Description
Let's face it, most of us will go our entire printing lives without an actual fire. That said, it can happen. This is the Fire Suppression unit for your 3D printer, that may stop a bad situation from getting worse. If it is activated, unlike many other solutions, it will extinguish the fire without damaging your Printer or its electronics.
Please note - this can only be shipped via ground shipping.
The BlazeCut TR032FK / TR045FK is a compact, automatic fire suppression unit designed specifically for small, enclosed spaces like 3D printer enclosures.
The TR032FK is Tailored for use with Small/Medium Sized Enclosed Printers (e.g. Print Bed of ~255x255 mm)
The TR045FK is Tailored for use with Large Sized Enclosed Printers (e.g. Print Bed of ~350x350 mm), dual printer racks, enclosures with multiple power supplies, heated beds, or filament dryers.
This self-contained system provides fast, mess-free fire protection—no wiring, external power, or manual activation required.
The system consists of a black, abrasion-resistant detection tube filled with FK-5-1-12, a Clean Fire Suppressing Agent. When the temperature inside the enclosure reaches approximately 267°F (±6°F), the tube melts at the hottest point, forming a nozzle that releases the agent directly at the source of the fire. The result is instant, targeted suppression that won’t damage your printer, electronics, or surrounding space.
Because it operates silently and without residue, the TR032FK/TR045FK is ideal for workspaces, studios, classrooms, and any area where enclosed additive manufacturing takes place. It installs directly into your 3D printer enclosure and is completely maintenance-free.

WHAT MAKES FK-5-1-12 DIFFERENT?
FK-5-1-12 is a non-toxic, non-conductive, and residue-free clean agent that’s safe for people, electronics, and small enclosed environments. It’s one of the most environmentally responsible fire suppressants available, with zero ozone depletion potential and very low global warming potential, making it ideal for indoor use around sensitive hardware and humans.
