders (source model: lpoh/cad/rh1_freestanding_rev2.blend) and for the first chassis build.

1 · What this machine is, honestly

RH-1 is a free-standing anodized column, Ø460 × 1650 mm, built around three plate assemblies and two mirrored chambers: an open glass build chamber in the upper third, an active storage chamber hidden in the body below it, and between and around them the Phase-1 instrument — Ø410 perforated radiating plates, contrawound toroidal windings, ring-horn acoustic front ends with gyroid volumes, full metrology, and the multi-octave drive stack. Phase-1 capability MEASURED art: multi-octave acoustic holography, field-molded particle placement, levitation matched to material class (induction / electrostatic / acoustic — §6.0), toroidal-pulse positioning, per-layer spectroscopic metrology, chemistry-grade assembly experiments. Operating medium, by operator ruling (R11): normal atmosphere — the 40–300 kHz window a 460 mm chamber supports at single-digit dB per pass; medium conditioning is a roadmap lever, not a precondition. What it does not do: transmutation OPEN — the collar program of the main paper — makes no appearance in this unit and no claim on this spec. The honest tagline: a boundary-control instrument standing on the floor, whose upgrade path is the main paper's ladder — one chamber holds the object, one holds the matter it will become; between them, one plate.

This column is an instance, not the architecture. Every number in this document is one instantiation of a scale-free idea: a commanded boundary around a volume. The architecture fixes ratios — aperture to volume, element pitch to design wavelength, bore to aperture — and a phased boundary is a tiling, so adding area and channels grows the volume with it. Nothing in the physics privileges these millimetres; the free-standing size houses the storage twin and the services below the work, at the height a person works at. The desktop variant (Ø360 × 560, single chamber) remains a valid smaller instantiation; the workshop cell and the factory array are larger ones — same field compiler, same file format, same verbs. Read the dimensions below as this machine, and the ratios as the machine. (2026-08-01, family restructure: this demotion is now structural — the family's subject is the principles / architecture / carrier papers (Principles, Architecture, Phonons, Photons); this spec is the RH-1 instance record.)

2 · Configuration — one column, two chambers, three plates

The machine is a cylinder because its work happens between circular boundary plates — plates facing each other is the transporter configuration, and the column is the smallest polite body around a stack of them. The free-standing form follows from the stack (rulings R8–R10): the build chamber is the only open, visible volume; the storage chamber is its hidden mirror twin below, served by the same plate hardware; the middle plate is double-faced — two cap stacks back to back, radiating up into the build and down into storage; and feedstock rides the co-axial bores as a field (R10 — detail in §4). Each plate hologram carries a focusing term, so each facing pair forms a stable open resonator for the beamable bands; the walls are demoted from boundary to instrument — EMC closure, muscle band, high-angle sensing, safety.

4 · The base and the storage chamber

5 · The build-chamber enclosure — two half-cylinders on a roller track

The build chamber (the storage chamber is sealed inside the body and has no door) closes with two nested half-cylinders of low-iron glass. The rear half (Ø 444 mm, fixed) closes the back. The front half (Ø 464 mm — deliberately larger) nests outside the rear half and rides in circular roller tracks: a V-groove ring in the middle-plate carrier and a matching ring under the top band. Rotate the front half 180° and it nests fully behind the rear half — the chamber stands open across its entire front; rotate it back and the volume is sealed. No hinges, no swing radius, one motion.

Enclosure mechanism — plan view at deck level CLOSED build volume spine front (dark) seals against rear (light) · amber dashes = roller track ring OPEN — front rotated 180° full front access front half nests OUTSIDE and BEHIND the rear half — no hinge, no swing radius
Fig. 2 — The rotating enclosure. The front half-cylinder's larger diameter (464 vs 444 mm) lets it pass outside the fixed rear half; six polymer V-rollers (three per track ring) carry it with detents at fully-open and sealed. Closing engages a conductive gasket and the interlock. Tracks ride the middle-plate carrier ring and the top-band underside.

5.05 The rear arcade — high-angle RX and services (revised 2026-07-30: walls demoted to instrument, R8)

The rear arc of the build chamber carries an arcade of seven slim vertical columns behind the fixed rear glass (30° spacing across the rear 180°, aligned with plate sector boundaries). Their role under the walls-demoted ruling: high-angle sensing rows and services only — the primary aperture is the plate pair. Each column carries a dense vertical RX strip; with the plate elements transmitting they form a MIMO virtual array — the high-angle coverage the specular-gap audit requires, door in any position. Three of the seven carry the services (feed riser, power, data). Sparse-array honesty: 30° spacing ≫ λ/2, so raw beams have grating lobes — mitigated the standard MIMO way (dense within-column sampling, wideband FMCW, compressed sensing); the rotating front glass adds an aperture-diversity sweep. Plan-B upgrade path: populating the inter-column bays with phononic panels adds auxiliary muscle band and side-boundary drive where an application needs it — built out in Mechanical Construction §4; the free-standing baseline ships without them.

shield / upgrade paththe glass carries a transparent conductive (ITO-class) coating: sealed, the enclosure is a Faraday side-boundary — EMC containment now, and a latent upgrade rung: segmenting that coating into addressable electrodes turns the passive side wall into partial side-boundary drive, the ladder step between two plates and the shell (Architecture §1.2)
The enclosure is not packaging. Sealed, it completes the controlled boundary (passive today, addressable later); its interlock is the safety case; and its one-motion opening is the entire user ritual: turn the glass, place the cartridge, turn it back, touch begin.

6 · Plates, build volume, services

6.0 Channels at engineering optimum (rev 2026-07-30: the plates carry both carriers)

The machine has four physical handles on the build volume; the design never asks one channel to do another's job. Sound is the muscle, microwave is the ears and the axial drive, light is the fingertip and the eyes, the windings are the strong field and the experiment. Doctrine (operator, 2026-07-30): the three circular plate assemblies are the primary aperture for phonons and photons. Each assembly is a dual-carrier coaxial horn — three PZT elements at a common throat, the contrawound torus as ring-radial flare and strong-field source, a graded ceramic gyroid as acoustic library and EM dielectric, one perforated plate as the shared radiating face.

channelcarriesresolution / precisionspeed
acoustic — the three plate assemblies (throat → torus ring-horn → gyroid → perforated face), broadband; side panels plan B force and momentum: holds, moves, sculpts matter (the only channel with real force-per-watt); facing plate pairs form a stable open resonator (focusing term, R8) independent features ~λ/2 far-field: 0.6–0.9 mm at the air band's attenuation ceiling (~200–300 kHz), ~0.1 mm in liquid/melt; trap placement is phase/SNR-limited (~µm); sub-λ near the hologram platesms (speed of sound)
EM microwave — the same plates' spiral-slot grating (coax horn: copper inner cone → gyroid dielectric → 12 slots) bulk energy by spectral addressing (frequency is the address, chemistry is the mask), helicity, and sensing; topological registers (skyrmion numbers, R13) on the drive states focusing stays diffraction-limited (cm); positioning ~0.5λ single-aperture via toroidal-pulse signatures (SNR-limited, not λ-limited)ns
optical stem — bore sightline, bidirectional TX/RX port (R2-b) out: flying-doughnut chords (self-healing, isodiffracting) + photoacoustic writing + energy delivery; back: density-matrix state tomography (purity = roughness data) + composition (OCT / Raman / LIBS) µmfast
windings — three contrawound torus pairs, two feeds each (R5) sum mode = strong confined flux: induction levitation/heating and the potential-port experiment OPEN; difference mode = fast ring dipole: toroidal-pulse exciter and the six-circuit traveling-wave bore lift (R10) n/asum: slow/strong · difference: fast/weak

Two honesty notes that govern everything below. Precision ≠ resolution: feature spacing is wavelength-limited; feature placement is not. And below the capillary length, surface tension finishes what the field molds — the field is the mold-maker, not the polisher.

Levitation is matched to material class, not owned by one channel:

6.1 Drive and transduction — settled rulings (2026-07-19)

rulingspecbasis
channel architecture (rev. 2026-07-22 "carriers separated by surface" → superseded rev 2026-07-30, operator)the three circular plate assemblies carry both carriers — dual-carrier coaxial horns (§6.0 bullets), scale separation as the diplexer: the sub-λ Vogel mesh reads as solid conductor at GHz while transmitting sound; PZT transduction is dead at GHz while the slots don't radiate at MHz. No per-site diplexer part — the physics is the diplexer. Side paneling = plan B (auxiliary muscle/coverage). The 07-22 rationale (no diplexer hardware, optimal geometry per carrier) survives intact; its letter (carriers on different surfaces) does notone geometry, bands separated by mechanism; the carriers overlap where it matters — in the build volume, on the workpiece — and now on the plate. Detail: Mechanical Construction §3–§3b

toroidal-pulse launchthe plate's EM face is an equiangular-spiral slot grating (r(φ)=r₀ecot α·φ) with a radial ring feed at the bore rim — a flattened coaxial horn. It launches single-cycle, space-time-nonseparable toroidal and toroidal-helical pulses; the TE/TM mix α, relative phase β, and handedness are runtime drive parameters (the chord alphabet gains a helicity axis).

Revised 2026-08-03: bulk ingot-to-droplet induction melting via a shared "ingot bay beneath the deck" is dropped as a baseline claim (it does not survive against the Ø12 bore — see Mechanical Construction §3c); where pre-melted droplet/powder feedstock comes from is now OPEN — a dedicated, independently-sized melting stage is a roadmap item, not specified hereliquid-metal jetting, EBPVD — industrial art; energy ladder ≈ 0 / 1 / 8 / 22 MJ/kg (Fe)

Canonical source model: lpoh/cad/rh1_freestanding_rev2.blend (the old desktop model is archived inside it as RH1_v1_OLD). Canonical numbers: Ø460×1650 body; build chamber glass Ø444×460 at 1060–1520; plates Ø410×12 with Ø12 bores (resized 2026-08-03, was Ø130 — see Mechanical Construction §3c) at 655 (deck), 1048–1060 (middle), 1520–1532 (top); tori Ø290 major / Ø60 tube at 600, 998, 1575; gyroid horn cones throat Ø36 → Ø404 (model cells enlarged ~10× for legibility; production cells 2–5 mm); 4 mm walls everywhere. Finishes: shells in champagne anodized aluminium (satin, faint brushed grain); plate faces dark machined metal (let the slots and hole-field show — they are the product's face); ceramic gyroid warm bone; contrawound windings two-tone copper/bronze (the signature detail — show them in any cutaway); low-iron glass with a just-visible tint; LED ring warm white. The hero shots are (a) the closed column — one luminous chamber in a quiet monolith — and (b) the quarter section cut (live boolean in the model, R2_SectionCutter): shells 4 mm thin, storage rows, three tori, gyroid horns. The machine should read as an instrument, not an appliance: the closest kin are a watchmaker's bell jar, a telescope pier, and a transporter pad — in that order of restraint.

Register note for the deck. Renders may show the machine assembling an object from the mold field — that is Phase-1 capability class MEASURED at mesoscale. Do not depict on-device transmutation or claim it in copy; that program is OPEN and lives in the main paper's pre-registered ladder. The pitch is strong precisely because its body is buildable art and its ceiling is honest.
