An Assistant Secretary for the AF says “In two short years, 3-D printing has spread across the Air Force.Today, we print thousands of spare aircraft parts from metals and polymers, lowering operating cost by tens of millions while getting planes back to the fight faster. The need is severe: For example, three C-5s are grounded, awaiting exhaust ducts because our purchase offer of more than $430,000 for eight units did not entice a single supplier for months… When we finally received a bid, the earliest delivery was 34 weeks.”

“Using a 3-D printer, our Air Force engineers made [a] latrine panel for $300, saving $8,200, compared with the open market prices we once paid through the Defense Logistics Agency,” Roper writes. However, Roper noted that differences from printer to a printer can introduce peculiar defects not found in traditional manufacturing. To secure adequate performance and confidence in how the produced parts were made, thereby addressing craft part integration safety, especially under the stress and strain of flight, 3D metal-printing technology needs to address quality control issues such as the variable occurrence of part “lack of fusion porosity” which in turn creates a potentially lucrative opening for Sigma Labs’ technology.
