Too much fun, banned from overnight printing
So the MK2 is my first 3d printer and I've been going a little crazy with the printing having a lot of fun. I started learning Fusion 360 which is cool but driving me a little crazy. Anyway, the printer is located next to my bedroom and my wife says I am no longer allowed to print anything overnight as it's too loud. I told her I switched it to quiet mode so it'll be quieter but she's not convinced. I told her I wanted to print a really cool castle which takes 23 hours but she adamantly refuses. I told her the prints are for the children but she's not going for that either. It has to be shutdown by 11:30pm. I'm at a loss about what to do.

Sound proof enclosure?

I was thinking of putting up a couple of sound baffle foam wall squares, not sure how much help it would provide. Unfortunately the printer is in the corner sharing a wall with the bedroom on the other side. I have no other spot for it.

Re: Too much fun, banned from overnight printing
I presume you have anti-vibration feet under the printer?
They help a bit, but an enclosure would be better.
I am very fortunate in that my wife encourages the printing and most of my prints run overnight. One printer is currently on a 60 hour job and the other is running a series of 12 + hour prints.
Fortunately, the printers are in the basement and we sleep on the first floor...

Thanks! Will have to print one of these.

I have the felt pads that were included with the printer. Where can I get the anti-vibration feet? Do I print them out?

If only I had a basement, that indeed would be a better spot. Wow, a 60 hour print?! I guess that means it's printed at .05 detail mode?
Re: Too much fun, banned from overnight printing
You can find the feet here. http://www.prusa3d.com/prusa-i3-printable-parts/ I've been using them and they do a good job of reducing the low frequency "rumble" that is transferred through the table.
If you slice them yourself rather than use the included gcode, you will want to print them with zero top and bottom layers, 0% infill, and four perimeters/shells.

No, at 0.2mm layers. But very slowly and with a whole load of support and a huge raft. (Stegosaurus spine at 12:1 scale).
I used different A/V feet this time: http://www.thingiverse.com/thing:91720 I find these slightly better than the PF ones.

You scaled it x12 times? I'd like to see how that comes out when it's done. Must be huge!

Looks good, did you use the jumbo stl or the regular one?

Good to know, I think I'm going to give these one a shot: http://www.thingiverse.com/thing:91720
Re: Too much fun, banned from overnight printing
Re the dampers; I just printed the V3.STL.
Sorry... Scale 1:12 = 1/12th scale The original files on thingiverse are 1:20. Just finishing off the T-Rex.
We have a museum (with real dinosaur bones) which we take to exhibitions. I currently have a coupe of weeks off the exhibitions, so printing these for display.

Wow, what a difference, thanks! Significantly quieter. Should I put felt pads on the bottom? It doesn't fit exactly so maybe I'll try the jumbo size so it sits inside the square.

Cool, I'd like to see how it comes out.
Re: Too much fun, banned from overnight printing
Hi Prusayo,
Typically when you try to fight against noise, there are two type of sound transmission you have to fight, aerial transmission and impact transmission. (I'm not very sure of the English exact term for those).
Impact transmission go through solid support, floor, walls ... The support you printed is a good way to limit those.
Aerial transmission go through ... air 🙂 Regarding aerial transmission, you need an enclosure with a strong mass material. Baffle foam is good to limit reverberation, but unlike what you can usually read is not that efficient to limit aerial transmission. A good choice here would be to use wood and to limit as much as possible air passages (even a small hole can defeat any sound insulation). But since ventilation is needed, some kind of sound trap can be designed to make air go through chicanes to absorb sound energy at each turn, with fan on the inside to help.
When you talk with drummers, the top of the design for a dedicated room is to make a box in a box (each with dense and heavy material), with different thickness to absorb different wavelength, separated with a soft and dense material.
The printer is not that noisy, so some design decisions of such an enclosure may be mitigated, but it's probably possible to build something efficient enough to provide a good sleep quality to your wife 😉
An attention point is that the PSU should probably need to be moved outside of the box. Regarding the Rambo itself, it's questionnable, and the cable management here is a bit tricky.
You can see an exemple of implementing these concept here:
Remember that dividing the noise level by 2 is just removing 3 dB.

Re: Too much fun, banned from overnight printing
@christophe.p thanks for the additional info. The anti vibration feet worked so well that I now have permission to print overnight as it worked so well to reduce noise on the other side. Quite unbelievable.
Out of curiosity I did look into sound baffle and you're right, it doesn't help as a sound barrier at all, only suppressing echo / reverb in the same room. I did find a heavy "sound blanket" that acts as a sound barrier that I could use but at over $100 it's not worth it at this point since the anti-vibration feet worked so well.
Re: Too much fun, banned from overnight printing
Yeah, the dampers do work quite well. The only thing you have to remember is that if you start getting strange calibration issues, it may be that the Y chassis/frame is twisted. The dampers tend to hide that, so you just need to keep it in mind.

P.S. Just had another thing happen to the Mk1 today. saw a pile of black grains under the X motor following a long print. Turns out that the pulley on the X motor spindle had moved forwards and was rubbing the belt.
The grub screws were still quite tight; however the tension on the belt pulling on the pulley caused it to move forward from its original position over time. After loosening the grub screws, I pushed the pulley back about 8mm!

Re: Too much fun, banned from overnight printing
Actually that catched my curiosity, so I digged a bit around the subject.
I used an Android phone apps (sonometre), which is far from being professional but provide some idea of the noise level.
While calibrating, I measured 60 dB, with some spike in the 65~70 dB zone. While printing, it's more on the 55 dB zone.
Just by putting a cork tile below it, I gained 5 dB. Actually, most of the noise are transmitted through the support in silent mode. When using power mode, the nature of the noise seems more aerial (the frame seems to resonate), and add some 5ish dB. Silent mode is really efficient, it seems something like 4~6 dB, which is very important gain, almost 4 time less noisy ! Most of the noise is the fans !
So a simple enclosure with a well designed support should really easily make the noise very low, even in the same room.
Interesting indeed 🙂

Oh, that's good to know, makes sense, thanks.
