Appreciate the suggestion about the belts. I'm up for replacing them, though the sounds that are being emanated sound more like a squeaky or a metal on plastic sound. It's hard to imagine belts alone making the sound as they do still feel pretty soft and rubbery, not hard in any way.

We have had our Ultimaker 3 for several years and have followed the maintenance guide as best as possible (lubricating rods and lead screw, checking belt tension, etc). For the last several months, the printer has become quite noisy and it seems to be a mechanical noise, rather than the stepper or electronic drive noise. It's hard to figure out if we have missed a lubrication point or something similar? Hoping that someone with more experience can listen/watch the attached zipped video and perhaps notice something familiar as far as the sound and share how we might address? Thank you so much. -Rob Ultimaker_Noise.zip

Unfortunately, micro-plastics, which are emitted during printing, are so small that they pass right through even a HEPA filter. This is of concern as its not clear what the long term affects are of this on humans. Best practices would have you print in a separate room or to introduce ventilation. We recently put a full enclosure on our Ultimaker 3 and ducted a very low cfm fan to blow the air outside during printing. Kind of like a dust collection system that you might see in a wood shop. https://www.fabbaloo.com/blog/2017/9/21/guess-what-standard-hepa-filters-may-not-solve-3d-printer-emissions https://blog.gotopac.com/2018/10/09/carbon-hepa-filters-for-toxic-3d-printing-fumes-particles-odors/ https://cen.acs.org/materials/3-d-printing/3-D-printer-emissions-raise/96/i13
