Dolly as stealth as possible

#1

So my goal is to make the ultimate Desktop 3D Printer. That is as quiet as can be. As of right now it is pretty darn quiet. It’s equiped with:

  • TMC2100 (planning to upgrade it down the line to TMC2130, but i need to do some more research on how to get it them to work on my MKS GEN L, any tips?)
  • MK3 X-Carriage with genuine noctua fan
  • Replaced 60mm fan of psu for a 60mm noctua fan
  • Control box equipped with noctua fan 90mm for cooling the stepsticks
  • Rubber feet (that are generally used for subwoovers)
  • Motor dampeners

The only thing that is making a large amount of noise is the part cooling fan (radial fan). Does anyone know what fan i should choose that makes the less noise but does do a relatively good job of cooling the layers? I mainly print PLA so it’s important for me

and use a blower fan @ low speed than you have better and quiet cooling.

I use tmc2100
the tmc 2130 are not worth the work in my opinion.
There is so much bad things written in the datasheet/handbook of the drivers which prusa of course doesn’t tell.

The benefits are to low for the extra work.

dcstep is the only thing which would be nice …

Thanks for replying, The endstop-less homing is pretty cool though. And i already have them in stock so it will be a project for later.

back on topic: The thing you sent is for cooling the cooling-block right? What im talking about is the cooling fan for the layers.

Is there some manufacturer for radial fans that stands out in quiet operations perhaps

I think there a blower fan is the best quietest solution.
But when you buy @ aliexpress you get one with bad bearings.
the air noises are there with every fan / what can make a big difference are the fan shrouds.
I am currently experimenting with some models.
But the main goal for me is to see the noozle which isn’t the case by the prusa model.
I also switched at one printer to a titan extruder.

Alex made a good video about blower fans:

the one which is used by creality is also very quiet. But they are known to be not very long lasting

I’m running tmc2130s on x & y, a 40mm Noctua for the hotend cooler, and another 40mm Noctua for the controller. Loudest things on my Dolly are the radial cooling fan (and the bearings!) I’ve sought a replacement for that fan and have had no such luck. If moorviper has a recommendation for the blower fan, I’d love to hear it, as it would solve both of our problems!

@moorviper - the Noctuas are the quietest things I’ve ever (not) heard! Blowers apparently move more air, but make TONS more noise.

i run the blower fan with only 10% on the hotend heatsink / so you cant hear the fan.
The only thing you hear is a little the noise of the air / but much much quieter than a stock MK2 fan

That is something to try out for sure. I have also ordered a 4010 blower style fan (like the ender3 uses) not sure yet how to mount that one though
