What this calculator measures

Teams pick additive or machining without knowing the quantity where each method is cheaper.

What you get

Structured summary with threshold alerts, hidden drivers and export-ready report output.

What this calculator helps decide

Use this calculator when you need to decide whether current inputs sit inside acceptable exposure bands, which driver to investigate first, and whether to reprice, reschedule or redesign before repeating the work.

What the report includes

  • Executive summary with threshold status
  • Hidden loss driver breakdown
  • Suggested actions and assumption notes
  • Export-ready PDF and CSV on paid access

What the preview does not include

The free preview shows sample structure only. Full threshold checks, hidden driver breakdown, suggested actions and export-ready PDF or CSV require paid access.

Assumptions used

  • Linear unit-cost model — excludes tooling amortization beyond entered setup.
  • Break-even uses printing setup/unit vs machining setup/unit crossover.
  • Verify material yield, scrap, and post-process costs before production decisions.
