BlazeCut 3D Printer Fire Suppression System - Includes Mounting Hardware

Shipping to the Continental US Only

Over the years 3D printers have gotten safer, but at 3DUPfitters we think of them as an oven:  even though they are perfectly safe they're still not something you'd want to leave unattended. It's rare, but just like an oven, it's still possible for a 3D printer to catch on fire.

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 and plastic mounting pieces designed by 3DUPfitters.  

Note that because 3D printers are already hot when they're printing, and this device uses temperature to trigger, your printer has to actually be on fire to trigger it.  In other words, your printer is probably toast by the time this goes off.  The good news, though, is your house won't burn down.  Watch the two videos and you'll get an idea of how it works.

Includes

• BlazeCut automatic fire suppression system, two mounting brackets

• 4 M4 14mm cap head screws and 4 M4 nuts.

• STLs to 3D print your own other mounting pieces 

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:

• Electrical non-conductive
• Non-corrosive
• Resistant to temperature changes
• Leaves no residue
• Does not damage equipment or objects
• Zero ozone depleting potential

The above video was from Blazecut and used the Lack enclosure, but we wanted to test it with one of our all-acrylic enclosures to see what would happen. Unfortunately, it's winter here and 32 degrees outside, so the temperature inside the enclosure took longer to heat up to the trigger temperature.  On the other hand, it was a good torture test that shows the acrylic did not catch on fire despite there being a large fire inside.

The BlazeCut™ T series comes in three sizes with three different amounts of gas that are designed to work with different volumes.  Please refer to the table below for details.  

For more information check out the manufacturer's product page or the manual.

Installation

The BlazeCut should be installed at the top of the enclosure, with the temperature sensor configured on the side of your printing containing the electronics since that's the most likely to catch on fire if there is one.

If you purchase a BlazeCut with your 3DUPFitters enclosure it will come with holes predrilled on the top and the plastic mounting pieces included.  If you purchase these afterwards you'll need to drill holes yourself, and you can download the STLs for the mounting pieces.
