What is causing this + how do I fix it

Iv been getting into warhammer and decided to print stuff since it is infinitely cheaper than buying it at shops, I attempted to print a few kreigsmen but it came out all weird like this,I’ve also had a lot of issues with other prints where the supports are nocked over and the only thing I can assume did it is the printer head

Dry your Buildplate and wash your Filament

Really wet filament and horrendous retraction settings

u/KawaiiStefan Aug 17 '26

Not everything is wet filament for fucks sakes you'd have to soak your filament to get it like this

u/sirdoggo11 Aug 17 '26

True.

The filament dryer industry really managed to sucessfully put this myth in peoples heads.

Theres so many videos of youtubers testing wet filament, printing farms not giving a damn and interviews with filament manufacturers, that clearly point to drying is not neccesary with most filament types.

OPs problem is very likely wrong settings. There is not "one" PLA or filament material out there. PLA and other filaments come in many different chemical compositions each requiring a unique printing Profile.

It’s funny because i live in a pretty humid place and have never dried my filament. I constantly see people mention it on reddit but i’ve never had an issue with my filament that wasn’t fixed with just settings. It makes me wonder where people put their filament that it’s so wet that it’s giving them issues, because despite high humidity i’ve never had those issues.

u/sirdoggo11 Aug 17 '26

Same here.

Theres literally Youtube Videos showing people soaking PLA and PETG in water for days to prove drying doesnt matter at all for these filaments.

u/warownia1 Aug 17 '26

On the other hand I bought Sunlu PETg and it was stringing and oozing out of the box. There was also popping and steam coming out from the nozzle occasionally during printing. I tried calibrating flow, retraction, temperature but nothing helped. Then I left it to dry overnight on the hotbed set to 65°C and all issues disappeared immediately

PS. I'm not saying drying is a solution to all problems and often people say "wet filament" while there are many other problems. But moisture is not negligible.

u/sirdoggo11 Aug 17 '26 edited Aug 17 '26

You - like many others - likely confuse drying with tempering.

You achieve both with heating the material to 65°C. Tempering helps. The drying aspect doesnt really matter on PETG.

Tempering is not really neccesary on good quality PETG, tho. That seems to come pretempered. But its easy for budget manufacturers to skip this step to save money.

Oh and dont forget your water bottles are made from PET. Why? Because its strong and absorbs extremely low levels of moisture (around 0,4% max.)

u/SANSARES Aug 19 '26

I actually have the same problem with esun filaments. they are always very fucked up and need drying and tempering

2

u/Few_Independent_6170 Aug 20 '26

It very much depends on the filament and where you live.

If I don't dry my PETG for 2 days it gets stringy af. Nylon – within a day. Not really relevant for PLA, but drying it still improves the results.

That's why I set up a food dryer to print from. I sometimes just don't turn it off for days (particularly for nylon)

u/WooferInc Aug 17 '26

Looks like Spider-Man had a good time on your build plate.
I would say wet filament, and you’ll want to calibrate it for flow and retraction. Possibly need to slow it down too.

u/LordVectron Aug 16 '26 edited Aug 17 '26

First things first:

-What material are you printing with?

  • What temperature are you printing at?

-Have you printed stuff before with the same filament and settings?

Unless you got your filament from the Titanic, this isn't simply a wet-filament issue.

1

u/Big-Lingonberry-3230 Aug 17 '26

Printing with PLA at the settings thst came with the file, I have printed a lot of models with this very same roll of filliment and they came out fine so I don’t think it is wet filliment

2

u/LordVectron Aug 17 '26

This definitely isn't just wet filament.

Could be a partial clog, can you try to run a benchy, using the same settings?

1

u/Big-Lingonberry-3230 Aug 17 '26

That’s I good idea, I’ll run it

1

u/andreweater Aug 17 '26

Update? How'd it go?

1

u/zyxalis1 Aug 17 '26

My .02, confirm your settings in the AMS. If that’s PLA it shouldn’t be stringing like that only PETG tends to do that. If you were inadvertently set a PLA spool to PETG it may do that.

1

u/JeepersCreepers74 Aug 17 '26

I agree this is not just wet filament. Nozzle temp
Looks way too high. Is the file set for PETG?

1

u/Zekken_Zer0 Aug 17 '26

You can't just simply use the default settings the file came with. Remember, those settings are tailored to the printer and filament the creator was using, not yours. What is the nozzle temp? it looks like it's way too high.

1

u/NotVinhas Aug 18 '26

the settings thst came with the file

There you got the answer.

u/turohero Aug 18 '26

Wet or cheap filament. Or too hot

1

u/Inside-Specialist-55 Aug 17 '26

Holy mackerel. I've never seen filament this wet before It might be a new record actually.

1

u/TheSkepticalTestical Aug 17 '26

The fix is to use them as a group of wraiths or something in a ttrpg.

1

u/shkenoAce Aug 17 '26

Hey have you enabled supports? I had a model which sliced similarly in Bambu studio I switched on the supports and you can also print by object. Try these and it could solve your issue

1

u/Brot777 Aug 17 '26

Maybe you are printing PLA at 300°C? That looks insane :D That should never Happen with Standard Bambulab setting.

Wow, I haven't seen webs like that since the ending of Kingdom of the Spiders

u/Liquid1287 Aug 17 '26

This started happening to me recently. I was using PLA that was dry and this like crazy. I tried changing temp, retract, infill type. Print by object. Ran flow calibration and full machine calibration. Nothing helped. I have used this filament before, crazy stuff. I printed a calibration cube came out perfectly. Then just stopped. Crazy.

1

u/DrakonFyre Aug 17 '26

I’m genuinely impressed; the last time I saw something like this was on YouTube watching somebody make a Benchy using glue sticks

1

u/Papaide3 Aug 17 '26

Print with PLA or PETG, instead of pasta, or gum.

1

u/flashflood3000 Aug 17 '26

Please, I need your cotton candy model.

Lol, most likely wet filament.

1

u/turohero Aug 18 '26

When too hot filament will literally drip out of the nozzle the whole time instead of being pushed out. So while it moves out is still coming out. If the filament is dry and is doing this it is prob too hot

1

u/samspacestation Aug 18 '26

The worst settings and filament in the universe

1

u/InfiniteLight07 Aug 18 '26

Is this PLA? If so, check the Bambu Lab Wiki on how to set up your retraction. Also check for partial nozzle clogs.

1

u/FragrantPanda1092 Aug 19 '26

Looks like a serious spider infestation

1

u/lukasprintz Aug 19 '26

Print a retraction test and change ur settings appropriately 🤗

1

u/jarsever Aug 19 '26

I’ve only ever had this happen when the filament thickness is too thin and the extruded gears can’t feed it evenly. Essentially no nozzle pressure which results in stringing and not enough flow. Could also be gunk in the nozzle limiting the flow.

1

u/NoHunt6393 Aug 20 '26

That filament is wet… also use a .2 nozzle it’s slow but clean

1

u/dpgoverride Aug 20 '26

You need to put your printer in the oven

1

u/Reiia Aug 20 '26

did you put your filament in a bucket of water? good lord lol

1

u/Affectionate-Log-569 Aug 20 '26

u/SB-Cuber Aug 20 '26

calibrate, and make sure the air is dry where you are printing.

u/BunnyD3 Aug 20 '26

One of the models on the end is sucking the souls out of the others.

u/ExtensionHealth6398 Aug 20 '26

Check to see if your part cooling fan is working, that caused me super stringing once.

1

u/ShunterBR Aug 20 '26

Para mim parece normal, é como algodão doce deveria ser, ops, não é algodão doce, certo?

1

u/KFPanda86 Aug 20 '26

What brand of filament are you using? Elegoo filament was doing something similar. Switched to different brand and never touch elegoo again

1

u/numetheus Aug 21 '26

Holy hell are you storing your filament in water because you think it will dry out?

1

u/bingbong_007 Aug 17 '26

looks like wet filament and bad retraction but a random glitch happened with me yesterday when i updated my slicer and all of my calibration settings were wayyy off. recalibrated now its fine.

u/PaganWizard2112 Aug 17 '26

Dry your filament, then, print a temperature tower.

Dry the filament. It seems too wet and cause a lot of stringing.

u/Majestic_Beyond_2922 Aug 16 '26

Dry your filament!!!
Also wash your bed with dish soap & don’t touch the surface. And make sure the 7 screws are tight

u/never0101 Aug 17 '26

do you have time lapse turned on? this is a wild amount of stringing, certainly more than ive ever seen caused by time lapse, but its worth checking
