The top lay after ironing looks like it’s has a skin disease with pits and missing areas. I am wondering is this the best I can get? The areas inside show uncovered first layer where as the area in green is nice and smooth. I am new to 3d printing (been about two weeks now). ‘so I don’t what to expect. I have tried changing a few settings, like line width but did now really help. Any suggestions. I am thinking of trying out the ORCA slicer, I understand it may have more setting? Anyways let me it this can be improved?

Requirement: Calibrate the filament / filament flow. Dry the filament. Filament with too much moisture can lead to various problems.
Increase the fill density if it is set low. Or, increase the top layers.
If the item warps, you will have trouble ironing, the filament removed at higher points at surface and depositing it lower points at surface where it has no business being.
If I were to guess. There’s a couple of possible causes:
- Under Extrusion - Possibly because the filament max volumetric flow is too low. If you’re using the Generic PLA profile, try switching to a Bambu PLA profile.
- Only using a single layer for your top layer. Try increasing the number of top layers.
- Printer is going too fast for the filament. Try placing the printer in silent mode which will slow it down by 50% and also double the amount of print time.
- Hotend is too cold. Increase your filament temp in 5-10 degree increments.
Orca slicer will not change a poorly tuned filament profile or if your filament is just not up to the task.
Try out a single layer print. You can do it in a couple of ways.
Download one from here.
Single layer print from Printables

Or you can set up your own.
Set up a Cube primitive and make it 250mm x 250mm x 0.1mm If there is anything wrong with your filament profile or filament itself, that one step will highlight it in a few minutes.
Alternatively if you want to save time, make the primitive 200 x 200 x 0.1
These are only troubleshooting tests. You’ll have to experiment of course to find your particular cause.
So far for my testing, I seem to have fixed the issue. I made the following changes to the ironing settings
Ironing speed changed from 30 to 20
Ironing flow changed from 10% to 15%
So far in my testing this worked….
