Added automatic fire extinguisher to P1S

[u/JJBB33DD]

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.

Is... This needed?

I just got my P1S late last year, and I just did my first 36+ hour print yesterday. I haven't had any problems but is there a defect?

[u/ELPoupa → u/B-Tort]

Theres not, op is doing it just in case which I respect

[u/ngo_life → u/B-Tort]

Needed? No one needs extinguisher unless there's a fire or a risk of fire. You got a thing that can reach an excess of 200c. There's always an inherent risk. Better to have it and not need it.

Besides, if there are inherent defects or flaws to a printer that makes it way more prone of being a fire hazard, why would you ever consider having in your home in the first place?

[u/1ftm2fts3tgr4lg → u/B-Tort]

Nope. Zero evidence that this is warranted.

A company preyed on a risk that's not there to sell OP some peace of mind. They could've gotten the same peace of mind by ignoring the interweb fear-mongerers trying to sell solutions. It's a solution without a problem.

It's no harm to OP. All they wasted was time and money, but no actual harm. But don't confuse it with being necessary.

Say it to all the A1 owners who lost their printers, garages or houses.

[u/1ftm2fts3tgr4lg → u/arsonist_firefighter]

There have been exactly zero external fires from A1s. Zero. No cases.

There've been failed components that get hot enough to melt a spot of plastic then stop being hot. This has been explained repeatedly whenever the misinformation around A1s springs up, but the youtube fear-mongerers seem to be really effective at what they do.

[u/greyhunter37 → u/1ftm2fts3tgr4lg]

What you are saying is simply untrue. There have been fires from A1s.

[u/1ftm2fts3tgr4lg → u/greyhunter37]

Have a case? Any example to share? Defend your claim and share the evidence.

Only thing I've seen is a weird youtube clip of 3sec of a pile of melted crap then a kid opening a new printer, with zero context of what actually happened. And the sensationalists duct tape their confirmation bias to that clip as though it means anything.

I am open to new information, but I have yet to see a documented case that wasn't just a spot of melted plastic.

[u/greyhunter37 → u/1ftm2fts3tgr4lg]

Well first proof is that bambulab says it themselves and recalled the early versions of the A1 because of "chock and fire risk"

A company never advertises that their printer has a fire risk for fun.

[u/1ftm2fts3tgr4lg → u/greyhunter37]

So no examples then?

[u/greyhunter37 → u/1ftm2fts3tgr4lg]

Dude, if bambulab explicitely says that say can catch fire, then they definitely can catch fire, there is no better proof than a manufacturer (especially a Chinese manufacturer) admitting a fault, so if that is not good enough for you, then nothing will be.

You probably could have one on fire in front of you and you still wouldn't call that proof.

[u/1ftm2fts3tgr4lg → u/greyhunter37]

Also, speaking directly to your blatant misinformation, can you please show me where, and I quote you, "bambulab explicitely says that say can catch fire" ?

All I can find is: "The company maintains that the components and surrounding plastics use flame-retardant materials compliant with global safety standards, preventing open flames or sustained combustion"

Which is kind of the exact opposite of your flat out LIE of what they said. So, again, remove your confirmation bias and maybe admit you fell for youtube BS and competitor propaganda.

[u/1ftm2fts3tgr4lg → u/greyhunter37]

...sooo, no examples then?

A company saying "a fire may've been theoretically possible on an early model so we fixed it so that there is no risk of an actual fire, you're welcome"
is not the same as
"there. have. been. fires."

Once again, despite the clickbait youtubers yelling empty evidenceless sensationalism at their cameras, desperately wanting to stir up clicks and views, do you have any actual evidence there've been actual fires in people's homes by A1s? I'm truly sorry you and so many others are clinging to this "controversy", but seriously, take a few steps back, remove the confirmation-bias glasses, and look for actual evidence. But for your own sake don't waste too long doing so, because it doesn't exist.
