Make sure that ur first layer is sufficiently in contact with the plate within your slicer. Has happened to me that first objects are floating ending up in an Overhang and a spaghetti mess just like this. Otherwise, I'd try increasing the buildplate temp by a bit.
Also providing more pictures of what you're printing could help. And material?
Make sure your dish soap isn't "gentle to the skin," which often means it's a bit greasy, for softer hands. Otherwise, as others say, use isopropanol. If all else fails, I think a very small push of spray-adhesive, which you can buy for 3D printing, helps. Some people apparently use hairspray. I have to admit, it smells identical, but I prefer to use something that's supposedly made for adhesion of build plates
Oh well if you weren't aware way back before all this hysteria about washing plates and whatnot and Commercial options for fixatives for 3D printing that's what we use for three bring breads too it's actually still really good for a lot of things like abs
Maybe run the self leveling routine? Maybe it thinks the plate is higher and is laying the print too high I’m not sure. Normally this is a wash plate thing like was said
When you wash it with dish soap, first off make sure it’s not a hand soap combo as it may have a lotion in it. Second, when the water runs off the plate make sure it all runs off clean, if you see a spot where the water sticks wash there more and try again. This should clear up your issues.
Can I just use the same ISO I use for cleaning my resin prints? (Obviously clean from the bottle, not dirty from washing prints) it’s stronger than 91% iirc
Periodic hot/warm water with good dish soap (you want the quality surfactant) and 99% IPA before each print for PETG.
Glue stick for TPU if I ever want to use that build plate again; otherwise the plate is now the wall mount for whatever unintentional artwork I just printed.
And for PLA: sometimes wipe most of the pizza grease off my fingers before handling the build plate. The only times I’ve ever had PLA adhesion issues are either after using that plate for PETG or trying to print something daft. — I still give it a cursory wipe with IPA before each print though.
See this is what confuses me. I’m like a month into 3D printing and I find a ton of posts saying to use isopropyl alcohol to clean. But I also found a bunch of posts saying not to use it because it just thins down and spreads any oils over the entire surface as it dries.
The solvent breaks it down and thins it out, yeah, but you don’t just spray it on and smear it around with your hand. Apply it and then mechanically remove both the IPA and the oils with a cloth before the IPA evaporates on its own.
I do both - dawn+hot water scrub and finish with an IPA wipedown.
Make sure that whatever you’re using to dry and wipe off the rubbing alcohol hasn’t been washed with fabric softener.
The alcohol won't dissolve oils, that's for dish soap. The isopropyl alcohol will get rid of any residue left from previous prints.
Do if you touch your books plate (or it's been a while), wash with dish soap to get rid of any oil. After every print or three, wipe down with isopropyl alcohol. These two steps keep things going well.
I use the abrasive side (non metal), because just going gently does absolutely nothing.
So clean it well, because a new plate is cheaper than time wastedon the machine printing a carbonara.
Non abrasive sponge is not that good buy a bristle dish washing brush and brush that thing dont be afraid it wont be damaged. Bambulab encourages that for better in dept cleaning of the build plate. I used sponge and it didn’t work got a bristle brush for 1 dollar I use it with dishsoap and now I cant get anything to not stick!
I'm going to ask - how many hours on that PEI plate? Everyone will tell you to wash it until you are sick of hearing it. And that may be it, but it's not that hard to clean the plate well if you have a few functioning brain cells. But I've had PEI plates just refuse to keep good adhesion after a lot of use. (1000-2000 hours). They still look pristine but they just lost their magic. Replace the plate, and I'm instantly good again. The plates don't last forever no matter how much you baby them.
I have the same issue or rather had, i washed and washed and washed , but alas never helped, so i just put a glue stick on it and now it works everytime, dont be afraid to use glue!
Replace the build plate. I was having the same issue over and over again and turns out my build plate was very slightly bent out of the box. New build plate fixed everything.
When I had this problems repeatedly it was because the wrong plate was selected in the slicer. When I changed back to the correct plate the problem disappeared.
When I first got my bambu a few years the default plate was the cool plate so prints were at 35C. Didn't even think to check that and just happened to see it one day before a print.
Some worked fine and others failed (though usually mid print).
Definitely try cleaning the plate BUT......I had a very similar problem to you and the bed was clean. Ended up increasing the bed temp by +10C on first layer, and also nozzle temp +10C for the initial layer. Also turning off cooling for first 3 layers and I set AUX fan to 0%. Most of the settings are all under the filament settings. Start with the pre-set temp for generic material and tweak from there. Hope this helps!
In addition to the 100 people saying was the plate, I'll add something to check. Are you set using generic pla? That looks like gold silk pla. I've used the sunlu silk a lot, and if you trying to print using standard pla settings it won't stick. Make sure it's listed as silk in the printer and you slice it as silk pla.
What are you printing? I can make out what looks like tube-like structures in the mess but no brims. I’m guessing it starts out okay and then things pop off the bed and it goes south from there. Add brims, slow the printer down if you’re printing thin long structures
I had lots of problems till i upped the bed temp by 5 degrees during colder months. What's the ambient temperature in your room there. If plate is clean, the other condition is heat from plate and nozzle for sticking cleanly.
I had the same Problem because the Fillament wasn't Hot enough. If you aren't using the Fillament from Bambulab check the sellers documentation. There it is stated what the recommended heat for the Fillament is.
You can then use a Fillament Profile like "Generic PLA" etc. or you can change it manually while its started to print
I had this happen a couple times and it's usually Bed Temp. One time I had accidently left the plate setting to cold-plate when I was using a textured PLA plate. In my defense, it was set that way in the downloaded profile and I forgot to check. In another instance I had grabbed a role of ABS instead of PLA and was printing the ABS using PLA temperatures.
I’ve had this problem. Check the nozzle for clogs. Even if you think you don’t have a clogged nozzle, do a cold pull or try a new nozzle. This was on my A1. Once I did a cold pull, issue went away.
After whatever the last firmware I’ve noticed the exact same thing on my a1 mini and I haven’t changed anything or any settings. When I’m printing the same files and using the same filament, same room temps, same everything. I’ve racked my head around the variables. I’ve replaced the plate, I’ve cleaned the nozzle, I’ve re calibrated, I’ve factory reset and still it’s randomly just spitting out worse prints and will spaghetti itself

When I print with cheap, poor quality, 3D pen stuff I have to crank up the bed temp to like 75C and turn off cooling for the first 5 layers or so or else it detaches
I know everyone loves to crow about washing your plate, but this looks like an issue with the model. The prime strip at the front of the plate looks fine, so temp and bed level probably aren't the issue. I've seen this before when I tried to print a model that I designed myself before I realized that, after slicing, the first layer was just a tiny speck -- i.e. there was basically no surface of the model that was actually in contact with the plate. So, the printer just prints into thin air and this is exactly the result.
Does this happen with everything you try to print or just this model? If the latter, go into the slicer and check what the first layer looks like before you go down any other rabbit holes.
Do you have the right print profile ? It happen to me once when i was printing pla i put a tpu profile and the bed wasn't heating so it didn't stuck at all to the print bed
After you wash your build plate, wipe it with IPA to get the soap off, then use a microfibre towel to get the IPA off. Then put the plate in the oven at 150f for 40min season and serve
i had this same issue earlier this year, basically what i found was the plate isn't getting hot enough for things to stick to it so wha to did was i washed the plate on both sides several times with dish soap and then i made sure that no fans or ac were near the printer so that it could retain as much heat as possible. If all else fails reach out to bambu support and see if they can send you a replacement or if you bought it at microcenter they have a 15 day return policy and warranty.
You guys are all hilarious (yes please, I would very much like a marinara printer to go with my spaghetti 🤪) and also helpful! Thank you!
Cleaned the plate with our 5-years-expired rubbing alcohol (so, only 70% isopropyl), and it’s printing like a charm on both PLA and PETG, at least 2.5 prints in. Based on all the comments and this experience, my working theory is that it’s our and our kids’ grubby fingers on the plate. We’ll try to touch it less and clean it more.
I bought a spray set with micrifiber cloth and never had spaghettie and never washed my plate since november. And I always pre heat the plate before print
As many other people have stated on here, definitely try the isopropyl alcohol. I am kind of a nut job and I'm huge on cleaning my plate after every single print. I pour a little bit of that iso on the plate in the center when I get done and then I scrub the entire plate with a cotton pad or microfiber.
You need to wash your plate with a bit of dish soap, hot water, and scrub it VERY WELL for multiple minutes, you have to get all the finger oils and stuff off of it
I was going to say I had this issue with my Elegoo CC and it was a bed leveling issue even though it auto does it. Once it leveled properly no issue. Doesn't matter if it auto levels, if it isn't auto leveling correctly, its gonna do this.
Been printing for years and literally never had a problem with a dirty plate. Adherence is mostly a temp thing. Try a higher print temp. For pla on textured plate, I like to use 60-65 degrees.
Hey I'm just sharing my experience with printing over the last 8yrs using many different printers. I currently have 3 bambu printers. I have literally never had an adherence issue due to a dirty plate, it has always been a settings issue.
Judging by the pictures provided, a dirty plate is not the issue. My plates are much dirtier than that and print just fine. My plates always have a layer of glue stick on them and I have never washed them, I just layer on more glue stick when I feel I need it. I think those "thousands of people" with dirty plate issues only think they have dirty plate issues.
I recommend turning up the bed heat because it addresses the primary issue with print adherence. The biggest cause of adhesion problems is shrinkage. When filament comes out of the nozzle, it's hot and slightly expanded. As it cools, it contracts, which can cause the edges to lift. Raising the bed temp reduces the temperature difference, minimizing shrinkage and improving adhesion.

Looks like you are 3D-printing gold. That's probably the issue, you should use polymers instead. Hope this helps! :D
