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.

    Could be too much heat so when film retracts some still drip and causes that. What temperature are you printing at?

      First layer 240 deg Celsius, other layers 245 degrees.

          It’s LW-PLA, that foams, could be necessary for the foaming. We just used the filament by the manufacturer with their model files and presets.

              Not yet, another commenter also suggested this. I assumed new filament to be dry. We’ll try that, if nobody else has a definitive answer.
