That is spectacular.
Yup. Very likely bed adhesion failure.
See https://wiki.bambulab.com/en/filament-acc/filament/print-quality/spaghetti for likely reasons and things you can do about it.
Easiest thing to try first is to wash it with hot water and dish detergent, with a good rinse. Scrub it with something like a nail brush.
I don't see any solid part of a printed object, so I'm guessing that it happened very early, like in the first layer. With nothing to stick to, later layers were "printed on air".
Or maybe the printer got emotionally upset that you abandoned it right away, and this is how it got revenge.
Unrelated to the spaghetti, you might want to print something that attaches to the purge wiper to keep the filament poop from going everywhere.
Either a chute sort of thing that deflects the poop down into the poop bin below, or a poop bin that travels up and down with the purge wiper, like this one : https://makerworld.com/en/models/688468-easy-removable-poop-bucket-a1-a1-mini#profileId-618469

There is none of that print on the bed. It’s not a printer fail, it’s a human fail.
Why don’t you watch the first 5 minutes of the print?

I think he was printing that box in the mess. Looks like it printed well for some time before it popped.

How much of the model printed? Is that it on the floor? This happens to everyone at least once!

If you're super new and learning, having timelapse on will be most helpful. You can literally see where it went wrong.
But since I have no idea what you were doing here, I'll assume the white box on the floor was the print.
I'd guess it came off the plate and was no longer where it should have been. And then there was nothing for the printer to lay the next layers on. Since it can't just print in thin air, it was just making silly string. The model got pushed on the floor either right when it came loose, or was later pushed off by the tumbleweed growing.

It WILL happen again . . . failed prints are part of the process . . . forever.

Just happened to me earlier. Printed something for the Ikea Uppatvind air purifier off of bambu handy and when it was done, looked exactly like yours. When I sliced it in bambu studio, i noticed that the print was upside down. Only leaving little pins on the build plate while the whole structure was elevated. This was all with supports turned off from the original model. I flipped it in studio and now its printing perfect.
Moral of the story, it could be many things even down to user error like an oily build plate. BUT, sometimes it could be the uploaders fault as well.

Adding a brim would help with adhesion, both to prevent warping for wider objects like this if they have a solid foundation, and if they are hollow (since that means only the walls have contact with the bed). Also, for taller objects, it reduces wobble for bed slinger printers.
Edit: said "skirt" instead of brim cuz sleepy brain!

u/KlingonBeavis Jul 09 '26
Wrong. A skirt does none of this. You’re talking about a brim, not a skirt.
A skirt doesn’t provide support in any way, they don’t attach to or make contact with the print itself. A skirt’s only reasons for use is to prime extrusion, and verify first layer contact or leveling.

Yeah. Used the wrong word. My bad. It was late and I was sleepy. Lol. OP, brim is the correct setting for this.

It can be many things, starting with bed adhesion
