PRINTING
THE ARSENAL
A California company just announced a metal 3D printer it won't sell you, and plans to pack 64 of them into one Long Beach building to make missile and drone parts. The specs are striking. Some of the biggest claims are still just claims. Here's the honest read.
6 lit = machines reportedly running today at Torrance · 58 dim = the planned Long Beach fleet, over 24 months
What was announced
A printer built to feed a factory, not a market
Divergent Technologies says it's betting on a large volume of U.S. defense work — manufacturing cruise missiles and drones — using a new large-format laser powder bed fusion (LPBF) system it developed for its own use, called Monolith One.
The plan centers on a new Long Beach facility expected to house 64 of these machines, brought online over roughly 24 months, supplementing six already operating at the company's Torrance headquarters. Crucially, Monolith One is not for sale or licensing. Divergent intends to run it strictly inside its own vertically integrated system, which it describes as combining computational design, additive manufacturing, and automated assembly under one roof.
The machine
24 kilowatts of laser, by the dozen
According to Divergent, each Monolith One carries twelve 2-kilowatt lasers for 24 kW of total laser power, firing into a 700 × 700 × 835 mm build volume. That's a serious amount of energy aimed at a metal powder bed.
The factory
From six machines to a part-stamping campus
The Long Beach operation is planned at roughly 400,000–430,000 square feet of manufacturing and assembly space. At full capacity, Divergent expects it to support about 1,000 direct jobs and produce more than 275,000 individual parts — a range the company describes as running from missile airframes to warhead casings, with automotive systems still in the mix.
Divergent says its platform already supplies structures to customers including Lockheed Martin, RTX, and CoAspire. The automotive work that built the company's reputation remains part of the story, but this announcement leans hard toward military manufacturing. The strategic logic, per the company: building its own printer lets it control the entire production process rather than depend on commercial AM equipment.
The real headline isn't the laser count. It's a company choosing to design the printer, the software, the process, and the assembly line as one machine.
It's not the only such bet this month. Beehive Industries, an American jet-engine maker, announced it's buying 30 EOS M4 ONYX metal LPBF systems to service defense demand — and a separate 14-printer EOS deal made similar waves. The pattern is clear: metal and industrial additive is moving off the prototyping bench and onto the production floor.
Reading the press release critically
What's confirmed, and what's a claim
We cover industry news the way we quote repairs — separating what's demonstrated from what's asserted. Here's how the announcement sorts out:
24 kW across 12 lasers, 700×700×835 mm, four-axis scanners, 200°C plate, 1,700 m³/hr gas flow. These are concrete, checkable specifications the company has put its name to — though "stated" still means manufacturer-provided, not independently tested.
"Roughly twice the throughput of existing printers." Divergent didn't name the systems, materials, geometries, layer parameters, or measurement methods behind that comparison — and plenty of larger printers, and printers with more lasers, already exist. Treat the 2× figure as marketing until there's data.
"The first metal 3D printer designed from the ground up for scaled production of critical hardware." A bold framing from CEO and co-founder Lukas Czinger, offered without market-wide evidence. Memorable, but not a measurable fact.
The vertical-integration ambition itself. Whatever the throughput numbers turn out to be, developing the printer, software, process, and assembly infrastructure as one internal system is an unusually aggressive approach — and the part most worth watching.
// Whether Monolith One delivers the promised gains in cost, throughput, reliability, and lead time gets clearer only once Divergent publishes comparable operating data, or the Long Beach factory hits sustained production. For now, the most consequential claims remain claims.
Why a San Diego print shop cares
Same family tree, wildly different branch
Let's be honest about scale: a 24-kW laser powder bed fusion line stamping warhead casings has nothing mechanically in common with the desktop FDM and resin machines we run in Carmel Valley. We're not going to pretend a Bambu A1 and a Monolith One are cousins on the workbench.
But they're cousins on the family tree. Both build parts by adding material in layers from a digital file — the same core idea we explain in our FDM vs SLA vs SLS primer, scaled to a national-security price tag. And it's happening up the coast: Long Beach is about 100 miles north of us. When the most ambitious metal-AM bet of the year lands in Southern California, the gravity — suppliers, talent, expectations — tilts toward the whole region.
The throughline
This is the same pattern we keep flagging: additive manufacturing graduating from "make one prototype" to "make a quarter-million production parts." We watch the metal-AM frontier and the business side of the industry because it tells us where the field is heading — and increasingly, the design front end is AI-driven, with additive as the only practical way to make the resulting shapes. Divergent is the production end of that same arc, turned up to eleven. We're the local end: you bring a file, we turn it into a real part in San Diego. Different scale, same job.
Quick answers
Frequently asked
Can I buy a Monolith One?
No. Divergent has stated the machine is not for sale or licensing. It's built exclusively for use inside the company's own vertically integrated factory, alongside its computational design and automated assembly systems.
What is laser powder bed fusion (LPBF)?
A metal 3D printing process where one or more lasers selectively melt thin layers of metal powder, fusing each layer to the one below to build a solid part. It's the dominant production method for high-performance metal additive parts in aerospace, defense, and automotive.
Is the "2x throughput" claim trustworthy?
Treat it cautiously. Divergent didn't specify what machines, materials, geometries, or measurement methods it compared against, and larger or higher-laser-count printers already exist. It may prove out — but as published, it's an assertion, not a benchmark.
Does Dreaming3D do metal 3D printing like this?
Not LPBF metal printing — that's industrial-scale equipment. We run FDM and resin for prototypes, functional parts, and detail work, and we'll point you to the right service bureau if a job genuinely needs production metal AM. Either way you get an honest recommendation.
Why does a defense AM story matter to a hobbyist or small business?
Because it signals where additive is going: from prototyping into real, high-volume production. That shift pulls materials, software, talent, and expectations forward for everyone — including the desktop machine on your bench.
You bring the file. We make the part.
We don't run 24-kilowatt lasers — but in San Diego, Dreaming3D turns your design into a real, dialed-in part on FDM or resin, with 3D scanning, printer repair, tutoring, and custom PC builds under the same roof in Carmel Valley. Need production-metal AM instead? We'll tell you, and point you the right way.
