Over the years 3D printers have gotten safer, but at 3DUPfitters we think of them like an oven: even though they are perfectly safe they're still not something you'd want to leave unattended. It's very, rare, but just like an oven, it's still possible one could ignite.
And that's where this cool device from BlazeCut™ comes in. The extinguishing agent is stored in a tube you attach to the top of your enclosure. When a fire occurs the heat causes the tube to rupture, releasing the extinguishing agent. There's no power supply, nothing to calibrate, just a tube you install with zip ties.
BlazeCut™ uses liquified gas, HFC-227ea fire extinguishing agent. The agent is a worldwide known and accepted gaseous clean agent used for total flooding fire suppression applications with very high effectivity, zero ozone depletion potential, and safe to people. It's really the best choice for 3D printer enclosures:
Resistant to temperature changes
Leaves no residue
Does not damage equipment or objects
Zero ozone depleting potential

The BlazeCut™ T series comes in two sizes, the T100 for small enclosure such as the Prusa or Ender 3, and the T200 for larger enclosures like the CR-10 series and Ender 5. Be sure to order the right one for your enclosure.
