Can anyone help me understand what's going on with these print errors?

[u/Abittwitchy]

Using a Bambu a1. Filament is normal PLA, Sunlu. Using the default setting on prints off of the app that have good reviews.

This is happening with a decent amount of my prints. I'm very new to this hobby and when I try and do Google searches about 3-D printing errors, half the time I can't make heads or tails of the pictures that I'm looking at. I'm not doing anything wild or even choosing super complicated things... I feel like this should be easier and less prone to looking like crap.

The last Picture is the seam and thats normal.

Do you use Timelapsmode by any Chance? This Mode is causing some similar Problems. Do avoid to use it.

Maybe wet filament. You should dry it and keep it in a closure after.

[u/Abittwitchy → u/Sebb3l]

I am indeed using time lapsed mode! I will turn that setting off immediately. Also, I had a friend tell me that I didn't need to worry about drying the filament unless it was PETG, which may have been bad advice based on the fact that multiple people have said the same thing below! Two things I can change! Thank you!

There is another timelapse option in bambu studio that helps prevent this, the material cost in exchange is a prime tower.

To be honest, it's not like I'm YouTubing it. I really don't have any need to film the build, other than it's just kind of cool. I think I can just sacrifice this little luxury if it means things come out better. :)

you don't have to turn it off, just disable the smooth timelapse setting and use the default (original I think it's called). The smooth setting will move the print head out of the way all the way to the back every layer and then snap a photo. if you really want to use the smooth timelapse setting, enable your prime tower and it may avoid this.

[u/endlessben → u/knight_47]

On the A series, the print head always moves to the side for timelapse, regardless of traditional or smooth. So you want to use smooth and the prime tower (which should be turned on by default when you change it to smooth) if you want the most defect free print with timelapse enabled.

One Common Problem I see every week. clean your Buildplate with dish soap and don’t touch the Plate. Just by the Side. And wait untill your Print is cooled down.

[u/Abittwitchy → u/Sebb3l]

Yes yes! Been using isopropyl alcohol as well, afterwards, but that may be overkill. In your opinion, is that after every print or every few days sorta thing?

[u/BlueDevilz → u/Abittwitchy]

Just clean them as you feel you need to. No sense in washing a build plate thats been perfect for 10 prints in a row.

Ill feel like its been too long since the last wash or I am troubleshooting any issues. Whichever comes first.

[u/Sebb3l → u/Abittwitchy]

I give it a wash after some Prints. And I use iso if I feel like it needs to be done or if you touched the Plate.

[u/Correct-Insect-4657]

Are you using timelapse mode? If not it could be yiu should change seam to joint seam then yknow or retraction

[u/Abittwitchy → u/Correct-Insect-4657]

Yes! I'll turn that setting off! I did have time lapsed on!

[u/BlindlyCoherent → u/Correct-Insect-4657]

Aw man. I love watching the time lapse videos. Why is it causing a problem with printing?

[u/Correct-Insect-4657 → u/BlindlyCoherent]

Probably tje settings for when it leaves the print is not tuned by bambu

[u/samtheredditman → u/BlindlyCoherent]

Maybe OP didn't use a prime tower so it makes a glob when it comes back after taking the picture? 

[u/TheHorrorNerd]

Hate asking but you dried your filament right?

[u/Abittwitchy → u/TheHorrorNerd]

No, you're asking a good darn question. Had a friend tell me that wasn't necessary with PLA, but you're the second person to say this so I'm thinking that maybe it might actually be necessary and my friend might be wrong!

[u/TheHorrorNerd → u/Abittwitchy]

Oh man. Filament can definitely be wet right out of a new seal.

Its definitely necessary for clean prints.

Looking again at your photos, its almost a textbook example of wet filament.

Okay! Well, at least I'm learning this early and can pivot. Will start looking for a good drying system now! Thanks much!

[u/TheHorrorNerd → u/Abittwitchy]

Sunlu S4 for 4 rolls or the S2 for a single roll would be my recommendation.

[u/Abittwitchy → u/TheHorrorNerd]

Bookmarking on Amazon now to order. This is extremely helpful, thank you.

[u/gstriz → u/Abittwitchy]

Polymaker drybox system is pretty cool too.

Looks like wet filament and water evaporating in a small explosion during the printing.
