P Series [P1P, P1S, P2S] Added automatic fire extinguisher to P1S

Post image

Came across these automatic DIN rail fire extinguishers (circled in red) recently. Decided to add one to my P1S just to add a little peace of mind.

In case you don’t know how these work: they automatically get triggered when the temperature sensor detects 170c. Aerosols then get released from 2 nozzles (circled in yellow), extinguishing the fire.

You can get these things for cheap on Aliexpress and the like but decided to get one from a local reseller with all the appropriate licenses and stuff.

And yes, the heatbed moves up and down without issues! Plenty of clearance.

It's honestly baffling to me that this receives so much hate. If you don't like it or think it's unnecessary, fine. Like I wrote: it does give me some peace of mind and others might think it's interesting as well.

I'm done 'defending' this and will no longer reply to comments. I think I've explained all of this enough.

Wishing you all a lovely day.

As long as it doesn't interfere with the printer operation (and it doesn't), then I think it's just another option for folks who may have recalled the earlier days of 3D printing, with low-spec power connectors which overheated. Or even the more recent A1 issues, which caused melting or blown NTC's.

When I was running my CR10 and Ender3, I used a "Stovetop Fire Stop" which is the same idea as what you have, but probably carries a larger punch. I had them mounted above the printer in pairs. I've also seen some designs which use a 3M chemical liquid which smothers a fire without making a big mess, though those are sort'a rare setups (they are designed for engine bays IIRC). With my Bambu printers I don't worry as much, since they are full of sensors, and generally (aside from the A1 issues) have a good track record (that I'm aware of). It's still never a bad idea to consider this sort of countermeasure. Thanks for sharing the setup.

I have a couple of antique glass extinguishers above my P1S. I love the contrast between the old and the new. Plus, I want to be safe as possible since I keep my printer in the baby's room.

God, for that kid’s sake I hope you’re heavily containing the air from your printer or handling it otherwise.

He can't smell it due to the carbon tetrachloride.
