Physical Compilation for Multimaterial Fabrication: Architecture, Feasibility Bounds, and Verification

Abstract

VLWNC-IF-VF investigates a physically grounded architecture for a broadly capable “light printer in a box.” The proposed system combines optical addressing, chemistry-specific processing cartridges, accessible reactive surfaces, hierarchical assembly, and integrated metrology. Its guiding workflow is: describe matter → compile fabrication processes → construct → verify. The central architectural proposal is a physical compiler that jointly considers chemical selectivity, physical access, cumulative process damage, and the validity of inspection evidence. Light provides spatial addressing and measurement; material transformations rely on specified feedstocks, reaction pathways, transport, and assembly processes. A restricted executable demonstrator selects between fabrication routes and schedules inspection around modeled evidence-invalidating operations. The mathematical contribution offered for review couples optical penetration and reaction selectivity to interface reliability. For a declared equal-section architecture, optical constraints impose a maximum section thickness, while seam reliability imposes a minimum. Their intersection determines an integer feasibility interval; an empty interval rules out that route under the stated assumptions. An accompanying model derives expected accepted-stack serial service cost and establishes strict log-convexity under specified retry, screening, and defect assumptions. Additional analyses address cumulative exposure damage, reaction–diffusion blur, thermal transport, manufacturing errors, and access constraints. The release includes: A 47-page main manuscript and an 18-page mathematical companion. Hardware architecture, chemistry-specific process routes, and four proposed prototype stages. Reproducible Python calculations, synthetic datasets, figures, and nine passing computational checks. A 27-source literature ledger, explicit claim classifications, and a hostile scientific audit. Machine-readable research metadata, manuscript sections, citation files, and integrity checksums. The numerical results test restricted mathematical implementations; they are not experimental manufacturing measurements. The prototype specifications are proposed engineering envelopes. “Universal Class” denotes the project’s research objective. A working universal fabricator, general stable-matter universality, experimental performance, scientific priority, and a major breakthrough have not been established. The package is intended for independent mathematical criticism, reproducibility assessment, prior-art evaluation, and experimental falsification.
