Sheet 2 — non-conformance reports

Real parts generated by AI models from manufacturing prompts, graded by geometry scripts — drag to inspect each exhibit. Every card is a non-conformance report: the prompt asked for a manufacturable part; the checks show what came back.

NCR 3d-mold-001score 50/100
Injection molding~80mmShap-E (Hugging Face demo, June 2026)

"a simple wall hook that can be injection molded as a single plastic part, about 80mm tall"

Watertight solidPASS
Wall thickness ≥ 1mmPASS
Draft angle ≥ 1°FAIL
No undercutsFAIL
Findings: Walls are dead vertical — zero draft. The part would scrape and stick on ejection from the mold. Geometry traps itself relative to the mold pull direction — a rigid two-part mold cannot release this part.
NCR 3d-print-001score 67/100
FDM printing~100mmShap-E (Hugging Face demo, June 2026)

"a desktop pen holder designed for FDM 3D printing without supports, about 100mm tall"

Watertight solidPASS
Wall thickness ≥ 1mmPASS
Printable overhangsFAIL
Findings: Down-facing surfaces steeper than the 45° rule with nothing beneath them — they collapse without support material.
NCR 3d-mold-002score 25/100
Injection molding~70mmShap-E (Hugging Face demo, June 2026)

"a small rectangular enclosure base with four walls and an open top that can be injection molded as a single plastic part in a straight-pull mold, about 70mm wide"

Watertight solidPASS
Wall thickness ≥ 1mmFAIL
Draft angle ≥ 1°FAIL
No undercutsFAIL
Findings: Walls run thinner than 1mm at this part's stated size — short shots in a mold, fragile off a printer. Walls are dead vertical — zero draft. The part would scrape and stick on ejection from the mold. Geometry traps itself relative to the mold pull direction — a rigid two-part mold cannot release this part.
NCR 3d-mold-003score 50/100
Injection molding~40mmShap-E (Hugging Face demo, June 2026)

"a round knurled control knob with a blind shaft socket on the underside, to be injection molded as one plastic part, about 40mm in diameter"

Watertight solidPASS
Wall thickness ≥ 1mmPASS
Draft angle ≥ 1°FAIL
No undercutsFAIL
Findings: Walls are dead vertical — zero draft. The part would scrape and stick on ejection from the mold. Geometry traps itself relative to the mold pull direction — a rigid two-part mold cannot release this part.
NCR 3d-mold-004score 50/100
Injection molding~30mmShap-E (Hugging Face demo, June 2026)

"a C-shaped cable clip that snaps over a round cable, injection molded as a single plastic part in a straight-pull mold, about 30mm tall"

Watertight solidPASS
Wall thickness ≥ 1mmPASS
Draft angle ≥ 1°FAIL
No undercutsFAIL
Findings: Walls are dead vertical — zero draft. The part would scrape and stick on ejection from the mold. Geometry traps itself relative to the mold pull direction — a rigid two-part mold cannot release this part.
NCR 3d-print-002score 100/100
FDM printing~90mmShap-E (Hugging Face demo, June 2026)

"an L-shaped wall bracket with a flat horizontal shelf, designed to be FDM 3D printed without supports, about 90mm tall"

Watertight solidPASS
Wall thickness ≥ 1mmPASS
Printable overhangsPASS
NCR 3d-mold-001score 0/100
Injection molding~80mmTripo (free tier, June 2026)

"a simple wall hook that can be injection molded as a single plastic part, about 80mm tall"

Watertight solidFAIL
Wall thickness ≥ 1mmN/A
Draft angle ≥ 1°FAIL
No undercutsN/A
Findings: The mesh is not a valid solid — it has holes or non-manifold edges. Walls are dead vertical — zero draft. The part would scrape and stick on ejection from the mold.
NCR 3d-print-001score 0/100
FDM printing~100mmTripo (free tier, June 2026)

"a desktop pen holder designed for FDM 3D printing without supports, about 100mm tall"

Watertight solidFAIL
Wall thickness ≥ 1mmN/A
Printable overhangsFAIL
Findings: The mesh is not a valid solid — it has holes or non-manifold edges. Down-facing surfaces steeper than the 45° rule with nothing beneath them — they collapse without support material.

Checks run on the raw downloaded mesh, normalized to the prompt's stated size. Thresholds and known limits are published on the methodology sheet. First result only — no cherry-picking in either direction.
