Noise & Vibration Dampeners for RepRap Prusa Mendel. Reduces noise, which is produced by the machine during printing, by more then 20dB.


Hello everybody,

I've designed this noise dampeners to reduce the noise and vibration created by my RepRap Prusa Mendel.

The main goles were to:

  • reduce the noise and vibration as much as possible

  • use the least material possible

  • accomodate variation of thickness of the printer feet.

For maximum nose & vibration reduction effect you need to meet following criteria:

Material used: PLA

Fill density: 100%

Please let me know how it worked for you.

Good idea and great job ¡¡ Thanks.

Thank you. all perfectly

Also fit a Delta Rostock :)

They work great! Also fit a Reprap Pro Huxley.

Incredible! I can't hear my printer!

The change in noise is tremendous. I didn't think it will be that big difference. Highly recommended to all prusa owners! Big thumbs up to the author!

Thank you! I didn't realize how much my prusa vibrated before your dampeners.
Now it's so quiet.... :D

This is Awesome! Made them from ABS and it works like a charm. It got my Prusa from electric saw to whisper. This should be featured, even Thingiverse is run by Makerbot.

This is totally awesome. It absolutely works. Reduces the noise and vibration on my desk by heaps.The feeling is like having gone deaf its that good. Thanks for the design!

After a couple of weeks with a heavy prusa on top, the feet have deformed so that they're flatter and less springy. How odd :s (pla)

Same here.DONT_KNOW In order to make it springy it needs to be certain thickness....but luckily for us PLA is bendable under the hot water. ;)

any way to make one that wobbles in 2 directions? I can still hear the x-carriage wobble the table a little, though the y is completely fixed by this.

The reduction in noise is fantastic.

Does just what is says on the tin.

I cant head the axis drives. Now whats your suggestion for that noisey fan!!! :)

I'm happy that the dampeners are working for you. I've noticed that the leg on your print is hollow. You want that solid. As for the fan just peel the sticker in the center off. There is a plastic lock washer, take it off. Pull the blades off, clean the axle, put a little bit of lubricant (WD40, 3in1) on the axle, put it back and fan should be quiet again. ;)

What are you slicing that with?

Slic3r seems to always produce hollow and brittle parts, as there is no solid only outline.

False. Slic3r worked great for my set of these. And it does for just about everything else I print!

Also not everything I print, but every version of these that I printed.

I wasn't stating that slic3r isn't good, but it has some corner cases, for example when tere is almost no infill, it will skip it entirely, while lowering the perimeter helps with the infill it produces lower quality prints.

It would have been interesting to know what tool and setting the author used, to produce better replicates of his version.

Also it could help the author improve his version to make it more printer friendly.

So please less fanboy, more constructive.

Not a fanboy! I was just saying it worked perfectly fine for me printing these and it did have issues with small perimeters before but that has been fixed for most cases with the latest version.

The orign for the STL is located

vertex 1935.496948 1385.301025 25.500000

And it might be better to have set the origin near to zero thus
vertex 26.826904 8.601074 13.000000

This allows the composer in Slic3r for example to mange the object.
On my Huxley print it was also shelled - shoud be interesting to see it in action.

NetFab allowed me to readily fix the posit

My Huxley is placed on top of a box which is clearance above some stairs. This has a tendancy to resonante throught he house. My wife as you might imagine is not happy with the noise of the acoustic resonater created by the box and stairs underneath the printer.

Could save my marriage ;) or
at least allow printing late into the evening.

Just installed mine and they do work quite well. Good job!

I'm amazed at how well these work, I thought they'd snap or not reduce noise much, but they're great. I need to test how difficult they are to break so I know whether to just add the spring design to the next vertices I print.

Let me(us) know how the test went. ;)

Very nice! I printed a set and they're quieter then the foam blocks I was using.

No issues with the "foot" snapping off due to the weight of the machine?

It will withstand weight of the printer no problem. (regular RepRap Prusa Mendel with heated bed, glass
