Forward of the inaugural on-line occasion Additive Manufacturing Benefit: Aerospace, House, and Protection 3D Printing Business is operating a sequence of articles centered on the applying of 3D printing in these essential sectors. Register now for AMAA 2024 on July sixteenth to listen to extra insights from sector leaders.
Throughout an interview at RAPID + TCT 2024, Velo3D’s CEO Brad Kreger outlined how the corporate has tailored to the altering wants of the aerospace, area and protection industries.
Appointed as CEO of the steel 3D printer producer in February 2024, Kreger has witnessed the protection sector rework over the previous six months. This has been characterised by elevated 3D printer demand and an urgency to speed up adoption, pushed by international battle and rising provide chain insecurities.
He believes the “3D printing business is in a state of recalibration,” and that additive manufacturing is now not seen because the “panacea that solves all issues.”
The Velo3D CEO rationally argues 3D printing affords vital worth for low-volume, high-mix manufacturing of large-scale, mission-ready components. Right here, Velo3D’s expertise can cut back provide chain timelines from months to weeks, enabling flexibility and price efficiencies for producers.
Turning to the way to overcome boundaries in aerospace 3D printing, Kreger emphasised the necessity to advance high quality assurance capabilities and regulatory requirements. He believes rising 3D printing adoption in navy purposes will improve confidence inside the civilian aviation and aerospace sectors.
Discussing the profitability challenges going through 3D printer tools producers, he highlighted the significance of producing peripheral income streams. For Velo3D, this contains its service assist, materials growth, and Movement Developer software program choices.

3D printing for aerospace, area, and protection
The aerospace, area, and protection industries are “strongholds” for Velo3D. The corporate affords laser powder mattress fusion (LPBF) 3D printers optimized for large-format steel components. For instance, its Sapphire XC system was lately chosen to assist the U.S. Naval Nuclear Propulsion Program.
Kreger said that calculating the entire addressable marketplace for aerospace, area, and protection is difficult attributable to business fluidity. “If I have been to reply that query six months in the past, it’d be a way more conservative reply to what I would offer now,” he defined.
The Velo3D CEO acknowledged that it’s measured in billions of {dollars}, pointing to the US Protection funds handed in March 2024. This allotted over $800 billion to protection spending, a “very giant portion” of which was earmarked for additive manufacturing.
When requested how the corporate stands out in these high-value markets, Kreger highlighted Velo3D’s non-contact recoater blade expertise. Most LPBF 3D printers characteristic recoater blades that unfold the steel powder over the construct plate by bodily contact. This may create defects in components and restrict design complexity.
The corporate’s recoater blades are suspended above the powder mattress, utilizing managed air move to unfold materials extra evenly. This allows advanced 3D printed geometries and angles that “our rivals usually are not in a position to obtain.”
One other essential differentiator for Velo3D is reproducibility. “You may qualify an element on our 3D printers, after which reproduce that very same half on another system,” he defined.
This unlocks the potential for geographically distributed manufacturing. For example, SpaceX at present possesses 25 of the corporate’s 3D printers. When the US-based non-public area firm experiences a surge in demand, it leverages Velo3D’s community of contract producers to fulfill manufacturing necessities.
How scalable is additive manufacturing?
Kreger sees “huge potential” for scaling additive manufacturing, noting that the corporate’s prospects goal manufacturing purposes. This demand is especially prevalent amongst protection corporations that wish to transfer from casting to additive manufacturing. In accordance with the CEO, many of those firms have reportedly recognized the necessity for ten to fifteen 3D printers to supplant present provide chains, giving Velo3D “good visibility to proceed scaling.”
Kreger defined that 3D printing manufacturing runs are extremely variable and decided by the applying. Velo3D’s expertise is especially used for small runs of large-scale steel components. With 3D print occasions of as much as ten days, prospects typically fabricate tons of of those components a 12 months.
The time financial savings supplied by the corporate’s 3D printers are “transformative,” Kreger said. When utilizing typical manufacturing, large-scale elements can comprise between 5 to fifty totally different components, every with a novel provide chain.
These separate components, produced utilizing casting, waterjet reducing, or machining strategies, have to be assembled and individually post-processed. “That provide chain can span 12 to 18 months,” Kreger argued. He highlighted the potential for failure factors and unreliability on this prolonged course of. In distinction, additive manufacturing condenses giant components right into a single-build course of. This reduces failures and streamlines the availability chain timeline to “4 to 6 weeks.”
Kreger emphasised the flexibleness and cost-efficiency of 3D printing, notably for low-volume, high-mix manufacturing. He argued that creating a conventional provide chain is dear and solely justifies funding when producing giant volumes. As a substitute, additive manufacturing permits prospects to fabricate smaller runs of distinctive components at a low value. “That flexibility is one thing prospects actually worth,” added Kreger.
How you can improve 3D printing profitability
The 3D printing business faces a major profitability problem, particularly amongst {hardware} producers. “Tools producers throughout the board have been combating profitability,” said Brad Kreger. He believes that rising adoption is essential to overcoming this.
Kreger means that producers ought to pursue a extra holistic strategy that’s correctly monetized. This contains producing peripheral income streams past simply promoting 3D printers.
Velo3D, he defined, had beforehand been laser-focused on programs gross sales to realize core income. Nevertheless, to enhance the corporate’s high line and monetary outlook, “we’re now taking a distinct perspective and providers and assist.” This contains utility assist, materials growth, and repair assist.
“The 3D printer shouldn’t be the one part of the enterprise mannequin. Producers have to embody the entire set of values and convert that into income,” Kreger added.
Overcoming challenges for flight-ready components
The Federal Aviation Administration (FAA) continues to be transitioning from machining to 3D printing. This shift, in accordance with Kreger, requires a basic change in how part high quality is assured and controlled.
Conversely, rising operational dangers are accelerating the adoption of additive manufacturing within the protection sector. “The navy and authorities are realizing that they should pace up their efforts to be correctly outfitted,” defined Kreger.
Certainly, 3D printing is more and more used to deal with shortages of essential protection tools. The US navy is witnessing a excessive demand for missiles and a scarcity of home suppliers. To handle this, the US Navy has contracted Ursa Main to design, manufacture and hot-fire check 3D printed stable rocket motors (SRMs) to energy its SM-2, SM-3, and SM-6 missiles.
In accordance with Kreger, rising adoption in protection will enhance confidence in civilian purposes. 3D printing for navy plane will present a “wealth of information and a physique of proof” that can be utilized to ease aviation and aerospace regulatory challenges.
Safety is a paramount concern when producing components for protection purposes. Kreger factors to the stringent cybersecurity requirements demanded by the US Division of Protection (DoD), notably Safety Technical Implementation Information (STIG) compliance.
In accordance with Kreger, Velo3D is uniquely positioned to fulfill these necessities. “We’re the one producer that has STIG compliance and what they name the inexperienced standing,” he said.
This ensures that delicate file information shouldn’t be externally accessible or residually obtainable as soon as the half has been accomplished. “Knowledge safety is totally essential in defence, and we’ve made a selected business funding to supply that answer,” Kreger added.
