Based on the “Additive Manufacturing in Navy and Protection 2024” report by AM Analysis, direct U.S. DoW spending on 3D printing and AM is estimated to exceed $2.6 billion by 2030. There are quite a few examples of the expertise getting used for navy and protection purposes, and you may be taught extra about this at our upcoming Additive Manufacturing Methods occasion in New York Metropolis. However, simply because it’s the navy utilizing AM, doesn’t essentially imply it’s all for weapons or protection readiness.
Hill Air Pressure Base, positioned in northern Utah, is without doubt one of the high installations of the US Air Pressure (USAF). The bottom has been utilizing 3D printing for a number of years, creating alternative elements for the F-22 and F-35 fighter planes. It’s additionally dwelling to the Hill Aerospace Museum, which is devoted to the historical past of the bottom and aviation in Utah. 70 plane and 1000’s of historic Air Pressure artifacts are on show on the museum, and its technicians at the moment are utilizing 3D expertise to assist protect aviation historical past.

The museum’s restoration facility bought 3D scanners and printers to help in-house preservation when authentic elements can’t be discovered.
There are numerous examples of 3D applied sciences getting used to protect historical past within the navy and past, from battleship restoration and memorial preservation to recreating prehistoric species and historic art work. Now, on the Hill Aerospace Museum, to help the preservation of its historic plane, in-house 3D scanning and printing are serving to the workforce recreate elements which are tough to seek out, just like the cooling cap pictured above and beneath.

“Guaranteeing historic accuracy is on the forefront in restoration and reveals. Our precedence is to seek out the traditionally correct half; if we’re unable to seek out the proper half, that’s once we flip to fashionable expertise to recreate our half for visible functions,” defined Brandon Hedges, museum restoration chief.
Typically, you want to spend cash to generate profits, or to put it aside. The museum just lately invested $6,000 within the 3D expertise, which has finally lowered venture prices by 80%. 3D printing and scanning has additionally saved the workforce loads of treasured time, because it used to take them months to seek out out of date parts. Now, the authenticity of the museum’s historic aviation assortment will be preserved, because of the precisely reproduced elements enabled by the expertise.

The expertise has delivered an 80% price financial savings and saved a whole lot of hours because the museum acquired the printers and scanners for restoration and reveals.
“If we determine to 3D print one thing that we can’t discover a surplus, we try to make it mix in simply as the unique,” Hedges stated. “Offering the guests with traditionally correct depictions is mission precedence for restoration and reveals.”
Based on Hedges, work on a selected half for the museum begins with the workforce members researching the half. Then, they attempt to discover an authentic, usually beginning by asking the aviation group for assist. As soon as they’ve exhausted all avenues and nonetheless can’t discover an authentic half, the workforce makes use of their gathered analysis, and scans of current parts, to find out the correct dimensions. Then, they use 3D scanning and printing to realize an correct duplicate, which improves the authenticity of the restored plane that guests come to see.
“It takes cautious changes, right lighting, and regular actions to create the proper mannequin,” stated museum intern Holly Bingham concerning the scanners the restoration workforce acquired to seize a component’s each element. “These fashions can then be 3D printed to exchange the delicate or lacking parts of a aircraft.”
John Sluder, Hill Aerospace Museum exhibit specialist, talks about one of many 3D printers the museum acquired to revive elements and to reinforce reveals Sept. 12, 2025, at Hill Air Pressure Base, Utah.
The museum’s restoration workforce tracks each half they recreate with 3D expertise. That method, in the event that they find yourself finally getting their palms on an authentic, they’ll swap it with the 3D printed duplicate.
The 3D tools isn’t simply used for restoration of their historic plane, both. Hedges stated a number of packages on the museum, comparable to schooling, curation, and reveals, have been in a position to make the most of the expertise to avoid wasting on cash and assets.

“What excites me most is that 3D printing isn’t simply serving to us restore plane elements. It’s giving us instruments to resolve on a regular basis challenges within the museum, from holding reveals protected to creating signage extra versatile,” defined exhibit specialist John Sluder. “In the long run, it means we are able to protect historical past extra successfully and share the Air Pressure story with future generations in methods which are sustainable and adaptable.”
Sluder stated that one of many museum’s most profitable 3D printing initiatives was its static signal mounts. The mounts, which maintain and show informational indicators subsequent to reveals and plane, function 3D printed ft to maintain the metal base plates of the indicators from sliding round on the concrete ground. Moreover, the fixtures for the mounts are additionally 3D printed, which makes it quick and straightforward to swap and reuse them a number of occasions.
