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.

First thing, just because it’s new from manufacturer doesn’t mean it’s dry. Don’t know lw off hand, but drying helps eliminate variables

Good idea. I would have expected new filament to be dry. If nobody else comes along and says: It’s definitely ‘this’, we’ll try to dry it. Thanks.
