Naval Additive Manufacturing Spare Part Buy vs Print Lead-Time Tool
Compare procurement and additive-manufacturing response for a naval spare without assuming that a printable geometry is automatically approved for service. Simple mode screens cash cost, lead time and mission-delay exposure. Advanced mode adds approved stock, qualification status, print yield, machine queue, post-processing/NDE, bridge-part replacement, recurring demand and lifecycle supply economics.

Need qualification, yield, bridge-part and lifecycle inventory logic? Click Advanced above.Advanced distinguishes approved permanent AM, temporary bridge use and qualification-pending cases, then models stock shortage, expected print attempts, queue, NDE/post-processing, annual demand and inventory carrying cost.
Fast Buy vs Print Mission-Response Screen
Simple mode assumes the print pathway is technically authorized for the modeled service. Use Advanced when qualification, bridge-only use or approved-stock restoration matters.

AM Qualification & Part-Readiness Controls
Logistics / economic screening only: this tool does not determine whether a naval part is printable, approved for installation, interchangeable, flight/submarine/Level I/SUBSAFE suitable, or acceptable for temporary service. Technical authority, source approval, material/process qualification, inspection/NDE, configuration control and applicable safety/criticality requirements govern actual use.
2026 naval AM context:
NAVSUP WSS's Additive Manufacturing Source Approval Request guidance states that AM source approval can also require separate AM process and material qualification by the appropriate Navy engineering authority, including NAVSEA for maritime parts. The Navy's Submarine Industrial Base program is moving approved AM parts into standard production and supply, while recent Navy technical requirements continue to emphasize qualified materials, processes and engineering controls rather than treating 3D printing as an unrestricted substitute for procurement.
