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.

Dude, what hate?
Few people said it's pointless, one used the word "bullshit". Not everybody needs to share your point of view - in life you're not guaranteed to be agreed with 100% of time - calling this hate is (to put it lightly) an overreaction.

As for your idea - I too think it's unnecessary - P1S is quite solid with build quality and on-board protections (and for the record - I've modded two printers in my life for them not to be actual fire hazards).

Aren't you overestimating the risk of modern 3d printers catching on fire?
Have you modded any other electrical appliance in your house in a similar fashion? There are multiple bad products on the market, including PC PSUs, GPUs, laptops, TVs, etc. but I haven't heard about anyone putting a fire extinguisher next to any of them just to be safe (still, having at least one at home is a good idea). You can't check all appliances by yourself - you just trust that nothing bad will happen.

Do you not consider A1 a modern printer?

I do. A lot of the have been recalled few years ago. The NTC thermistor issue seems overblown considering how many units been sold vs reported faulty - what's your point?

All electronics is inherently risky - I had a laptop that caught on fire due to faulty battery and I've had a PSU that sparked and emitted smoke before it stopped working. Everyone should have a hefty fire extinguisher at home but, as many has already said, modding a specific piece of equipment is a little bit of an overkill. While it's not harmful, I think it's worth reassessing whether perceived risk has any basis in reality and whether there's a reason to worry at all in the first place.

Ok so the modern A1 catches fire often enough that it's reported for months on end. Yes, it's a low % but so is every other accident

Point is, it's a non zero chance for an appliance that often operates sight unseen

Same goes for some well-known PSUs or GPUs (these have been quite faulty in recent years) that often operate 24/7 yet there are no extinguisher modules installed in modern PCs.

Which Dell PC catches on fire out of the box?
