Manufacturing Systems
DMMS puts a UAS manufacturing and repair hub inside a standard ISU-90 shelter. DMS-2 puts a two-cell version on wheels. Both run local and offline.
DMMS — Drone Maintenance and Manufacturing System
DMMS is an ISU-90 housed, expeditionary UAS manufacturing and repair hub intended to support distributed production near the point of need. The current layout contains eight independent Prusa CORE One L Critical Infrastructure Edition printers, eight sealed dryboxes, a dedicated repair and computing workstation, lockable tool and component storage, and a clear center aisle for operator movement.
Four printer cells run across the rear wall and four along the right wall. The rear bank intentionally stops short of the rear-right corner so the side-wall bank can occupy it without interference. The left side is dedicated to repair, soldering, wiring, assembly, computing and final integration.
The shelter is the permanent workshop, not a transport container for equipment that gets assembled into a shop after arrival. Deployment is restoring it from transport condition to operating condition.

Production capacity
50 printed airframe
sets per day
Conservative planning value.
Published FDM quadcopter frame examples cluster around 3 to 3.5 hours of print time per airframe. At that range eight printers support approximately 55 to 64 frame prints per 24 hours. Allowing roughly 15 minutes of handling and changeover per cycle, the eight-cell configuration models at approximately 51 to 59 printed airframe sets per day.
This is structural print capacity, not a demonstrated complete-drone production rate. Ready-to-fly throughput also includes cooling and post-processing where required, electronics installation, soldering and wiring, firmware and configuration, inspection, functional testing and final acceptance. Those steps vary by airframe, electronics package and acceptance criteria, so complete request-to-deployment output is configuration-dependent.
Local job planning distributes parts across available cells and preserves cell independence, so one failed printer does not stop the remaining queue.
Transport
Logistics concept
The ISU-90 envelope supports tactical truck, strategic and tactical airlift, cargo ship, and sling-load movement.
Restraint
Printer cells, dryboxes, tools, stored material and loose mission equipment use positive transport restraint and retention features designed into the build rather than added as cargo.
Approval status
Final loaded transport approval depends on measured system weight, center of gravity, restraint design and applicable ATTLA and sling-load criteria. Those are outputs of the as-built shelter and are not claimed here.
Deployment sequence
Place shelter, establish grounding and approved source power, start the ECU, verify internal environment, release equipment restraints, initialize the secure workstation, verify cells and material, begin queued production.
Why units bring production in-house
The economics are
already documented
The Joint Counter-small UAS University at Fort Sill stopped buying commercial airframes to shoot down and started printing its own. Army-reported figures put the annual program cost at roughly $4 million before the change and about $360,000 after, with struck airframes recovered and flying again in 15 to 30 minutes. Those schematics are now moving to other installations.
What does not travel with a file is the equipment, the qualified material, the screened components or the rebuild bench. An installation that receives a design still has to build the shop around it, and that is the part DMMS delivers as one purchase order rather than a construction project.
Figures above are Army-reported and cited as published. They describe a government program, not WetWorx past performance.
DMS-2 — UAS Deployable Maker Station
DMS-2 is the same architecture at cart scale. Two Prusa CORE One L Critical Infrastructure printers, a tool wall, a workstation, drawer storage and an integrated power system on heavy-duty locking casters, with a Pelican 1660 case quick-released on top carrying airframe, electronics and consumable stock.
- 53.0 in overall width · 36.0 in cart height · 55.48 in total height with the 1660 case
- Pelican 1660: 31.59 × 22.99 × 19.48 in exterior, 5.66 ft³, 44.3 lb empty
- 48V integrated battery with 120V AC and USB-C / USB-A outputs, overload protection
- Six 120V AC outlets, surge protection, circuit breakers
- Three deployment modes: fully equipped, cart only, or case removed and carried to another unit
- Rugged aluminum frame, steel reinforced corners, textured powder coat
Printers are manufactured in the EU. No domestic-manufacture claim is made for the printer subsystem.
Utilization
What the cells produce
besides airframes
Eight cells sized for airframe production are oversized for any single training event. The capital case rests on what they make in between.
- Repair parts and spares. Non-flight-critical items reproduced from a validated file rather than ordered.
- Fixtures and jigs. Assembly jigs for the airframes, plus fixtures for whatever else the unit builds or repairs.
- Equipment brackets and adapters. The one-off parts that otherwise wait on a supply request or a machine shop.
- Range and site infrastructure. Mounts, housings, enclosures and protective covers for equipment already in place.
- Mission components. DMMS supports ready-to-fly UAS assembly, attritable systems, FPV build kits, interceptor components, accessories and spare parts within the dimensional and material limits of the selected design package.
The CORE One L platform supports common engineering polymers including PLA, PETG, ASA, ABS, PC and nylon. Structural and flight-critical applications are qualified case by case against the selected material and process set.
Air-gap architecture
Isolated by construction,
not by configuration
A setting can be changed. Removed hardware cannot.
- Wireless hardware physically removed. Printers are supplied in the CORE One L Critical Infrastructure Edition, with wireless hardware removed at the factory rather than disabled in software.
- No camera in the package. No onboard imaging on the production equipment.
- Local and offline. Printer operation and slicing require no cloud access and no vendor authorization. Any local Ethernet use is confined to a controlled internal architecture defined by the approved security design.
- Controlled removable media. Approved removable media is the data path in. An encrypted USB option and letters of volatility are available for the Critical Infrastructure Edition.
- Encrypted local storage. The system specifies hardware-encrypted storage validated to FIPS 140-2/3. Validation is a property of the selected device, not of the system as a whole. Make and capacity are selected to the customer’s requirement.
- No return path. The system produces parts and local records. No outbound telemetry, no vendor call-home, no usage reporting.
Media handling, malware scanning, custody and authorization procedures are defined in the System Security Plan for the specific installation, not asserted here.
Data path
An approved data package is prepared off-system
A government-furnished or government-approved technical data package is prepared outside the shelter. The manufacturing layer is drone-agnostic.
Transfer on approved removable media
STEP, STL and 3MF files move on approved media into the local environment. No cloud connectivity is involved.
Local slicing and cell assignment
Files are imported into PrusaSlicer on the local workstation and jobs are assigned across the eight independent printer cells.
No return path
The system produces parts and local records. It does not produce data that needs to leave.
Component screening, configuration control and what is deliberately not claimed are on the Security & Compliance page.
