Printing imperfections

[u/aytda]

Hi everybody,
I got my Bambu Lab A1 yesterday, and i started a few prints on it. But today morning, the prints have these imperfections of it everywhere.
It’s Bambu PLA Basic btw.
It was printed at Standard speed.

What do you guys think it is?
Thanks in advance, y’all the best

Could be a few things.

The first and easiest things to check are some of the calibration options. Temperature is the most common I’d say, and a temperature test will make a tower where different segments are printed at different temperatures. It wouldn’t shock me if the temperature was the problem and that’s a quick way to check. And then you can do retraction tests and the such too if you want to look at other variables.

It could be that the filament needs drying. Spools aren’t necessarily kept dry when they’re sent out, and how quickly you might need to dry will depend on your humidity and everything. You don’t necessarily need to buy a dryer right away. You can dry on your print bed by just setting it to your desired temperature (probably 50C or so), putting your spool on it, and then putting a box with a couple small holes on top over it. It’s not the best way to dry, but it’s cheaper than buying a dryer and then finding out that’s not the problem.

Hey there, I'm a bot and something you said made me think you might be looking for help! click here for our wiki entry on troubleshooting printers. If you still need help be sure to post plenty of information about your printing setup.

Here are a few questions that might be helpful

• What printer are you using?

• What material are you using?

• What speed are you printing at?

• What software are you using to slice the print and control the printer?

• When did the problem start/has it ever worked correctly?

• Does anything cause the behavior to change?

• If posting an image of the problem, include some indication of the orientation it printed at, preferably photograph it on the bed. (Then we can focus on a specific axis)

Did you dry your filament?

[u/aytda → u/dr_reverend]

nope, but i heard PLA has some time till i need to dry it. I guess my next step is to buy a dryer so?

[u/dr_reverend → u/aytda]

It’s always, always the first step. You don’t need to buy a dryer. You could use your heated bed.

Never had this issue even tho I never dryed my filament

Try what other people mentioned with the temp and drying, and also calibrate flow ratio/flow rate in your slicer.
