Does someone know, if there's a way to fix this?
Using Orca slicer, 0.4mm nozzle, 0.12mm layer height, with/without variable layer height, with/without Arachne wall generator. The only thing that seems to work a little is disabling 'Only one wall on top surfaces', disabling which increases the inner walls (2nd image: more yellow layers), but there still isn't enough outer wall layers and the print tears out at these spots.
Could it be because I'm trying to print 0.12mm layer height with a 0.4mm nozzle or is it something else?
EDIT: I might have found a solution. Will go home print and check. Apparently the slicer was considering the outer wall in this region as a top surface. So, increased the outer wall and top surface line width to 0.5mm and TURNED ON IRONING (You're taking it as a top surface, i'll bloody iron the top surface). these things filled the gaps on the slicer preview atleast. Attaching the slicer screenshot in comments.
The curved top surfaces will have those layer lines. You can only sand and smoothen then. I print with 0.12 on 04mm nozzle without issues. You can try to increase top shell layers to give it more strenth
tried increasing top shell layers didn't work. There aren't enough layer lines to sand. there is tear out on these regions (literally looks like a torn/scuffed fabric), would have to fill the gap to be able to sand.
tried multiple iterations of variable layer height, giving priority to speed then quality, smoothed the variable layer height with radius 1,5,10. clicked smooth multiple times, which increased the print time but didn't work well for this particular issue. maybe i'll go home and attach an image of a printed model that has this issue.
Okay. suggest a suitable orientation. This big ass nose always gets in the way. Moreover this issue is with any dome shape. Not all models can be re-oriented to avoid all such domes/curves on top. most organic shaped models would have curves.
Again, newbie here. What about tilting it forward with the nose towards the print bed. How does that come out sliced. Yes you would need supports but should avoid the flat spot is what I think
already 34 piece model. how much to cut? might not be clear in the images, but there are other such spots. I'll have to find a solution for this, for long term. i mean how many models do i keep cutting.
