I purchased an A1 a few weeks back, and I’m having issues with the build plate when printing tree supports using white and grey Inland PLA from Microcenter
Specifically, the tree supports are leaving a thin residue that i can only remove with a steel woll scrubber, which in turn (annoyingly) is STILL leaving (less) residue but also small ‘bald’ spots where the texture has been scrubbed off.
In addition, in one of my first prints, i printed a base to a spaceship mini game, and a large chunk of coating came off on the opposite side of the plate.
Does anyone know how to get that residue off another way that doesn’t damage the plate? Do i just need to get a new plate?
I was told how easy this was, and, have to say, it’s anything but.
On my textured PEI sheet, I use hot water and soap for cleaning. Once dry, I thoroughly wipe it down with IPA until all traces of the previous print are gone (especially if any ghosting occurred).
If the PEI layer has been removed, that section of the build plate is compromised and will no longer function as intended.
I’ve only used filaments from Bambu Lab, but if you experience ghosting, applying a thin layer of glue stick might help facilitate easier print removal.
Build plates are also considered consumable parts and will degrade over time.
But if you’ve only had it a few weeks, it sounds like the coating on the plate could have been defective.
I’ve been using my A1 for months, and no problems at all with the textured or smooth PEI plates. I don’t use a scrubber on them either - just the plastic scrubber of a scrubbing sponge with dish soap. I wouldn’t recommend steel wool scrubbers!
Are you waiting for the build plate to cool down to room temperature before trying to remove the prints - they’re much easier to remove once cooled.
Hot soapy water and a scrub brush with plastic bristles didn’t do the trick. Also read that the plate could be sanded (which did nothing but create a dull spot) and steel wilool could be used in the bambu wiki.
I think you have a bad build plate or a filament issue. What you are describing shouldn’t be happening. Suggest you go back to your seller. I have printed over 100 hours and many objects without any problems and have not done anything to my pei plate, not even had to clean it. I have used Bambu PLA-CF and Creality PLA filament so far. BTW it should be easy. Yes, get a new build plate. and try different filament. Good luck.
Also vorweg ich drucke haupsächlich PLA zwischendurch auch PETG.
Ich reinige Meine Bauplatte nur alle paar Monate oder nach Wechsel des Filamenttyps mit Spüli und warmen Wasser. Ansonsten wische ich sie bei Haftungsproblemen mit einen Küchentuch und Brennspiritus ab. Weil die meisten Haftungsprobleme durch das Fett der Finger kommen.
ich sollte mir echtmal Handschuhe besorgen zum entfernen der Drucke von der Bauplatte.
Beim reinigen der Bauplatte mit Spüli und warmen Wasser nutze ich die Scheuerseite eines Spülschwammes. Ich bewege den Schwamm ohne Druck mit kreisenden Bewegungen über die Bauplatte.
Was auch zu empfehlen ist auf einer Seite nur einen Filamentyp zu drucken. Dadurch veremeidet man auch Haftungsprobleme durch Rückstände. Wenn man zum Beispiel Pla drucken will und vorher aber PETG gedruckt hat.

First of all, I mainly print PLA and occasionally PETG.
I only clean my build plate with washing-up liquid and warm water every few months or after changing the filament type. Otherwise, I wipe it down with a kitchen towel and methylated spirits if there are adhesion problems. Because most adhesion problems are caused by finger grease.
I should really get some gloves to remove the prints from the building board.
When cleaning the building board with dishwashing liquid and warm water, I use the scrubbing side of a dishwashing sponge. I move the sponge over the building board in a circular motion without applying pressure.
It is also advisable to print only one type of filament on one side. This also avoids adhesion problems caused by residues. For example, if you want to print Pla and have previously printed PETG.
My A1 PEI textured build plates are always washed in warm to hot soapy water and dried using a paper towel and IPA before each use - I have not had any issues
People advising about washing the plate forget about one thing - the quality of PLA also matters.
At some point I got myself a bit of PLA-F from Bing3D - it was horrendous, I had to make special profile for it just for it to not destroy my plate let alone print correctly and there’s still a bit of residue from it on the plate despite multiple washings and printing decent stuff.
Here’s my tip: throw out the Inland PLA from Microcenter, get yourself some decent PLA from a reputable brand and with all that steel wooling you did on your plate - get yourself a new plate.
2nd tip: when getting a new filament of unknown quality, print a small sample (After drying it) - if there’s a problem and you’ve got loads of it, tune the profile for that specific brand.
Re: “and there’s still a bit of residue from it on the plate despite multiple washings and printing decent stuff.”
Try printing some PLA over top of that spot, 10 degrees hotter than normal (both nozzle and bed), and with bottom surface flow ratio 1.10. It’ll look crappy and overextruded, but it smashes plastic in all the nooks and crannies. It should pull up when you remove the thing you printed above it. A simple 100x100x0.2mm cube that is only 1 layer tall will suffice. (or however big the area of debris is)
Ive read the wiki , i took it with a pinch of salt and considered the job from my own point of view , pei plate + water based glue , which if applied correctly will also add an additional easier to clean layer
don’t use that IPA on your plate.
