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.

Have you adjusted the speed settings according to what the manufacturer says? LW-PLA can only be printed at a very low speed or else it clogs. It also needs constant speed. For example for colorfabb LW-PLA, I had to set all speeds to 40mm/s.

I'm using manufacturer (model designer and filament manufacturer) provided files. If I remember correctly, I tried a lower speed, but I will experiment more with the speed since it was suggested so often. I think, it should be a constant speed, since it's all external perimeter and looks to be set to a constant value.
