[INTERVIEW] Why 3D Printing is Poised to Speed up U.S. Navy Shipbuilding

Over the previous 30 years, the once-dominant U.S. Navy has steadily fallen behind the Chinese language Individuals’s Liberation Military Navy (PLAN) in measurement and manufacturing capability. In response, the Institute for Superior Studying and Analysis (IALR) helps lead efforts to revitalize U.S. shipbuilding via additive manufacturing.

The IALR’s campus in Danville, Virginia, lately hosted the fourth annual ATDM & AM CoE Summit, a protection manufacturing convention co-hosted by the Accelerated Coaching in Protection Manufacturing (ATDM) program and the U.S. Navy Additive Manufacturing Middle of Excellence (AM CoE).

I sat down with Jason Wells, Government Vice President of Manufacturing Development on the IALR, to debate the important thing takeaways and insights from this yr’s occasion. Wells outlined how 3D printing is supporting the Division of Protection’s (DOD) efforts to outpace its adversaries. 

Jason Wells will reveal extra skilled insights when Additive Manufacturing Benefit: Aerospace, Area and Protection returns on July tenth. Reserve your free ticket now.

He shared real-world use circumstances that reveal the additive manufacturing benefit for protection. In a single instance, 3D printing diminished lead instances by 95%, delivering a mission-ready part in weeks relatively than months.  

I additionally spoke with Dr. Scott Kasen, Director of Superior Applied sciences at Austal USA. He revealed how the U.S. ship producer, which sponsored and co-organized the summit, makes use of 3D printing to speed up manufacturing. 

Shifting tides: the decline of U.S. naval dominance

The U.S. was the world’s largest naval power from the top of World Warfare II via the Chilly Warfare. Nonetheless, finances cuts and rising isolationism diminished the U.S. Navy’s fleet measurement from 592 ships on the fall of the Berlin Wall to simply 297 in 2024. Amid this decline, PLAN has develop into the world’s major seafaring power, at the moment boasting roughly 370 floor ships and submarines. 

Maybe most regarding for the Pentagon, China’s shipbuilding capability is 232 instances better than that of america, in response to a leaked U.S. Navy briefing slide. The unclassified information, revealed in 2023, confirmed that Chinese language shipyards have a producing capability of roughly 23.25 million tons, in comparison with simply 100,000 tons for American shipbuilders. 

Based on the Middle for Strategic and Worldwide Research (CSIS), Beijing can restore and substitute broken vessels far quicker than its Western rival. In consequence, America’s maritime fight readiness could possibly be severely compromised if tensions escalate into an all-out battle.  

In response to those considerations, the U.S. Navy submitted its 30-year 2025 Shipbuilding Plan to Congress final yr. The doc urges lawmakers to increase America’s fleet to over 300 ships by fiscal yr 2032 and to surpass 381 vessels by 2042. Attaining these targets would require a considerable increase in home shipbuilding capability, necessitating a bigger, extra expert workforce.

Key Takeaways from the ATDM and AM CoE Summit

This yr’s ATDM & AM CoE Summit centered across the theme ‘All Palms on Deck.’It featured a stacked agenda of shows and panels addressing manpower and manufacturing shortages in U.S. Navy shipbuilding and restore. Over 450 attendees convened to debate the urgent challenges limiting AM adoption in protection and the way better collaboration, analysis, and workforce improvement can reinvigorate America’s shipyards.  

For Wells, the standout message from the two-day summit was clear. Additive manufacturing is now a vital asset to the Navy’s shipbuilding technique. “This isn’t nearly getting collectively to speak,” Wells informed me. “It’s about seeing these applied sciences take maintain and have an effect.”  

Kasen agreed, noting that the occasion was dominated by the necessity to combine AM into Navy provide chains to speed up building schedules and enhance fleet readiness. He emphasised the significance of public-private partnerships between the Navy and business in enhancing workforce improvement for additive manufacturing.  

This sentiment was bolstered by Appearing Chief of Naval Operations, Admiral James Kilby. In his keynote handle, Kilby said that by leveraging additive manufacturing, “we’re decreasing upkeep delays, and we’re shifting quicker.” He emphasised that “Each time we 3D print a component that might in any other case take 40 weeks to acquire, we’re placing extra functionality again into the Meld. That’s actual, measurable readiness.”  

Addressing mission urgency on the IALR, ATDM, and AM CoE 

Wells believes China’s rising naval energy is driving an “urgency to embrace expertise.” Confronted with mounting strain from packages just like the Columbia- and Virginia-class submarines, the AUKUS alliance, and fleet sustainment backlogs, the U.S. protection industrial base is racing to modernize.

The problem of outpacing America’s rivals isn’t just in amount, but additionally in high quality, Wells argued. Success, he added, would require cross-sector collaboration, workforce acceleration, and aggressive adoption of additive manufacturing. 

The IALR, a regional hub for expertise analysis and financial transformation in Southern Virginia, is actively engaged in these efforts. At its campus, the nonprofit hosts the federally funded ATDM and AM CoE packages. 

The ATDM program focuses on addressing the talents hole inside America’s maritime industrial base (MIB). In the meantime, the AM CoE prioritizes the modernization and mobilization of additive manufacturing expertise. 

The latter possesses a number of industrial 3D printers, together with an AML3D ARCEMY ‘X-Version 6700’ WAAM 3D printer that was delivered final yr. “The IALR’s function is to be a facilitator and steward to assist them obtain their aims of addressing the talents and expertise hole at scale and velocity,” Wells defined.            

On the workforce improvement aspect, a brand new 100,000-square-foot ATDM Maritime Coaching Middle lately opened on the IALR campus. This expanded the capability of this system’s 16-week accelerated program, which offers coaching for additive manufacturing, CNC manufacturing, high quality assurance, non-destructive testing, welding fabrication, and digital automation. 

Wells likened this system to a “manufacturing bootcamp,” with college students coaching eight hours a day, 5 days per week, throughout three shifts, reflecting the calls for of real-world manufacturing employment. “We wish them to get into these habits earlier than moving into the workforce,” he defined. 

The ATDM course consists of 600 hours of instruction, with scholar progress measured via common testing, verification, and certification. Final yr, this system educated practically 600 members, and it expects to coach 800 extra by the top of 2025. 

Early outcomes point out sturdy efficiency. Wells reported that commencement and placement charges exceed 80%. “We’re very enthusiastic about that,” he stated. “Thus far, this system has carried out extraordinarily nicely.” As soon as this system reaches full capability, it goals to teach 1,000 individuals yearly.

Internet hosting the AM CoE on the IALR campus ensures ATDM members have direct entry to related rising applied sciences used within the maritime sector. Wells referred to as this the “connective tissue” for college students, guaranteeing they’re geared up with the required information after they enter the workforce.       

Accelerating U.S. Navy shipbuilding and upkeep  

The AM CoE performs a central function in rising AM adoption throughout the U.S. Navy provide chain. It creates digital information packages for 3D printable elements. These embrace the total engineering and validation document, from printing to non-destructive testing, which might be shared with permitted Navy suppliers. 

This framework is accelerating restore cycles and enabling distributed manufacturing. By standardizing 3D printing workflows, the AM CoE helps keep away from redundant trials throughout the availability chain and eases the bottleneck attributable to proprietary silos. 

On the manufacturing entrance, the AM CoE has delivered greater than 300 3D printed elements, principally aimed toward sustaining the Navy’s getting old fleet. Engineers have used additive manufacturing to reverse-engineer elements for 40-year-old Ohio-class submarines, typically in circumstances the place unique producers have lengthy since disappeared. This functionality has develop into very important to sustaining the seaworthiness of legacy vessels.

Take the united statesMichigan, a 42-year-old Ohio-class submarine that confronted persistent points changing its corroded trim and drain valves, which often corroded attributable to harsh operational environments. The Navy turned to the AM CoE, which used laser powder mattress fusion (LPBF) and wire arc additive manufacturing (WAAM) to manufacture the tail piece and generate digital design information. With these information in hand, the Navy can now 3D print the valves on demand throughout restore cycles, reducing lead instances and enhancing the submarine’s operational readiness.

Wells cited one other instance involving the united statesHALSEY (DDG-97). The Arleigh Burke-class (Flight IIA) Aegis guided missile destroyer required a alternative bracket for its helicopter hangar door. Conventional manufacturing strategies quoted a 40-week lead time for the half, despite the fact that the HALSEY was set to deploy in simply 30 days. The AM CoE eradicated that delay by 3D printing and putting in the half in simply over two weeks.  

“That half was half of a bigger meeting, and as an alternative of ready years or shopping for the total unit, we remoted and changed it immediately,” Wells defined. “That meant the ship may return to sea as an alternative of sitting idle or cannibalizing one other vessel.” The bracket’s design file has since been inventoried as a procurable merchandise, permitting suppliers to 3D print it on demand.

Additive manufacturing at Austal USA

A subsidiary of the Australian protection prime Austal, Austal USA is one among 4 major corporations that immediately construct and keep U.S. Navy vessels, alongside Huntington Ingalls, Lockheed Martin, and Fincantieri.

The Cell, Alabama-based protection contractor adopted additive manufacturing about six years in the past and launched its first 3D-printed half shortly after. Kasen defined that the corporate now makes use of LPBF, WAAM, and wire laser additive manufacturing (WLAM) throughout its operations. Austal USA can be actively exploring chilly spray additive manufacturing (CSAM). Final yr, it bought a WarpSPEE3D chilly spray system from SPEE3D, which is now positioned on the AM CoE.

Austal USA applies additive manufacturing throughout a number of applied sciences and alloy sorts. Based on Kasen, the united statesdefense prime is 3D printing a variety of elements, together with fittings, brackets, valve our bodies, and pump elements. 

Nonetheless, he informed me, “We’re simply getting began.” The shipbuilder “will increase to different elements as we proceed to mature maritime AM with the U.S. Navy groups and industrial base.” 

For Kasen, the important thing benefit of additive manufacturing is its potential to beat provide chain delays. 3D printing allows speedy fabrication of hard-to-find or out of date elements close to the purpose of want, eliminating the lengthy lead instances usually related to castings and fittings. 

“AM is getting used to resolve provide chain points to enhance building cadence, improve fleet readiness, and help the warfighter to maintain technological benefit,” Kasen added. “The worth for prime combine / low quantity manufacturing–the sort typically wanted for emergent wants–is unsurpassed with AM.”     

AI and 3D printing 

Synthetic intelligence (AI) generated a lot dialogue throughout the summit. On day two, Meredith Gregory, the IALR’s Assistant Director, Know-how and Applications, gave a presentation on the limitations to AI adoption in manufacturing. 

This session aimed to make clear what AI is and the way it can add worth in manufacturing. “AI’s been round for fairly a while,” Wells famous. “Our objective was to assist individuals perceive the way it can speed up decision-making.”

He sees one among AI’s most promising functions as reside in situ monitoring. By capturing information throughout 3D printing, AI can detect failures and mechanically modify settings to enhance high quality and effectivity. Past streamlining manufacturing, this additionally strengthens traceability and long-term reliability, essential within the tightly regulated protection manufacturing sector.

Nonetheless, the trail to digital transformation stays fraught with uncertainty. Regardless of understanding AI’s potential, many conventional producers shared that they nonetheless discover the digital ecosystem opaque and intimidating. “It’s nonetheless somewhat little bit of the unknown,” stated Wells. “They’re attempting to determine the place the on-ramp is.”

A key takeaway from business companions on the summit, he stated, was the necessity for tailor-made steerage. Many corporations have beforehand been burned by costly digital options that failed to suit their operational DNA.

“We’re seeing lots of producers getting gun-shy,” defined Wells. “Someone would present up on their doorstep with a boxed resolution, and sadly, they didn’t all the time slot in that field.” That mismatch, Wells stated, prompted the IALR to construct a digital workforce targeted on aligning options with the precise challenges and cultures of protection producers.

Kasen emphasised that integrating digital techniques throughout Navy logistics, stock, and high quality administration stays a serious problem for Austal USA. To sort out this, the corporate is creating the Digital–Safe Trade for Additive (Digital–SEA). This practice-built system will hyperlink the Navy and part OEMs immediately with additive manufacturing (AM) suppliers and digital manufacturing information.  

Digital safety in protection manufacturing 

The rising reliance on digital threads raised questions round cybersecurity throughout the summit. Wells pointed to ongoing efforts round Cybersecurity Maturity Mannequin Certification (CMMC) compliance. This DOD framework is designed to make sure that contractors dealing with delicate info observe strong cybersecurity protocols.

Companions are additionally adopting measures equivalent to remoted servers and step-by-step encryption to safeguard design information as they transfer via the protection ecosystem. “There’s lots of follow-up occurring now post-summit,” he stated. “There’s positively urgency to get it proper.”

Kasen defined that Austal USA has carried out a number of measures to guard its digital footprint from malicious threats. The corporate follows the CMMC framework to safeguard Managed Unclassified Data (CUI) all through the whole additive manufacturing lifecycle. 

Austal USA additionally makes use of FedRAMP-authorized cloud providers along with its Digital-SEA (Safe Trade for Additive) platform. “This mix ensures safe entry management, auditability, and safe collaboration throughout distributed groups,” Kasen defined. All information exchanges are protected by layers of authentication and encrypted communications, aligned with NIST 800-171 necessities. 

Moreover, the American shipbuilder is integrating zero-trust structure ideas and role-based entry controls into its digital processes. Kasen famous that this strategy minimizes danger and enforces least-privilege entry throughout all environments. Austal USA’s techniques additionally help safe information versioning and chain-of-custody documentation, very important for assembly cybersecurity and high quality assurance certifications particular to naval functions.  

Charting a course past the ATDM Summit

Seeking to the way forward for the maritime industrial base, Wells urged that the principle problem shouldn’t be in launching new initiatives however in sustaining them. “It’s very straightforward to get distracted by the hearth of the day, and that may trigger you to maneuver aspect to aspect, relatively than ahead,” he famous.

Wells believes summit attendees walked away with extremely tailor-made motion factors, whether or not associated to expertise pipelines, provide chain entry, or engineering help. Nonetheless, the crucial now’s to keep up the main focus and guarantee “we maintain stoking that fireplace that was simply lit.”  

For Wells, the summit’s most precious end result was its function in catalysing deeper coordination throughout the U.S. protection ecosystem. “It was very encouraging to see, really feel, and expertise the power of collaboration, communication, and cooperation all coming collectively in a mission-driven imaginative and prescient,” he stated.
