Twelve Lasers, One Buyer: Beehive Industries Just Cornered a Piece of America's Biggest Metal 3D Printers
Denver's Beehive Industries ordered multiple Nikon SLM NXG 600E machines — the largest in the lineup — and is renting the hours out. Here's why "machine time" is becoming defense infrastructure, and what any of this means for the rest of us printing in plastic.
Most 3D printing news is about new machines. This story is about someone buying a lot of the biggest ones — and what that purchase says about where additive manufacturing is headed.
As reported by 3D Printing Industry on July 11, Denver-based Beehive Industries has placed a multi-unit order for NXG 600E metal 3D printers from Nikon SLM Solutions, the metal AM arm of Nikon Advanced Manufacturing. Two details make this more than a routine equipment announcement. First, the purchase is reportedly entirely self-funded — no government grant, no dedicated defense fund. Second, the NXG 600E is the largest machine Nikon SLM makes, and ultra-large-format laser powder bed fusion capacity of this class remains genuinely scarce inside the United States.
Beehive isn't just printing for itself, either. According to the report, external customers will be able to book time on the machines directly. A propulsion company just became, in part, a landlord for laser hours.
//The Machine: What an NXG 600E Actually Is
Laser powder bed fusion (LPBF) builds metal parts by spreading a thin layer of fine metal powder and selectively melting it with lasers, layer after layer, inside a sealed inert-gas chamber. It's the process family behind much of today's flight hardware — we've covered how SpaceX leans on it in our breakdown of the 3D-printed Raptor engine. Most industrial LPBF machines have build volumes measured in hundreds of millimeters per side and run one to four lasers.
The NXG 600E is a different animal. Per Nikon SLM Solutions' published specifications cited in the 3DPI report:
Spec Plate · Nikon SLM NXG 600E (manufacturer figures)
| Process | Laser powder bed fusion (LPBF) |
| Build envelope | 600 × 600 × 1500 mm |
| Lasers | Twelve, at 1 kW each |
| Position in lineup | Largest machine Nikon SLM Solutions sells |
| Intended role | High-throughput serial production of large metal parts |
That 1500 mm Z height is the headline. It means parts approaching a meter and a half tall can be grown in one piece — no welding sections together, no joints to qualify, no seams to fail. Per the report, the configuration lets Beehive print entire vehicle bodies and large satellite substructures in a single build.
For scale, here's how that envelope compares to the machines running in our own San Diego shop:
NXG 600E
600×600×1500

Creality CR-10S
300×300×400
FDM plastic

Saturn 4 Ultra

Bar heights proportional to Z height. Same layer-by-layer idea; wildly different scale, materials, and stakes.
//The Strategy: Two Alloys, One Roof, Rented Hours
Per the report, Beehive plans to dedicate one system to Constellium's Aheadd CP1 aluminum and another to Ti-6Al-4V titanium — two alloys already established across defense, space, and aerospace additive work. Aluminum for light structures; titanium for the parts that have to be light and take abuse.
Beehive's chief operations and finance officer, Darius Ehteshami, framed the buy as a natural extension: the customers who already come to Beehive for advanced propulsion largely overlap with the ones who need large printed aerospace structures, so owning the machines lets the company serve both sides — and, in his words, double down on its history in large-format additive. Jonaaron Jones, who leads Beehive's additive parts sales, described it as carrying that large-format legacy into the next generation of manufacturing for outside customers across space, defense, and aerostructures.
The new systems slot into what 3DPI describes as a vertically integrated model — engineering, additive production, and testing under one roof — with external space and defense customers able to buy serial-production capacity domestically instead of waiting on a queue overseas.
Nikon's side of the deal is just as candid. Hamid Zarringhalam, CEO of Nikon Advanced Manufacturing, said defense manufacturers need production technology that scales quickly and reliably, and positioned the order as a step in building out manufacturing capability for the United States and its allies.
//The Bigger Picture: Machine Time Is the Moat
Strip away the aerospace vocabulary and the business logic is simple: demand from U.S. space and defense programs for very large printed metal parts is growing faster than the domestic base of machines that can make them. Whoever owns the scarce machines owns the queue. Beehive is buying capacity ahead of demand and selling it back as booked hours.
And it's not alone. The 3DPI report lays out the pattern:
Field Notes · The U.S. Large-Format Metal Buildout
Sintavia (Florida) ran a $25 million expansion that included a second Nikon SLM NXG XII 600 and facility space to support U.S. Department of Defense programs through 2030, won a DoD contract for 3D printed hypersonic propulsion components, and took $10 million from the Stifel North Atlantic AM-Forward Fund — a fund created specifically to finance American aerospace and defense AM suppliers.
3D Systems secured a $7.65 million U.S. Air Force contract to advance large-format metal AM for high-temperature aerospace structures — the government funding the buildout directly.
Beehive (Colorado) skipped the fund and the contract and simply wrote the check itself.
Ultra-large-format LPBF machines are quietly becoming defense infrastructure, the way dry docks and forging presses were in earlier eras. If you follow the money side of this industry, this is the same thesis we traced through printer makers, powder suppliers, and service bureaus in our 2026 additive manufacturing investor's guide — capacity and materials, not hype, are where the value is consolidating.
It's also a useful reality check against the other end of the market. A few weeks ago we looked at a Chinese startup promising garage-sized consumer metal printing — long on AI renders, short on verified specs. The Beehive order is what the serious end of metal LPBF actually looks like in 2026: twelve-laser machines, inert-gas chambers, qualified aerospace alloys, and buyers who measure return in booked production hours, not Kickstarter pledges.
//The San Diego Angle
Why should a San Diego reader care about a Denver company's purchase order? Because this region lives on the customer side of exactly this capacity. San Diego County is home to major defense and aerospace players and a deep bench of suppliers, machine shops, and engineering firms that feed them. When domestic large-format metal capacity expands, the queue for printed titanium and aluminum structures gets shorter for programs that touch this county — and the design freedoms of additive (consolidated parts, internal channels, lattices) get easier to justify on real programs.
There's a smaller, more personal parallel too. Beehive's model — own the machines, sell the hours — is the same economics every print service runs, ours included. We sell FDM machine time at $7/hr and resin at $9/hr, plus material. Beehive sells time on twelve-laser titanium machines. The spreadsheet math rhymes; the capex differs by several orders of magnitude. The whole industry, top to bottom, is converging on the same product: reliable hours on a well-run machine.
Straight Talk · What We Do and Don't Do
Dreaming3D does not print metal. No laser powder bed fusion, no metal powders, no flight hardware, no load-bearing or safety-critical metal parts — that work belongs with qualified industrial providers like the ones in this story.
Where we fit is before and around the metal step: fit-check and form prototypes in FDM or resin so you validate geometry in plastic before committing to expensive metal builds; 3D scanning and reverse engineering of existing parts with our Revopoint MetroY (see how that works in our San Diego reverse engineering guide); and large-format plastic parts up to 400 mm tall on our CR-10S — if plastic at scale is what you actually need, our large-format FDM guide covers that world. We'll tell you honestly which path fits your part, including when the answer is a machine shop and not us.
//FAQ
What is the Nikon SLM NXG 600E?
It's the largest metal 3D printer in the Nikon SLM Solutions lineup — a laser powder bed fusion machine with a 600 × 600 × 1500 mm build envelope and twelve 1 kW lasers, built for high-throughput serial production of large metal parts, per the manufacturer's published figures.
Who is Beehive Industries?
A Denver-based company focused on advanced propulsion and aerospace manufacturing. Per 3D Printing Industry's July 2026 report, it runs a vertically integrated model — engineering, additive production, and testing under one roof — and its new NXG 600E machines will also be bookable by external customers.
What will the new machines print?
Per the report, one system will be dedicated to Constellium's Aheadd CP1 aluminum and another to Ti-6Al-4V titanium, with the format enabling entire vehicle bodies and large satellite substructures in a single build. The exact number of machines ordered was not disclosed.
Why is ultra-large-format metal 3D printing scarce in the U.S.?
The machines are extremely capital-intensive, demand for large printed defense and space parts has grown quickly, and qualification cycles are long. That mismatch is why companies like Beehive and Sintavia are buying capacity ahead of demand — and why funds and government contracts now exist specifically to finance the buildout.
Does Dreaming3D offer metal 3D printing in San Diego?
No — we don't print metal. We print FDM ($7/hr machine time plus material) and resin ($9/hr plus material), handle 3D scanning and reverse engineering, and repair 3D printers across San Diego County. For metal parts, we can help you prototype and validate in plastic first, then point you toward the right kind of provider.
