Hey 3D printing fellas,

Are you worried about failures that can lead to disaster like printer catching on fire and burning down firniture and house? Do you use any kind of protection against fire?

I know metal enclosures are the best, but my printer is in the Ikea Lack enclosure. I checked connections and everything looks great, but I soldered cable on the heated bed anyway. Im not super worried tbh, but Im thinking about buying Stovetop Firestop and mounting it inside the enclosure just in case. This one is triggered with open flame only, so probably false activation is not possible. I would probably buy 2 more for kitchen.

There are also balls and other extinguisher shapes, but the one from the picture seems more recommended. Bad thing is I cant find that one availabls in europe. There are also smoke detectors, but they can only alarm you or cut the power.

What do you use? Can you recommend any good automatic extinguisher available in europe?

    Thx for input.

    I agree with you mostly, but there are also unfortunate examples even with big eu brand as well. Im not paranoid, but home 3D printer is more like production machine than kitchen appliance imo. They have moving parts and print failures happen sooner or later. Fire in a kitchen is not that rare it seems anyway.

    Before reading comments, I wasnt aware that prusa is selling fire suppression system, but I guess there is a reason for that

      Cars are a very high-vibration environment with km of wiring and some carrying high currents, flammable liquids and hot parts. With e-autos there is even more including a 50’000 Wh energy storage waiting to catch fire.

      While cars do catch fire it is unlikely to the point where they don’t need fire suppression systems.

      Some cars have fire suppression systems but those are race cars. Built differently to maximize performance. (or military vehicles)

      Similiar there are 3D-printer that might benefit from a fire suppression system but the run of the mil 3D-printer won’t need it.

      Not convinced? Look at CNC-mills or swiss lathes. Those are designed to run nonstop for years in a production environment at the highest speeds to maximize production. Most of them don’t have a fire suppression system (they do have a mist extraction/collector to prevent them from exploding).
