Air Force’s Roper: 3D Printing ‘Going Like Gangbusters’
"I've been so passionate about bringing in additive manufacturing, and small batch digital manufacturing, to help on aircraft parts availability," Air Force acquisition head Will Roper says.

WASHINGTON: The Air and Space Forces are speeding efforts to adopt 3D printing as a major pillar of force sustainment, now making critical spare parts for weapon systems such as engine components for fighters and rockets.
“Additive and advanced manufacturing [has] been going like gangbusters across the Air Force and Space Force — printing thousands of parts for airplanes,” Air Force acquisition head Will Roper said yesterday. “We're starting to print parts for satellites, including propulsion.”
And today, the Air Force Rapid Sustainability Office (RSO) announced that it had reached a first milestone in its collaboration with General Electric to 3D print metal engine parts for aircraft — printing a metal sump pump for F-110 engines used by both F-15 and F-16 fighter jets. According to the announcement, the next phase of the program — Phase 1B , now being planned — will involve a family of parts on the TF34 engine, which has been in service for more than 40 years.
“The collaborative effort between the US Air Force and GE shows great promise toward the adoption of metal 3D printed parts as an option to solve the US Air Force's current and future sustainment challenges,” Col. Benjamin Boehm, director of propulsion at the Air Force Life Cycle Management Center (AFLCMC) said in a press release. “This capability provides an alternate method to source parts for legacy propulsion systems throughout their life cycle, especially when faced with a diminishing supplier base or when infrequent demands or low volume orders are not attractive to traditional manufacturers.”
GE originally approached the Air Force with the idea of a collaboration on 3D printed parts in 2019, and in April this year the service brought in the Defense Logistics Agency to help certify the GE-made parts for airworthiness.
ALCMC, as we reported way back in September at the Air Force Association shindig, has also been pushing to get its depots around the country certified to print their own spare parts, beginning with those not critical to life and death. Air Force leaders see additive manufacturing as key to resolving the service's serious problems in maintaining aging aircraft and infrastructure and lowering costs.
That said, the new 3D sump pump cover is an important piece of the engine.
“Compared to other parts on the F110 engine, the sump cover might have lower functionality, but is incredibly important. It needs to be durable, form a seal and it needs to work for the entire engine to function – which is of course critical on a single engine aircraft like the F-16,” said James Bonar, engineering manager at GE Additive.
The RSO-GE program is using a spiral development model, increasing the complexity and scale of parts printing with each phase. “In this program, complexity involves moving from simpler part identification, progressing to part and family of parts consolidation and eventually tackling complex components and systems, such as common core heat exchangers,” the press release said.
Roper told reporters yesterday in a Zoom briefing that due to the COVID-19 pandemic, RSO has transformed its planned Advanced Manufacturing Olympics, originally planned to coincide with the now-postponed Tokyo Summer Olympics in late July, to a virtual event to be held November. It will allow 3D printing companies to show off their wares to potential service customers via a number of challenges, including a “printer shoot-off” and a “Box of Parts” challenge where manufacturers will compete to create a drone part without a blueprint.
“We have been growing our network of small batch makers across the Air Force and Space Force,” Roper said. “I've been so passionate about bringing in additive manufacturing, and small batch digital manufacturing, to help on aircraft parts availability.”
The COVID-19 crises has proven the “additive” value of tapping into a network of small manufacturers as the Air Force has scrambled to obtain personal protective equipment for airmen at far-flung bases, he explained. Because many large producers of items like face masks are overwhelmed, the service set up the “Air Force Rapid Advanced Manufacturing Portal,” or “AFRAMP,” as a method of finding and vetting small producers to meet service needs.
“It's a portal where small batch manufacturers can make their capabilities known — show what they're able to produce — we vet them, and that then allows these small companies in aggregate to add up to large batch manufacturing,” Roper said. “We've already delivered over 11,000, different PPE devices to seven air bases that wouldn't have otherwise been able to get access for personal protective gear.”
His hope is to expand that portal to other types of advanced manufacturing in the future.
“I'm excited about scaling it up beyond just personal protective gear, and really having it be a one-stop-shop in the government for companies that can make things in small quantity — that can't mass produce, but can produce in mass if they're added up with a lot of their other sister companies.”

A tweaked DoD cloud strategy looks beyond Amazon
By: Jessie Bur A recent Department of Defense memorandum indicates that the agency wants to pursue multiple commercial cloud vendors as it attempts to modernize its IT and data infrastructure, though a single provider will still have singular influence over the agency's “general purpose cloud.” “DoD is driving toward an enterprise cloud environment that is composed of a general purpose cloud and multiple fit-for-purpose clouds,” the memorandum to Congress, released Feb. 4, said. “In addition, it should be recognized that the Department will still need non-cloud data center capability for applications that are not suited for the cloud. Over time, with the adoption of an enduring enterprise cloud strategy, the non-cloud environment should become smaller.” That general purpose slot will be filled by the awardee of the $10 billion Joint Enterprise Defense Infrastructure contract, which has been criticized for its single-award intent as giving the winner an outsized control of the defense cloud market. Many companies vying to support the Pentagon's cloud requirements claimed that the odds were stacked in Amazon's favor. The approach spurred protests and a lawsuit in fact. According to the memorandum, the fit-for-purpose environment will be made up of the Defense Information Systems Agency's milCloud suite, as well as other unnamed vendors. Throughout the cloud migration process, DoD will stick to four guiding principles: War-fighter First — any cloud solution must at all times address the needs of improving lethality while not jeopardizing the safety and mission of American war fighters. Cloud-Smart, Data-Smart — cloud solutions must streamline transformation and embrace modern capabilities while enhancing data transparency and visibility. Leverage Commercial Industry Best Practices — the cloud strategy should promote competition and innovation while preventing lock-in of one particular solution or technology. Create a Culture Better Suited for Modern Technology Evolution — the strategy will need to create a culture of learning and innovation while discouraging custom, federated approaches. This approach to commercial cloud is not entirely unexpected, as DoD Chief Information Officer Dana Deasey said during an October 2018 press event for the Defense Enterprise Office Solution cloud contractthat the agency would be delineating between general purpose and fit for purpose contracts. "This marks a milestone in our efforts to adopt the cloud and also in our larger efforts to modernize information technology across the DOD enterprise," Deasy said in a statement on the memo to Congress. “A modern digital infrastructure is critical to support the war fighter, defend against cyberattacks and enable the department to leverage emerging technologies like machine learning and artificial intelligence.” The new strategy also means that DoD will move away from a cybersecurity posture that focuses on perimeter defense and instead prioritize the protection of data and systems. “DoD will produce a unified cybersecurity architecture that addresses cloud and the needs of classified and unclassified missions and data. The capabilities will be tested and assessed independently and frequently to ensure that cybersecurity attributes remain effective against developing threats,” the memo said, adding that the CIO will determine the command and control requirements between the agency and the cloud service providers. Cloud contracts will also likely include requirements for training and workforce development to ensure that DoD can develop the expertise necessary to use and protect their new cloud environments. And any potential migrations to cloud will have to come with thorough evaluations of legacy DoD applications. “It is imperative that DoD has a cloud strategy to ensure that legacy applications are not moved to cloud without properly re-architecting them to make use of the data, security, resiliency and application advantages that cloud provides,” the memo said. “Additionally, DoD should independently test and assess cloud network security to verify security compliance and incident response and review all contractor and third-party testing results to ensure that performance and security monitoring are sufficient.” https://www.federaltimes.com/it-networks/cloud/2019/02/04/dod-to-officially-pursue-a-multi-vendor-cloud-strategy
