I’m a noob at 3D printing— I got my Ender3 S1 a little under a month ago. I’ve had great success on multiple prints using mostly default settings, up until last week. I had adhesion problems and was told it was likely my nozzle. I tried a spare nozzle and my next two prints were perfect. Since then I’ve had nothing but messy, blobby unsuccessful prints. More concerning, the prints are sticking to the bed so badly that all I can do is brutally scrape the PLA off. I’ve tried using iso alcohol but it doesn’t make much of a difference. I’ve heard acetone can damage the bed, and I don’t want to make it worse if it’s salvageable.
- Is my bed cover completely ruined?
- What should I do to prevent this in the future?
Thanks in advance. This is my first post on Lemmy and it’s exciting to see how quickly this community is growing!
I can’t quite tell from the photo but I f you aren’t using any glue try using some magigoo or something, seems counterintuitive I know but it helps it release from my experience.
I would also heat your bed up to as high as it will go (I don’t have an wonder but 70 or 80 or something) which will soften the PLA and probably make it easier to get off, that has always helped me in the past.
Looks kinda bad, but once you dial in your settings, you can try printing large part over that area and hope they come off together. Using glue or hairspray can help, but I dont recommend that since its not needed for pla. With thin layer of glue you can probably keep using that bed tho. Better start with too high nozzle-bed distance and decrease in baby steps
This looks like the stock ender 3 S1 bed. If you get the prints off you might actually pull the texture of the metal flex plate. Mine lasted a few days before I had multiple holes.
I got a textured PEI plate and I can’t complain, prints self release when the plate cools and it doesn’t have any defects after almost a year and about 100kg of filament.
Just for reference, what sort of plate did you replace it with? I’m waiting on a Creality glass PEI plate that should be here soon and I’m hoping it will be better. Still not sure how this happened in the first place but from what I read it looks like the print head was too close to the plate and it ground PLA into the bed. I was using the same settings as always and I trammed and levelled before my first print. It seems to have done this every time I tried to print this particular object— Is it possible the actual gcode from Cura could cause this?
Textured PEI flexplate.
Try heating the bed and then scraping with a plastic scraper.
This might be dumb after my first print on the ender 3 I couldn’t get the petg raft totally off the bed it came with. So, I just left it. I figured it was an easy way to adjust the bed height and it printed like a champion after that. Now I have a glass bed and a CR touch which helps a lot with the start
I can’t help you with the quality of the prints, but I’ve found that sticking the bed and print into the freezer for 2-3 mins will help it pop off easily.

I spray hairspray on mine before every run
It’s counterintuitive at first, but using hairspray or 3DLac can really help to prevent the print sticking too much. Or can help it stick more, if needed, just like magic. But weird that it happens to the OP with PLA, usually PETG is the problematic material that sticks too much, not PLA.
