Did anyone measure exact noise of Prusa i3 MK2?

Hello,

I am very much considering purchasing a Prusa i3 MK2 Kit. Yet I wonder what are the noise levels of the printer? I live in an apartment building, that's why I am asking.

I was looking at a few of the reviews and even saw sounds hitting 69dbA and that's A LOT!

I am currently using a CEL-Robox printer, which peaks at 49dbA and is about fine. I put it on few vibration absorbing mats, including a thicker one under the small table it stands on and there's really no sound, compared to it just standing on the table.

Did anyone try to make the printer more silent, and see what kind of sound levels does it make?

I read about replacing the bed bearings and some vibration feet but I want to know what actually works.

Hi,

I made some noise measurement which should be buried deep somewhere in this forum, and I don't remember exactly my measures but it was definitely not 69 dB !!

What I remember is that it was within the 45~55 dB range.

There are several way to deal with the noise, in my experience the most efficient being a rubber mat, same as those you put below washing machine (1.5 cm wide), and staying in quiet mode (which is the default mode).

An additionnal efficient step is top put the printer in an enclosure, which standard now is ikea lack table based.

Going to the 40~45 dB zone is then really doable.

I'm like Jon Snow, I know nothing.

Thanks for the answer!

Do you know if I should just order some other kind of bearings for the bed(and maybe for axis rods, too)? Polymer bushings or something else, to avoid any kind of juddering noise. 🙂

Interesting. I am now able to do this this. I will post my results.

@Murloc992 Juddering? Should not happen. Are your belts too tight/loose. Stepper motors move in steps and make a noise. That is normal.

I was talking about resonance of the linear bearings of the axis'es because of them vibrating and making annoying vibration noise.

I was wondering what replacement bearings would solve the issue once and for all.

Also I don't yet have a belt to tighten, maybe in a month or two, when my kit arrives. 🙂

In the meanwhile I would love to buy the mods needed, so I don't have to take it apart later on.
