Prepare and execute approval-gated 3D-print stages

Why use this

1. A person describing a printable object may focus on appearance while leaving dimensions, material and machine constraints unstated. Moving directly from a generated mesh to a running printer can carry an unresolved mistake through several costly stages.

2. A stage-by-stage review record could make each proposed transition explicit. The operator could inspect the model and sliced file before any upload or machine start, with technical suitability and physical readiness checked at the appropriate point.

Why an agent / simpler alternative

Useful judgment

Translate a benign object brief into reviewable constraints and identify unresolved geometry or process assumptions.

Simpler alternative

Use an existing verified model and normal slicer workflow for a standard object.

Unsuitable when

The object is safety-critical, hazardous or requires engineering certification.

Proposed inputs

1. Name

   Explicit object brief

   Owner

   Owner

   Minimum scope

   Benign intended use, dimensions and appearance constraints

   Quality check

   Confirm fabrication intent and avoid inferred load-bearing requirements.

2. Name

   Operator-approved print constraints

   Owner

   Printer operator

   Minimum scope

   Relevant machine, material and permitted stage boundaries

   Quality check

   Verify specifications without assuming current machine readiness.

Access and setup — proposed or unknown

Proposed minimum

1. Offline model/stage plan; no printer connection or job submission.

Compatibility unknowns

1. Unknown: exact runtime, mesh/slicer tools, printer interfaces and material compatibility.

External actions requiring approval

1. Progressing between model, slicing, upload and physical printing stages; operator confirms readiness before start.

Expected deliverable and review checks

Proposed artifact

Model-review checklist, proposed sliced-file checks and a stage-approval/status manifest.

Critical checks

1. Dimensions and units remain consistent across stages.

2. Approval of one stage does not silently authorize the next or establish physical safety.

Missing output evidence

No mesh generation, slicing, upload or print is executed by this overlay.

Failure signals and proposed responses

1. Signal

   A unit mismatch changes the intended object scale.

   Why it matters

   The print may be unusable or exceed machine limits.

   Proposed response

   Hold slicing and reconcile dimensions with the approved brief.

2. Signal

   A completed file is mistaken for operator approval to start.

   Why it matters

   Physical fabrication could begin without readiness checks.

   Proposed response

   Keep the queue paused until the next stage is explicitly approved.

Effort and cost — unknown

Setup work

1. Define object constraints and stage-specific approval criteria.

Ongoing review

1. Inspect geometry, sliced assumptions and machine readiness.

Unknowns

1. Unknown: generation charges, material use, print duration and failure rate.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

An invented decorative-object plan uses inconsistent units and has model approval but no upload/start approval.

Acceptance checks

1. Scale inconsistency blocks progression.

2. Later stages remain unapproved.

Stop conditions

1. Real machine control or safety-critical design judgment is required.

Limits

1. Editorial fabrication planning; no printable-model quality or safe physical operation is established.
