Reverse Elephantfoot

[cyan cairn]

So i know what to do if you have a elephantfoot on the surface that is facing the print bed but i never had something like this on the top layers. Any suggestions?
Printer:
Bambulab P1P
PLA 220° nozzle

AI Help

If you are experiencing elephant foot on the top layers of your print with your Bambulab P1P using PLA at 220°C, you may want to adjust your first layer settings. Try decreasing your initial layer thickness slightly to mitigate the elephant foot effect. Additionally, ensure your bed leveling is accurate to avoid the nozzle being too close to the bed. Experiment with adjusting your extrusion multiplier to fine-tune the top layer appearance.

Did u iron it? You might also just have too high flow rate so when it prints it’s pushing out of the side

u can also try searching for "pillowing" and see if there any suggestions there / if it matches...

Its a Bambulab filament and i didnt adjust the flow rate. But with the orginal filament it should be ok right?

And it looks like its not just the top layer but the last 3-4 layers

[reef mulch]

It’ll be all your top layers

Their settings are pretty good but not perfect, filament can vary from color to color, batch from batch

If you calibrate it yourself you can get even better results

If it’s a large area even a small amount over can cause it, the small overflow adds up

Did the part also maybe come off the build plate?

That would cause this too

Like if the corners warp up

I just noticed this happening to me

Im getting same thing ( right sode was top surface)

[cyan cairn]

Really i tought if im irioning it only affect the last top layer

Can you recommend the calibrating of the filament within the bambu slicer?

[cyan cairn]

No it sticked Perfect.

Im printing the a part now without ironing lets see how this looks. Bc im not sure if i turned it on or off in the first pic.

[faint dagger]

usaully affect top 3 layers i think...
you could try reducing ironing flow in the slicer settings.

[cyan cairn]

It looks like this without ironing

[reef mulch]

I use orca slicer for my calibrating

[cyan cairn]

This is extreme now 💀

[reef mulch]

Looks weird

But it def has to do with the top layers

So I assume too high flow rate

If there isn’t enough space it has to squeeze out somewhere so it becomes wide

Might also have to do with layer time where the previous layers take less time so don’t contract as much, where the top layers have much more time to cool down/contract

[stone kraken]

Yup got same issue , ive done flow dynamic calibration, and all thr usual stuff already

Real pain for parts who need to fit together

[cyan cairn]

But it looks like the mid section is falling in too

[reef mulch]

That means this is prob the issue and it’s just shit filament

[stone kraken]

I have the issue and its polymaker pro , been using for years

[reef mulch]

Can’t speak to it, haven’t used it

But some filaments are more/less prone to warping

[cyan cairn]

I only use 2 walls and 8% infill. The part is not high but wide maybe i should use 3 walls an more infill to support the walls and stop the from falling in?

[faint dagger]

If you do a taller piece (even if it's skinny) does it still show up in the same place?
Could it be mechanical?

I will print a simple cube and see if it still occurs
