Previously, my life in 3D printing was as relaxed as possible. The printer lived in a separate building, and I could run projects for a whole day - the noise didn't bother anyone. But now my Bambu Lab P1S has moved into the house, and the rules of the game have changed drastically.
Now my day starts not with coffee, but with starting a print (removing the previous print, starting a new one). My new strategy is “Day Printing”. I try to time it so that by midnight the printer has already finished its work and silence reigns in the house.
When "it jams" - it hurts
But theory often diverges from practice. It only takes a little miscalculation with the timing or simply forgetting to start the next part on time, and the night horror begins. You can't turn it off - it's a shame to waste time and plastic. The result? Interrupted sleep accompanied by the sound of stepper motors.
I even conducted a noise test to understand what I'm dealing with:
25 dB - silence when it’s just waiting.
60 dB - standard working hum.
84 dB (and above) - peak sounds that wake me up.
The worst part is that this noise is not monotonous. At certain speeds, it can quietly "purr," but at certain shapes or fills, it produces such sharp sounds that it's really not okay.
The hardware is not to blame
The saddest part is that the printer is in excellent condition. I recently performed a complete maintenance: everything is lubricated, tightened, checked. It's just the nature of high-speed printing in a closed case, which acts like a big guitar, amplifying every movement of the head.
The conclusion of my experiment:
Discipline: If the slicer shows that the print will finish after 00:00 - I simply do not start it, or I reduce the number of parts on the plate.
Early rises: This is the best motivation to wake up on time to manage to print something large.
Cost of error: Bad sleep and feeling broken in the morning.
