Sound Chamber for MK3
Hi,
I'm currently printing a lot over night, due to long print times. Today my roommate told me that he often hears the printer in the night.
I don't want to run the prints in steahlth mode because I dont want to lose the crash detection.
So my question is if anybody has build a chamber to silence the printer maybe with acoustic foam or something similar. I have the ikea enclosure for printing ABS. So my idea was to just get rid of the acrylic glas (on the sides and in the back) an put a wooden plate from the outside. Then atach acoustic foam in the inside so I wouldn't lose space in the inside. Another thing i will try is to change the table were the printer stands on. I guess the hollow "wood" table from ikea amplifies the sound.
What do you think could it get to hot in there with the foam?

Have you considered using a solid slab of some sort? The idea is that adding mass decreases the printer vibration which reduces noise. You can then isolate that increased mass from the supporting table surface using isolating pads (e.g. Sorbothane).
Stefan of CNC Kitchen has videos on this topic that are well worth watching:
Key points are:
-
The trick to reducing printer mechanical noise is to increase mass.
-
Mounting the printer on a heavy surface such as a 17x17 inch paver stone adds mass.
-
Accoustically coupling the printer to the mass maximizes the vibration dampening effect.Do not isolate the printer from the base. Felt non-isolating feet work well.
-
De-couple the printer mass from the resonating surfaces. Isolating foam or Sorbothane feet work well to keep any remaining vibration from being transmitted into the flat supporting surfaces.
I've got some notes here.

My current setup uses an anti-fatigue mat to decouple the printer and paver from the drum of a folding table they rest on and works quite well.

Hi,
I've got in mind to use a temporal enclosure for printing that might help also to isolate the sound. I plan to use the puzzle foam tiles used for gymnastics. The whole printer looks that might fit inside
I think the weight approach will help also.

I think you used the wrong word there. I can't tell where you are from (you haven't put that in your profile), so I'm not sure if it was an accident or if it is likely that English isn't your first language... 😉
I think you meant to say that you are planning on using "a temporary enclosure", meaning that it is not a permanent enclosure. A temporal enclosure implies that you've cracked the physics and engineering to be able to create a volume of space where time flows at a different rate. That would presumably mean that you can reduce printing times by increasing the flow of time within the enclosure so you could get your print done before your roommate goes to bed.
If you really did mean a "temporal" enclosure, quick get that thing patented. The industrial world would make you rich beyond your belief if they can increase their production volume simply by putting their manufacturing processes inside your temporal enclosures. 🤣

Replace the felt pads on the printer feet with 3M hemisphere anti vibration feet sj 5027 16mm diameter. Then put the printer onto a slab as already recommended. You will see a big reduction in noise.
The 3d printed anti vibration feet do a good job of reducing noise but can cause instability in the printer. The 3M feet willl give a good noise reduction without causing any instability in the printer.

Made my day. 🤣

Wouldn't it be better to put the anti vibration feet under the slab?, as you actually want the printer to be close coupled to the slab hence increasing it's mass considerably, which will reduce movement caused by the print head and bed changing direction rapidly. This will reduce ringing in the prints considerably, and the anti vibration feet will decouple the whole thing from the table or whatever it is standing on.
Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.

Very bold claim to say it will reduce ringing considerably. Do you have any evidence of this?
All I can tell you is I have 3M anti vibration feet on the printer and then mine is on a substantial steel base. It is very much quieter than standard with great print quality and is perfectly stable.
RE: Sound Chamber for MK3
On my printer I had it on squishy feet whilst trying to quieten it and I had visible ringing artefacts and the whole thing was wobbly, replaced the feet with rigid feet with felt pads and the ringing artefacts noticeably reduced, this was when printing at up to 200% speed, at 100% it made no appreciable difference as the printer does not have much ringing at this speed to be honest, start pushing the speed though!.
This was both in the x and y planes, the squishy feet are now under the granite chopping board which has made a huge difference to transmitted noise, basically, I don't have any anymore, you used to be able to hear the printer through the floor downstairs. I also cut the feet down as they were a little too wobbly.

@chocki
I wonder if bolting the printer to the slab would improve it further.
I don't know the shore rating of the 3M feet but they do not allow any discernible movement of the printer or degrade the print quality.

Correct me if I'm wrong but I don't see in the video of it improving ringing from the standard setup.
