The Smartest upgrade you'll ever add to your 3d printer
Protect Your Prints, Your Rig, and the Building it Lives In.
BlazeCut automatically stops 3D printer fires inside enclosures. n
No wiring, no cleanup, no stress - just peace of mind
One Print Job Shouldn’t Risk Everything
3D printer fires don’t give you a warning and once they start, they move fast. If you're printing overnight, while you're at work, or in another room, there’s a real risk to your home, family, pets, and gear.
BlazeCut installs inside your enclosure and reacts automatically when temperatures spike.
It suppresses fire before you even know it started - using a clean, non-toxic agent that’s safe for electronics and safe to use indoors.
Don’t just cross your fingers and hope for the best.
Protect your rig, your room, and your peace of mind.
Fires Happen Without Warning - BlazeCut Protects What You've Worked So Hard To Build Without Hesitation - Automatically, 24/7
BlazeCut Protection For Your 3D Printer
1. Heat Is detected
BlazeCut’s special tubing constantly senses rising temperatures inside your RV’s engine bay or electrical space, staying alert even when you’re miles away.
2. Critical Temp Is Exceeded
When the air around the tubing reaches its activation point of about 221°F (105°C), the heat causes the tube to burst precisely at the hottest spot near the developing fire.
3. The Fire Is Stopped In Seconds
A clean, non-toxic agent is instantly released, smothering the flames at the source and stopping the fire before it can cause damage or downtime.

Frequently asked questions
Does BlazeCut work in open-air printers?
No. BlazeCut is designed to work inside enclosures only, where the clean agent can fully suppress the fire before it spreads.
Will it damage my printer or electronics?
Not at all. The FK-5-1-12 clean agent is non-conductive and safe for use around sensitive electronics. It leaves no residue.
Can I install it myself?
Absolutely. Every unit can be installed easily in minutes without any major modifications.
How do I know which size I need?
You can use our sizing assistant by clicking the chat bubble in the bottom right of your screen or in the main menu. Or you can calculate how much square footage you need protected and compare that to the tech specs on each product page. If worse comes to worse you can email us at: brandon@modernfiresuppression.com
What happens if the system goes off while I’m not around?
That’s the beauty of BlazeCut — it doesn’t need you to be there. It activates automatically at the first sign of dangerous heat, even if your printer is finishing an overnight print back at the office you’ll come back to a suppressed fire and a paused printer - not a total loss.
What’s the switch option for?
Our TR025FK-S and TR050FK-S models include a pressure switch that activates when the unit discharges. You can wire this to an alarm, light, or cutoff relay to stop your printer mid-job or send an alert.
