I went through a calibration with this filament and everything looked good. But when I printed these, the tops don’t look that great. One of them looks melted through. What happened?
I used Sovol Tri Color Silk PLA, nozzle 0.4mm, 220C, layer height 0.20mm, Hilbert Curve pattern on top.
Looks like you may need to adjust your layer height down a bit. I would also consider increasing the number of exterior walls and maybe your infill as well. You could play with dynamic layer height in this region. The issue is that the gradient is too much between layers I believe.
For that snap tooth you are going to need to be it up. Looks like you are up against nozzle diameter dimension so, is not going to fill in unless you make it bigger.
@Level23 For exterior walls, do you mean wall loops or top shell layers? I increased the infill to 25% and adjusted down to 0.16 layer height
I would drop to .12 for layer height and increase the wall loops.
@Level23 Okay, so I did 0.12 layer height, 25% support cubic infill, and 5 wall loops. 215C first layer, 205C for the rest of the layers. Now I’m getting this:
Did the print fail or did you stop it?
Maybe also switch to Gyroid infill. Have you tried using the default profile for generic silk? 205 is awfully low for any kind of PLA…especially at the speeds that Bambu prints at. I think you’re not getting good layer adhesion on top of the gradual incline issue.
@Level23 I stopped it. I didn’t want to keep going with the fins looking like that.
I eventually figured it out though. 0.08 layer height, 7 wall loops, 9 top shell layers, 25% lightning infill, 10% infill/wall overlap, 100 mm/s outer wall, 250 mm/s inner wall, 200 mm/s top surface, first layer 215C, the rest 205C. There’s still a bit of roughness on the one fin, but it’s the best looking so far. Would raising the temp remove the roughness?
Looking much better! It should help to raise the temp a bit.
You might try a temp tower.
