Minimum Manufacturing BOM Cost Summary
(from here, production using Expertise-Embedded Systems can take production to Zero Marginal Cost.
| Category | Cost range |
|---|---|
| Core machine | $12k – $30k |
| Tooling & cutters | $1.5k – $6k |
| Grinding + lapping | $1k – $5k |
| Metrology | $1.5k – $5k |
| Test bench | $2k – $10k |
| Initial materials | $1k – $3k |
Total minimum credible setup:
- ≈ $20k (absolute low end, aggressive used sourcing, outsourced gear cutting)
- ≈ $60k (robust, low-friction build with margin for iteration)
This cost envelope supports fabrication and validation of a 2,000 psi continuous external gear pump using a minimal, reproducible, open-source workshop infrastructure.
