Try reducing the print speed and cleaning the bed with acetone before each print.

You could print something on top of it, like a giant square covering the whole affected area. You should use some slightly higher temperatures than usual to make it adhere good (e.g. 75 °C bed 210 °C hotend), make sure that you print several layers. There are 2 options removing the new print when there is an elevated temperature in the bed left after ...

It sounds like it may be due to uneven heating. Check with an IR thermometer to make sure. If you're sure the bed is clean and has even heating, you may want to try a different surface. G10 is cheap and almost always perfectly flat.

Problem was displaced by a factory reset of the 3D printer FlashForge Adventurer 3. Right: white PLA only, left: transparent PLA bottom layers plus white PLA above. View of the bottom sides. No difference of print bed adhesion now. The reason of the problem was not found, but print bed adhesion is good after the factory reset for both white and transparent ...

Same G-code slice? The main cause of warping is temperature. If this is kept as a control variable and you have these results, it may be because of a different temperature the filament requires. Check the filament specs and adjust the bed/nozzle temperature to make the temperature difference smaller. Edit: Another reason it might be needing different ...

Plastics that shrink a lot (like ABS) do better with a base plate shape that has no corners. One approach is to put a one layer circle on every corner (ears). PLA has a very small shrink factor, so there isn't really much of a difference for different shapes for the first layers as long as there is enough area in the base for the height of the part. If you ...

On a heated bed the ideal setting is where the plastic becomes sticky, but not hot enough it changes shape. For PLA that's usually around 60 °C. You want enough plastic on the build plate to stick to it, but not so much it won't come off. Use support to increase cIf the majority of the bed is covered it might stick too much. My rule of thumb is to look at ...
