the CLOUD® AERO
Engineered specifically for enclosed 3D printers - FDM and Resin, HotBoxes, CNC and laser machines, the CLOUD® AERO is a compact, self-activating fire suppression device that responds automatically to dangerous heat conditions. No wiring. No power. No setup.
Use within an enclosure whenever possible
For predictable and repeatable fire suppression performance, use within an enclosed or contained volume. In open-air environments, the aerosol can dissipate before suppression is complete.
Because the extinguishing aerosol may dissipate in open air, full suppression cannot be guaranteed in all scenarios.

Long prints come with real risk
Extended runtimes, elevated temperatures, and unattended operation increase the likelihood of fire events.
Thermal runaway, electrical faults, or material ignition can escalate rapidly - especially inside enclosed systems where heat builds.
the CLOUD® AERO is designed to respond automatically - before a small event becomes a catastrophic fire.
Watch it stop a real fire
See the Cloud® Aero activate in a real-world fire scenario and suppress flames in seconds - without damaging the machine. Real fire. Real activation. Real protection.
Simple. Automatic. Designed for contained environments.
As heat builds within an enclosure, temperatures rise toward critical levels. At approximately 170°C, the CLOUD® AERO activates, releasing a condensed potassium-based aerosol (aerosolized solid particulates suspended in gas phase) that interrupts the combustion chain reaction.
For effective suppression, the aerosol must remain concentrated around the fire source for several minutes. This is why enclosed or semi-enclosed environments provide the most reliable performance.
- Interrupts combustion at a chemical level
- Designed for electrical and mixed-material fires
- No explosive discharge and no stored-pressure release
- Safe for electronics and PCBs
Why enclosures matter
For predictable and repeatable fire suppression performance, use within an enclosed or contained volume.
the CLOUD® AERO is engineered for environments where the extinguishing aerosol can:
- Concentrate around the ignition source
- Remain present long enough to fully suppress combustion
- Prevent re-ignition
In open-air environments, the aerosol can dissipate before suppression is complete.
How aerosol fire suppression works
Effective suppression depends on two factors:
- Concentration - sufficient aerosol density around the fire
- Dwell Time - maintaining that concentration long enough to stop combustion
Enclosures enable both. Open environments reduce both.
This does not prevent activation - but it can reduce effectiveness.
On open-frame printers
the CLOUD® AERO can be used as an added layer of protection on open-frame machines, but performance depends heavily on setup. Key factors include:
- Mounting distance to ignition source
- Airflow and ventilation
- Fire size and material type
- Obstructions or shielding around the fire
Because the extinguishing aerosol may dissipate in open air, full suppression cannot be guaranteed in all scenarios.
For best results on open-frame machines:
- Mount as close as possible above likely ignition points
- Minimize airflow where possible
- Consider partial enclosures or shielding
Recommendation: Use within an enclosure whenever possible for predictable performance.

- Step 1
Clean the surface
Clean the surface where the patch will be placed with isopropyl alcohol and a paper towel (not a rag or cloth).
- Step 2
Place the patch
Place the Velcro patch onto the surface and let it cure for 24-48 hours before mounting the Cloud.
- Step 3
Mount it high
Mount near the top of the enclosure, above likely ignition sources: hotend, heated chamber, mainboard/electronics, power supply.
