Ship Universe Naval Tool
Naval Additive Manufacturing Spare-Part Buy-vs-Print & Lead-Time Tool
Compare conventional spare-part procurement with additive manufacturing using landed cost, material, machine time, labor, qualification, reprint allowance and lead time. Estimate direct savings, days of availability recovered, expected downtime value, print-farm workload, break-even economics and the readiness-adjusted advantage of printing.

Model approach:
conventional buy cost equals unit purchase price × quantity plus
entered freight and procurement cost. Expected AM material and
machine consumption are increased by the inverse of first-pass
yield to represent expected reprints. Qualification cost is
amortized over the entered expected lifetime quantity. Print lead
time combines engineering, qualification, queue, expected machine
production time, post-processing and local delivery. Expected
availability value equals positive days saved × entered downtime
value × probability that procurement delay would create downtime.
Planning and sourcing screen only.
A lower modeled print cost or shorter lead time does not establish that
a naval spare part is technically suitable, authorized, qualified or
approved for additive manufacture. Actual suitability depends on
material specification, loading, fatigue, fracture behavior, heat
treatment, surface finish, dimensional tolerance, corrosion, inspection,
testing, process control, machine qualification, build orientation,
powder or feedstock traceability, technical-data rights, configuration
control and applicable engineering authority requirements. Lead-time
estimates assume available qualified equipment and do not model detailed
printer scheduling, build packing, failed inspections, machine outages
or supply shortages. Downtime value is user-defined and should not be
interpreted as an official readiness valuation. Use approved engineering,
contracting, quality and certification processes before manufacturing
or installing any naval component.
