Silencing a 3D Printer - Stepper Dampers

26. June 2014 10:26 by Sean | 1 Comments

I recently built a new 3D printer, my second after the MendelMax I’ve been running for a few years now. I went with a Kossel Mini, it’s an amazing little machine and since it’s designed to print only in PLA it can sit right next to me on the desk without filling the room with nasty ABS fumes.

That’s all well and good but if you’ve ever sat next to a 3D printer you know that they can be pretty noisy. Especially one as fast as the Kossel Mini, it can be really distractingly loud. After searching around for solutions I came across some whispers of a product on a 3D printing forum about stepper dampers and just how much of an amazing difference they made. It seems there is still very little awareness of these little gems in the community but the few that have tried them are adamant that it’s the best upgrade they’ve ever done!

As you can see they are made from two metal elements joined by a rubber gasket between them. One side bolts to the motor and the other to your printer as normal, this leads to the motor to be fully isolated from the printer. The rubber is formulated to dampen the specific frequencies the motors produce and is very stiff, with the amount a printers belts are tightened there is no danger of problems caused by the rubber flexing and moving.

So… do they work? Well as with the few others than have tried them I can say with certainty that they are simply jaw-droppingly amazing! I can now sit right next to the printer and completely forget it is even running. Check out this video I made to show the difference.

I now couldn’t live without these!

 

As you can see the difference is around 17dB! Nothing more to be said, they really are that good!
