Modern Deployable AM
• Rapid Equipping Force’s (REF) Expeditionary Lab – Mobile– Housed in standard 20ft shipping
container
– Included polymer 3D printer & CNC milling machine
– Not meant to replace parts, but to develop new parts

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

AM Advantages & Disadvantages
Advantages
Smaller logistics footprintLower total costShorter build times for certain partsHigher parts accuracyGreater range of parts
Disadvantages
Greater need for process qualificationNeed to establish quality control proceduresSmaller lot sizesGreater need for technical data formatted for CAMRequires additional training

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
Additive manufacturing will disrupt supply chains.
