Forward of the inaugural on-line occasion Additive Manufacturing Benefit: Aerospace, House, and Protection 3D Printing Trade is operating a sequence of articles targeted on the appliance of 3D printing in these essential sectors. Register now for AMAA 2024 on July sixteenth to listen to extra insights from sector leaders.
TCT 3Sixty 2024 opened with a keynote from Digby Gill, the British Military’s Head of Superior Manufacturing (AdM) Functionality Coherence. Titled Additive Manufacturing for UK Defence, his discuss targeted on the British Military’s use of 3D printing for the manufacturing of mission-critical components close to the entrance traces.
He outlined how the British Military has built-in additive manufacturing into its operational workflow, and highlighted the essential problem that should be overcome to extend adoption within the protection sector.
Moreover, Gill shared his ideas on the way forward for 3D printing for protection, arguing that additive manufacturing “clearly has a big half to play in the way forward for army capabilities.”

What issues does 3D printing clear up for protection?
Based on Gill, the British Military has witnessed a rising reliance on business suppliers to fulfill provide and manufacturing calls for. He argued that the British Military has “misplaced contact with its skill to unravel its personal issues.”
Gill believes additive manufacturing is the proper know-how to reverse these issues and rebuild the Military’s manufacturing capabilities. Specifically, he argued that deployable 3D printing know-how can overcome prevalent points associated to insecure provide chains and lengthy lead instances.
Over latest years, threats have emerged that jeopardize the availability of worldwide items. These embody COVID-19 pandemic, battle in Ukraine, assaults on delivery within the Purple Sea and Gulf of Aden, and geopolitical stress within the Taiwan Strait and South China Sea. This poses challenges for protection forces that always require mission-critical spare components at quick discover.
Gill argued that, slightly than ready weeks for the availability chain to ship elements, 3D printing can be utilized to supply essential spare components when and the place they’re wanted. This could allow army forces to get extra tools again within the battle.
He additionally highlighted problems with obsolescence. Lots of the unique producers of the Military’s {hardware} both don’t exist or are unable to fulfill manufacturing calls for. 3D printing is properly suited to unravel this drawback, because of its skill to manufacture spare components from scratch and to particular design specs.
The British Military’s 3D printing capabilities
The British Military has been exploring the capabilities of additive manufacturing for the previous 5 years. Gill defined that the Military possesses polymer 3D printing capabilities which have developed from a “hobbyist degree” to the manufacturing of purposeful components.
On the metals facet, the British Military leverages know-how from Australian 3D printer producer SPEE3D. Having bought its first XSPEE3D chilly spray 3D printer in 2023, the British Military lately adopted the corporate’s new Expeditionary Manufacturing Unit (EMU).
The EMU combines the XSPEE3D, which might 3D print fully-dense metallic components measuring ⌀0.9m x 0.7m, with the SPEE3Dcell post-processing unit.
These two programs are constructed inside metallic containers, permitting them to be positioned on the again of a truck and transported wherever within the discipline. This aligns with the British Military’s objective of working 3D printers “as near the frontline as doable,” defined Gill.
Not like different metallic 3D printers, SPEE3D’s chilly spray know-how doesn’t use inert gasses or delicate lasers that may be simply broken in transit. As a substitute, it fabricates metallic components by firing metallic powder at a substrate at supersonic speeds. This makes SPEE3D’s know-how inherently rugged, and splendid for deployment to energetic army environments.
Furthermore, SPEE3D’s TwinSPEE3D software program is designed to be intuitive, routinely processing 3D print information and producing optimum instrument paths.
That is essential for the British Military, which requires the common soldier to function its 3D printers. Gill defined that “3D printing will not be a commerce within the Military, and it’s not anybody’s full-time job,” that means the know-how must be simple and simple to make use of.
Gill additionally recognized the continued growth of the British Military’s digital repository, which is getting used to retailer all of its 3D printable designs. This database ensures the manufacturing of “repeatable components” by standardizing the additive manufacturing course of all through the Military.
3D printing excels in army trials
The British Military’s adoption of the EMU is a part of a two-year experiment exploring whether or not it will possibly “design, print, post-process, and guarantee metallic components” close to the entrance traces and “on the transfer.”
As a part of this initiative, the British Military lately started 3D printing spare components within the discipline for the primary time at Train Steadfast Defender, NATO’s largest army train because the Chilly Battle.
Utilizing its XSPEE3D, personnel from 9 Theatre Assist Battalion, Royal Electrical and Mechanical Engineers (9 REME), have 3D printed alternative components for outdated automobiles. These embody caps for jerry cans, brackets for communications programs, and mounts discovered inside engine bays.
Gill additionally pointed to a bilateral settlement which has seen the British Military leverage additive manufacturing to assist the Ukraine armed forces’ ongoing warfare efforts in opposition to Russia.
Throughout AM Village 2024, a European Defence Company occasion held in Belgium final month, British forces created technical information packs (TDPs) for 70 totally different spare components. TDPs embody the digital engineering info wanted to 3D print the elements. The objective was to offer Ukrainian troops with the means to supply essential spare components with additive manufacturing.
Ukraine can now use the TDPs to fabricate the components utilizing its arsenal of business 3D printers. This contains WarpSPEE3D chilly spray programs from SPEE3D and Excessive-Velocity Extrusion (HSE) 3D printers from 3D printer producer Essentium.
Based on Gill, the four-day venture additionally noticed the British Military 3D print 133 purposeful components, 20 of which have been metallic. Gill views AM Village 2024 as successful, characterizing the occasion as “a tremendous collaboration with our European allies” which resulted in “nice assist to Ukraine.”
The way forward for 3D printing within the British Military
Gill believes that challenges nonetheless should be overcome earlier than 3D printing may be extra broadly adopted for protection functions.
“We’re nonetheless looking for out what AdM appears like within the Military,” defined Gill. “Though that’s come a great distance, it nonetheless must go additional.”
He pointed to limitations in coaching and personnel, arguing that the “applied sciences have progressed faster than our skills to make a syllabus.” Wanting forward, Gill envisions a devoted college and coaching program that can filter out those that are properly suited to additive manufacturing.
Rising technical specialization within the British Military, particularly regarding computer-aided design (CAD) and supplies science, will enable AdM to turn out to be “a extremely impactful” know-how for protection.
