EVA Anti-Vibration Pads for Noise Reduction
It's no secret that 3D printers can be loud, and the RepRap Prusa i3 that I use is no exception. Mine sits next to where I work all day, so I was tweaking it a bit to make it quieter the other day. I noticed that if I picked up the printer even a little, it significantly reduced the amount of noise it generated (and messed up my print, so don't do that). I quickly realized that the vibrations created by the stepper motors must be translating into the desk.

I had felt pads on the printer to prevent it from scratching the desk, but they didn't reduce the printer noise in any significant way, so I set about solving this little noise problem. I found a lot of people recommending products like foam, rubber and cork for their 3D printers, but my research led me to a very inexpensive and effective solution - DiversiTech EVA anti-vibration pads. As of this writing, they're $2.39 for a 2" x 2" pad, and $2.67 for a 4" x 4" pad. They cut easily with a box knife, so I just ordered four of the 4" pads and cut them as I needed. They're fairly thick, so I wouldn't recommend cutting them any smaller than 2".

 

These pads have made a tremendous difference in the sound level of my 3D printer - I can no longer hear it even one room away, or on the floor above or below. They're also strong enough to place under home theater equipment or shop equipment like an air compressor. For the cost and time involved, I consider this one of the best upgrades I've made to the printer in a long time.
