Hi, I’ve tried to print a model plane for my father. It’s this model, using this LW-PLA right after purchase.

As you can see in the image of this post, the print is going well until it reaches a certain layer, where the filament does not get deposited properly for the entire layer, only intermittently. The following layers then, of course, have the same problem and I get this failed print with these “frayed ends”. Additional attempts failed the same way at a similar layer count.

If someone has some experience with lightweight PLA (LW-PLA) and knows what can be done to solve this, I and my father would greatly appreciate the help.

Thanks in advance.

Edit: Additional info: I’m using the PrusaSlicer files from the linked page. Edit2: The printer is Prusa Mk4.

    If it’s always happening at the same layer I’m skeptical thatl it’s a drying issue. You try printing with a normal pla to see if it’s filament related even? If it is, agree with doing a temp tower. I’ve been doing that with most new filaments. Try slowing print speed too

      I agree. Can you put the stl in the slicer and run thru the layers. See what happens around this height? I’ve had trouble with my prusa mk3 always shifting at the same height and it was a firmware issue. Happened out of the blue and a refresh fixed it.

        The layer doesn’t look unusual compared to the previous layers, but thanks for the suggestion.

      Do you mean the exact same model but another filament like regular PLA? Other models with regular PLA is no problem.

        This model. Whenever I have trouble with a print first thing I do is get the best most familiar reliable prusament pla I have and try same print with that.
