Wet filament can do that. Even new filament can be wet some times, especially with rarer colors that sit around in storage for much longer.
Oh I didn’t even consider this I’ma try this first
This filament has been sitting out for a while so this seems very possible
Can look up tables of temperatures and times for using an oven to dry various filaments. Putting in sealed container with desiccant could work but will take much longer
Toss it in a box with dessicant packs for a few days. If it’s not flexible and breaks easily, it’s too moist.

Dry that shit always, super easy to eliminate that variable
Check for clogs in the nozzle And check your extrusion motor, that might need a clean
Filament also might need to be dried, if you hear crackling as it comes out of the nozzle it’s most likely too moist
Looks to me like your temperature is too high and you need to increase your retraction distance.
Also may help to have improved blower (fan replacement/more focused outlet)
I am absolutely gonna do some test for this
As others have mentioned:
Stick it in the oven for 2+ hours on minimal settings. If you have a fan in the oven, even better.edit: use the printer bed, see comments belowNothing wrong with Ender 3, if you thinker enough, you can get results as good as any other printer. But it may require tinkering. The model that you’re printing is difficult with FDM printers of any kind. It has thin, delicate parts with steep overhangs. It can look better, but it’s gonna be hard to achieve. Resin printers are definitely a better choice for this, but you use what you have.
Gotta be careful with ovens.
First they have a huge gradient and it may not be 60c in there even if the oven says it is. If you must use an oven, the best is to set it to bread “proof”- this setting is used to let dough rise and usually isn’t all that hot. (Though…. It could be. It’s inconsistent sometime,)
Remember, glass transition is usually about half the melting temp, and you want to be about 2/3s that at the highest. If you go past it, you might get sintering- the filament sticks to itself.
Personally, a cheap food dehydrator is going to do the trick. Alternatively, a tub with moisture absorbing beads bulked up in the bottom and few days or a week or two should do the trick gently. (You can buy big ass jugs of the beads at big box hardware stores or Amazon. Hell you can get 55 gallon drums of them if you really wanted to…)
True, I’ve seen many molten rolls of filament because of overly warm ovens. Make sure it doesn’t go over 60C and you’re good. Mine is good, has a little overshoot when heating up, but if you let it warm up first and then put the filament, it generally stays very close to 60C. I havent had problems. Other ovens - be careful. Food dehydrator is better, but if you don’t have it, you may as well buy an actual filament dryer. Desicant beads didn’t work for me. They do the trick of maintaining the dryness, but if you have ANY built up moisture in your filament, the beads won’t do much.
Throw your ender away and buy a good printer.
Every single thread like this is an ender.
They’re shit.
Man I’m broke and I’ve had this thing for years Fuckin love it
You know that’s generally not helpful, right?
Like, okay. Enders are not the best printers. It’s what they have. Most of us can’t just go out and get a printer just because it doesn’t meet your standards.
People should have realistic expectations, but Enders aren’t incapable of okay-prints, and with a lot of love, some awesome prints.
This is especially not helpful since it’s probably the filament needing to be dried and temp adjustments for the plastic.
Well my fdm wont print anything this size so yours is a lot better
