If you're thinking about using the Diversitech MP4-E E.V.A. Anti-Vibration Pads for your 3D printer, they might actually do the trick.
Even though they're mainly made for industrial stuff like air conditioners and compressors, according to the manufacturer's product description, these pads do a great job at cutting down vibrations with their Extreme Vibration Attenuation material. It's supposed to be better than the usual cork or rubber, and it's also good at standing up to oils and chemicals. They're pretty tough too, since they can handle up to 50 psi, which shows they're built to be sturdy.
From our research, it seems folks have tried these pads under 3D printers and noticed less vibration, which is awesome if you want to minimize noise—especially if your printer shares a surface with others on the same table. This could be just what you need for a quieter, more stable printing setup.
A nice perk is that these pads don't have a strong odor, unlike some other options that might make your space smell for a while. Any smell they do have fades pretty quickly, according to some folks who’ve used them.
That being said, the results can vary. Some found that when used with different things, like a ceiling fan, they were only about 80% effective. So, it might depend on exactly what you're using them for and how intense the vibrations are.
Overall, these pads are well-regarded for being reliable and a good deal. You get a pack of four, which can help make your setup more stable and might even help your equipment last longer by cutting down on vibrations.
Even though they're aimed at industrial uses, if they seem to fit your needs, the Diversitech MP4-E pads could be worth a shot to keep your 3D printer running smoothly.
