Top layer not printing correctly?

I wanted to print something that has a hexagon surface pattern on top.
I created this hexagon pattern, it is 0.2mm high, and starts at 2mm. I am printing with 0.2mm layer height, so in theory, the 11th layer should be printing this hexagon pattern.

It shows up fine in the “Prepare” tab in Bambu Studio. However, slicing doesn’t show it, nor does it print. I don’t understand why.

What could be wrong?

Can you provide pictures of what you are trying to do?


This is the object. The bottom is 2mm high, and the 0.2mm hexagon pattern starts at 2mm.


Here it is in Bambu Studio. Shows some shading, but the pattern is there.

But when I slice it, the pattern is not there, with 0.2mm layer height. Not even with 0.08mm layer height.

ok but is the line width within the hexagon pattern bigger than the nozzle diameter you are using?
did you try slicing with Arachne wall generator selected?

How wide are the raised hexagon sections? They need to be at least .4mm or the slicer will ignore them.

There is a better way to do this by adding a cube with the top and bottom layers set to 0 and using honeycomb infill.

I just used the base 0.20mm profile and mine slices the 0.20 mm hexagon layer at 1mm wide. Note, I am using an older Orca profile right now (1.90), but I believe that shouldn’t matter very much, if at all.

Correct me please I got it wrong but you want this hex pattern embedded into the top surface?
Or it is raised above the surface?

In case you means the first:
Create the model in TWO parts.
Have the base model with a fully flat surface.
Cut out your hex pattern.
Fill the cut out with the hex pattern.
Just to be clear:
You create the base model, remove the pattern and place another model into the void.
Export both as STL files and import into Studio as a multi-part model.
Now you can go into the object tab and set what you need for the base model and for the hex ‘infill’ individually.
Try to set the print order so that the pattern is printed after the base, gives cleaner lines.

Thanks! Arachne seems to show the pattern!

They were (are) 0.2. I will try the cube you are suggesting, thank you!

Thanks, I will give that a shot too. The hex pattern is raised above the surface.

If it is raised it seems to be a slicing bug.
Using two models should fix this as well the same way it can for being flush with the surface.
