ASA Delamination

Basic Information:

Describe your issue:

I am printing a large piece with ASA. I have issues with delamination. I am printing with a .06 tip, extruder 260c, bed temp at 110c,
Inside the case is around 40c.
Layer height 2 parameters 4.
I have previously tried with a 40% infill with
2 parameters and get less delamination.
It seams i get each parameter delaminated with or with out infill. I have also raised the extruder temp to 265c but did not help.
My apologies if I have posted incorrectly.

Not quite a Klipper issue, isn’t it?

0.06 mm? That is very tiny.

Do you have an enclosure?

I would guess you mean 0.6 mm nozzle.
If so:

  • Printing temperature too low
  • Chamber temperature too low
  • Measure your bed temperature. It should not exceed ~90°C on the surface (although this is minor but the first two points are key.)

In addition I’d recommend to not go much above 80 mm/s speed.

I’m a big ASA fan and according to my experience there are really crappy ASAs on the market. Actually the worst I tried was from a renown brand, the Formfutura ApolloX ASA.
My current favorite is the ASA from Polymaker.

Edit:
And I forgot the most important point: Ensure that the filament is extremely dry, even more so than the driest spot in the Mojave Desert.

Edit 2:
BTW, looking at your pictures it seems severely under-extruded (although hard to judge from the pics). Typically I run at an extrusion factor of 0.94 for ASA but this requires that things like temperature and velocity match together.

Yes .6mm nozzle.
I am using ASA from polymaker. I do have a drybox that I run right to the printer, however I don’t have PTFE from drybox to the enclosure. I will order some PTFE.
My extruder temp should be with in 240 - 260.
My bed temp is to be with in 75 - 95. I will adjust that as well.
My speed is 30 mm/s first layer then up to 50 mm/s after.
I will adjust the extrusion factor. currently 1.01
Also adjust my under extruding.

Thank you for your time.

Yeah, I’m not sure it’s technically delamination if the perimeters were never laminated to being with. It looks like you are severely underextruding or the perimeter spacing in your slicer is set too high. Possibly both. The top solid infill looks underextruded so I’d definitely start there.

That print is way underextruded, the entire top is a grid and not a surface, too.
I’d check the rotation distance first, this is way beyond a bad flow setting in the slicer.
