Common Atomics Aeronautical Techniques, Inc (GA-ASI), a U.S. aeronautics firm, has accomplished its first check flight with a metallic 3D printed half featured onboard its SkyGuardian Remotely Piloted Plane (RPA) system.
GA-ASI’s technique for scaling metallic additive manufacturing throughout its RPA platforms has been supported by AddWorks, the session service of 3D printer OEM GE Additive, for the reason that first half of 2019.
Working with AddWorks since then, the GA-ASI additive manufacturing staff reached a milestone in February 2020 when it carried out the corporate’s first check flight of a metallic 3D printed half – a NACA inlet made in Titanium Ti6Al4V – on a SkyGuardian RPA.
“With the GE Additive AddWorks staff, we had been ready not solely to attain our brief time period goal of qualifying the NACA inlet, however we additionally labored collectively on a lot of further software improvement and qualification efforts, that are persevering with into 2020 and past,” commented Elie Yehezkel, senior vice chairman of Superior Manufacturing Applied sciences for GA-ASI.

Accelerating the adoption of metallic AM
Based in 1993, GA-ASI is a number one producer of Remotely Piloted Plane (RPA) methods, radars, electro-optic and associated mission methods. It’s an affiliate of Common Atomics, the U.S. power and protection company.
GA-ASI already has vital expertise with polymer-based 3D printing, and solely not too long ago made strides in creating its metallic additive manufacturing roadmap. After establishing the required ecosystem to assist metallic additive manufacturing purposes, the GA-ASI AM staff recognized a collection of elements and households of purposes with doubtlessly favorable enterprise circumstances.
The corporate partnered with GE Additive’s AddWorks staff in April 2019, to assist the acceleration of metallic laser powder mattress fusion (LPBF) additive manufacturing on the firm, whereas additionally strengthening the qualification of each its merchandise and processes. AddWorks supplies a step-by-step session service for adopting 3D printing, which begins with defining the enterprise case, constructing a staff, and figuring out funding alternatives.
It has helped the likes of Honda R&D Co. Ltd., in Japan, Korea Aerospace Industries Affiliation (KAIA) and America’s Triumph Group in accelerating their adoption of metallic additive manufacturing. AddWorks additionally labored on producing distinctive trend items with additive manufacturing for the 2019 Met Gala, worn by British supermodel Jourdan Dunn and Canadian actor Nina Dobrev.
Working with GA-ASI, AddWorks has supplied a variety of engineering consultancy companies, akin to design for additive (DfAM) coaching, industrialization course of improvement and supplies validation for Titanium and different metals. The target of the partnership for GA-ASI was to have its first metallic 3D printed half take flight inside a short while span, and eight months later, it achieved its aim.
“By including GE’s prior expertise and perspective to the GA-ASI’s inner management efforts, the joint staff was capable of attain the required venture momentum so as to meet their milestone,” explains Lauren Thompson, operations venture supervisor at GE Additive AddWorks and a part of the staff working with GA-ASI.

Saving time and prices with metallic additive manufacturing
Amongst its pipeline of appropriate elements for metallic additive manufacturing, GA-ASI recognized the NACA inlet to be a powerful enterprise case for the primary metallic 3D-printed half for the SkyGuardian program, after assessing half criticality and program impacts. NACA inlets, developed by the Nationwide Advisory Committee for Aeronautics, are a kind of submerged air inlet that has discovered software on many varieties of air and floor autos. By means of its session service, the AddWorks staff supported the method and manufacturing readiness of the NACA inlet with improved design and threat discount.
“Combining our deep area experience of metallic additive and finest practices from our personal additive journey with GA-ASI’s equally deep area experience of their RPA purposes allowed us to maneuver rapidly and work throughout the timelines we had set,” added Thompson.
Having accomplished a profitable check flight, the NACA inlet will now enter the ultimate qualification part for the SkyGuardian program. The additive manufactured element presents vital reductions in weight and value when in comparison with typical manufacturing course of, which requires three elements of welded shaped sheet metallic Titanium.

3D printed as a single piece on a Idea Laser M2 machine, the inlet now delivers a price discount per a part of greater than 90 p.c, weight discount of over 30 p.c, and tooling discount of roughly 85 p.c. The GA-ASI staff is now making use of finest practices and data to its wider NACA inlet half household and a number of other different elements and subsystems.
GA-ASI has additionally positioned an order for a number of GE Additive Idea Laser M2 Sequence 5 machines, to be put in at its new Additive Design & Manufacturing Heart of Excellence in Poway, California in 2020 alongside its current polymer 3D printers. Moreover, the GE Additive AddWorks staff has turn out to be trusted advisors to GA-ASI and can proceed offering consultancy and knowledgeable recommendation because it strikes to additional scale metallic additive throughout its enterprise. “It is necessary that we stay at the vanguard of producing applied sciences for our merchandise and our clients. This acceleration has pushed the maturation of our metallic AM technique and has additionally knowledgeable how we plan to strategy a a lot wider software area already within the pipeline,” added Yehezkel.
