I am looking for methods to reduce the amount of noise produced by my CR-10. I have the printer in my downstairs study and if I'm doing a long print job, you can hear it upstairs in my son's bedroom and I don't want it keep him awake.

I've seen there are noise reduction feet available on Thingiverse but apparently these can result quite significant vibrations of the printer itself, which could mess up the print.

I've also seen one guy using a paving block but I'm not sure how effective that would be and also don't think my cheap Ikea desk would cope very well with having a concrete block put on it.

I was wondering about trying an off-cut of carpet. Has anyone tried this or have any other suggestions?

I do know about your budget, but I would suggest to buy a silent 3d printer like Prusa i3 mk3 which is about $1k. If you decide to tinker your printer instead than take a look on other possibilities:

Trinamic drivers

Most of the noise is created in motors.

Definitely switch to Trinamic stepper motor drivers. I have upgraded from Prusa i3 mk2 to mk3 last weekend and the noise reduction is significant, my estimate is 80-90%.

Take a look on this awesome blog post and video from Thomas Salanderer about the driver. Other good post is on instructables.

I would not suggest soldering unless you are a skilled hacker. Better option is switch to different board.

Prusa i3 mk3 is using Einsy Rambo 1.1 for $120: https://ultimachine.com/products/einsy-rambo-1-1 But there you have to switch to 24V Power Supply Unit and you have to also switch to 24V heated bed.

Another solution is to use RAMPS and buy trinamic drivers separate (RAMPS doesn't solder drivers on the board).

Pad

Use a concrete paver as described in this youtube CNC Kitchen channel. It reduces noise by 20dB (not if you use trinamic drivers).

Enclosure

An enclosure should also help to reduce noise.

Dampers

Dampers help you reduce noise. There are two types of dampers:

Personally for vibration reduction I use a large mouse pad I cut to size, but I'd imagine the carpet would perform just fine. I would also recommend enclosing your printer (this had the most profound effect for me) and upgrading your stepper drivers.

I use a paving block with rubber feet underneath it on the floor. It is very effective: The 3D printer is sitting right beside a door, and you can't hear it printing from the other side of the door.

The low-frequency sounds are definitely absorbed by the paving block. What you can hear now are only the hissing sounds, when the extruder glides along the rods.

I wouldn't put the paving block on a table, though, or anything elevated, since that will only magnify the lever effect of the table legs and exacerbate vibrations.

Change DRV8825 / A49nn series on board stepper driver with Trinamics TM2100 ( in silentChop mode) will make your step motors almost silent. They are outstanding.

But there are couple of disadvantages:

  • There is chance of losing steps in slientChop (Would not effect print quality in my experience)
  • TMC2100 is 5-6x times more expensive than DRV8825
  • Require soldering and electronic knowledge
  • TMC2100 runs hotter

I have an Anet A8 and these vibration dampers do a great job:

I had a similar problem, the neighbour started to complain. I solved the problem by putting scourers under the table where my printer was placed on top of.

They are mildly effective, but very cheap. They were 7 cents a piece at my local supermarket.

If you hear it from a floor to the other the only thing to change is the base of the printer. Nothing else matters.

CNC Kitchen performed measurements especially to avoid noise being transferred to other rooms, the result is that placing the printer not on elastic feet, but on a single slab of concrete which is placed on top of foam is the best solution and reduces the noise significantly.
