Here's a part of a cabinet in my wardrobe where my printer lives. It's a bit noisy with all those hard surfaces so I am just about to put up some foam padding on all 5 sides.
Is that stupidly dangerous?
You can see I have a smoke alarm there, but it won't stop a fire on its own.
Edit: the cabinet has no door, it's always open like in the photo, but the wardrobe door is generally closed. The room has some ventilation so smells do go away.
I worded this to get your attention (and that worked). Personally I think it's fine but it does make an interesting question that I want to hear the crowd opinion on.
Also, what do other people do to reduce noise when you don't have a spare room far away from your bed...? Better rubber feet isn't doing much in this case.
Look into rockwool instead of foam - it does a great Job and is not flammable.
That would just get insulation all over every print they do though. You need something more solid.
or maybe DIY air-crete panels, not as great for the temps rockwool can tolerate but OP is plastic printing, not iron forging.
You can use a concrete tile placed underneath the printer to reduce vibrations and noise
Concrete is solid and would transmit the vibrations more than other less dense options.
You need rubber feet under the slab to isolate it.

You could use a lot other material in that case. The concrete itself is a non-sequitur, your isolating the base with another base with rubber between both. Concrete, wood, plastic. Anything at that point between the two rubber pieces.
It's just better if it's more massive.
That’s a good point, I wonder if at this scale it’s negligible or not though.
Massive, won't melt, won't catch fire. Ceramic tiles would work just as well imho, though a tad lighter (which might actually be good, given the thickness of that shelf)
What about a constant white noise to drown it out? Even a running fan can be enough for a lot of people.
