Vibration question

Hi all,

How sensitive is the print process to external vibration? Do I stop the kids running around the room while printing? I’ve installed the printer on a pretty firm table but it will vibrate slightly when the « little terrorists » start activities 😏

I believe even such natural disaster like kids will not corrupt your print when running around. On contrary, I have installed vibration dampers on the printer legs to decrease vibration coming from printer. During a day, no issue. During a night, not so nice. Vibration dampers will protect your sleep from printer and most probably also your printer from running kids and other wild animals 😉

You're coming at this from the reverse angle from most users. Reducing printer vibration noise is the usual concern. However, most of the same principles still apply. Stefan of CNC Kitchen has YouTube videos on vibration that are well worth watching:

Key points are:

  • The trick to reducing printer mechanical noise is to increase mass.
  • Mounting the printer on a heavy surface such as a 17x17 inch paver stone adds mass.
  • Acoustically coupling the printer to the mass maximizes the vibration dampening effect.Do not isolate the printer from the base. Felt non-isolating feet work well.
  • De-couple the printer mass from the resonating surfaces. Isolating foam or Sorbothane feet work well to keep any remaining vibration from being transmitted into the flat supporting surfaces.

If you're mostly worried about isolating the printer from external vibration, decoupling the printer from the supporting surface is a good place to start. If you don't want to go with a heavy base, there are 3D printable feet available on Thingiverse that will accept Sorbothane pads to isolate the printer. Read the cautionary notes about rubber feet on furniture. Put a pad under it if the supporting surface finish is important to you.

Move the printer to the DMZ, before something bad happens.

 

Good Luck
