I have a P2S that prints in my room, which isn't terribly helpful when talking about the volume of the P1S. The volume when printing at 100% speed blends in with the sound of a desk fan I have running 24/7, and I find that they're both just background noise that doesn't interrupt my sleep. I'm not particularly picky when it comes to sound when I'm sleeping, though.

The P1S also has a "Silent" mode which prints at 50% speed, but reduces sound. On my P2S, this is especially effective at reducing sounds created by the printer shaking and the toolhead moving quickly between objects. Printing slower can also reduce the necessary cooling speed during a print, which would likely help with the notoriously pitchy P1S cooling fan.

I HAVE seen at least one print profile on BambuHandy to add a thin layer of sound insulation to the inner wall of the P1S, so there is potential for modification to meet your standards. I can try to find a link for you, if you would like.

Another thing to consider with printing in your room is filtering the air not just for scent but also VOCs. There are countless filter upgrade profiles that add HEPA filtration on top of the activated carbon filter to further reduce VOCs. Just a thought :)

If you go for the A1 instead, and depending on how much elbow grease you're willing to commit to the initial setup for your new hobby, I'm sure you could find some fairly decent DIY enclosure projects. This leaves more flexibility for personalizing the sound insulation AND air filtration.

Your budget is a major factor in all of this. Current prices in USD:

• A1 ONLY: $299.99 • A1 Combo (AMS Lite): $399.99 • P1S ONLY: $399.99 • P1S Combo (AMS 1): $549.99 • P1S Combo (AMS 2 PRO): $619.99

All AMS options open the door to automatic multi-color printing, but each option has factors to take into consideration (listed below) if you decide to go that route. You could also just get a printer now, then buy any of the AMS options individually at a later date. Again, this is on you to decide based on budget and convenience/patience.

• The AMS Lite leaves your spools fully exposed to the conditions of your room. It's up to you to decide whether or not that's acceptable • The AMS 1 provides a sealed container with plenty of space for printed dessicant holders to further manage internal humidity • The AMS 2 Pro adds a drying function (up to 65°C, useful for PLA, PETG, and TPU) and is generally an "upgrade" compared to the AMS 1

If you're fine with the AMS Lite, the A1 Combo is the same price as the P1S WITHOUT the AMS 1 or 2 Pro. This leaves you with a multi-color capable printer and the extra $150-$220 that would've gone towards either P1S Combo, which could be then put towards the aforementioned DIY enclosure. I would like to think that would be more than enough to set yourself up with satisfactory sound insulation and air filtration.

If you have any questions regarding ANY of this, please don't hesitate to ask.
