Overview of DoD Supply Chain
• Supports multiple missions on a global scale • Involves building inventories customers can draw on
when needed • Fiscal Year 2012 supply chain figures
– Approximately 4.7 million parts1
– $95 billion worth of secondary items in inventory1
– $370 million in storage at Defense Logistics Agency (DLA) warehouses2
– Variable customer wait times of days, weeks, or months • Over 400,000 field level requests filled in range of 53 to 433 days1

Next Steps
• Evaluating decision-making tool for deployable AM that we created with VA Tech
• Creating more robust decision process to evaluate AM for reparables
• Considering standardization issues – Technical data – Materials – Process qualification – Quality control/assurance
