Recently, while printing on my Bambu Lab P1S, the filament ran out. The printer paused the print and showed a corresponding notification in the mobile app. This is convenient — you can see what happened. So the question arose whether everything would be okay with the product if I resumed the print after a few hours. For PrintArmy, I always count the amount of plastic on the spool to avoid needing to change the plastic during printing (I don't want to affect the quality of adhesion between layers). I decided to try using the leftover filament from different spools and print something for myself.

In the app, a notification came as expected. After a few hours, I went to change the spool:

The print finished successfully. How did this affect the print quality?

Product strength: in my case, it's hard to say. I couldn't break it at the "joint" location. But I think it depends directly on many factors.

Appearance: if you look closely — you can notice a small line at the pause point. But it's almost imperceptible, especially if the object is not decorative but functional. I don't know how to mark that line in the photo. But I think it's visible.

Overall, it's really cool that the printer maintains the temperature in the chamber and waits for you.
