Posted · I'm really puzzled

I printed a solid 100mm by 5mm disc.  Didn't want any infill, so I set the wall layers to prevent infill.

It printed the outer section first, which makes sense I guess, then the inside.

But the end result was not what I expected.  See picture.

It's very "shaggy"

What's happening here?

 

Extrusion was just calibrated to this roll and print temperature, and speed.

    If anything it's over extruded.   I just re-checked the extrusion cal with this roll and same print temp, and it was dead on.

    I'm running it again now.  Looks ok so far.

    "Looks ok so far." - Said the guy that jumped off the skyscraper as he passed the 10th floor.

     

    This is the back side of the print from your image.  Something is going on because nothing is welded together.  It's just a bunch of lines.  It's really easy to see the layer below the top layer.

    I'm not sure what you mean by "Back side", this is the top (last layers printed)

     

    The fuzzy looking parts around the perimeter are excess filament pushed over the cliff.

    There's also the spiral pattern which I didn't expect.

    The disk is slightly over thick at 5.12 mm.

     

    This is not anything I've hit before.

     

    Snapmaker A350, ABS, 245/95  Filament is in a 55C drybox and then passed through a 90C inline dryer, and the whole path is enclosed in PTFE tube.

    Not back side, the top edge of your photo.

    Without a file or something to look at (other than a photo) it would just be guessing.
