Im a new beginner in 3d printing and as soon as I printed the first object I faced the same issue which is shown in the image . I still didn’t figure it out yet

Dryed the filament before use? Never use filament right out of the bag. It can be wet resulting in interesting failures. Even in a vaccum bag.
Actually no I didn’t dryed it. I’ll try to dry now before I print anything. Do I need a device to do the dry it or there are different ways to do it.
Is that the support filament by chance?
My thoughts, too. Bambu sends a roll of white support filament w/AMS combos
Okay, here’s another newbie.
How should it be possible to have moisty filament in a sealed bag with silica gel inside?
Yes, I take care, to keep moisture out of my AMS. I printed additional silica gel boxes for it right after my first benchy.
However I never expected that I have to dry filament first, when it comes from the shipping bag. I did not. None of my last prints (about 100hrs from four different spools) failed. Was this just luck?
Thank you
I’ve asked a similar question in the past, I wanted to know if folks are drying EVERY roll or just waiting for failure then drying? Seems the answers are all over the place, but my take is most are printing with filament right out of the sealed bag and if they experience an issue, the first thought is to dry the filament.
Except for a filament like TPU, seems the suggestions are to dry that one first as it is one of the most sensitive to moisture.
Also, now that winter is approaching, not sure about your locations, but where I live the humidity is way down. On a floor in my house where I would normally see 60% humidity, it is now 34%. What that means is I’m not as diligent about storing every roll in dry storage, I leave much of it out. Also, during the summer , if time permitted and it was a long print I might handle drying a bit different than my typical wait for failure.
If time permitted, I would dry the colors involved in the print regardless of failure.
Ah, thank you for taking the time to explain.
I think I will as well continue not to dry spools that where just delivered.
I had heard about that moisture problem and therefore I already bought Ikea boxes as dry storage for a hand full off spools to start.
So new spools will be stored well and if they really had moisture before, they hopefully will be cured in the dry boxes over the time. I am not printing for business, so some spools will stay long in their boxes.
The little bags of silica gel are really just to keep moisture out of the air. Filament has the ability to also pull water out of the air and retain it inside itself. Putting silica gel with it will prevent additional water from the air from being absorbed into the filament, but it doesn’t do anything to get the current water out of the filament. That’s why you heat it low and slow, just enough to let the water evaporate out.
Now, do you need to do this for every new roll? Some would say yes, the longer you’ve been in the 3D printing game, the more you’ve seen rolls come from factories, vacuum sealed with the little packets, and are still heavy with water. As an experiment, you can get a good scale and weigh your filament roll, then dry it for a few hours and weigh it again. That’s just the loss of water (unless you accidentally melted the whole thing…!)
Personally, these days I don’t dry most filaments, especially PLA varieties. I don’t run into any issues, but I will store them in dryboxes once open with the silica packets. For the rare times I print something else, I usually will dry it first. The point is, you don’t know the conditions in the factory, or how humid it was when they extruded and rolled up your particular reel of filament. If you want to remove potential issues, dry first. Otherwise, dry it once you hit an error or two with that roll.
