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.

    @i_like_water i’ve printed this plane twice using the same filament (3D Lab Print PolyLight 1.0), on my Prusa i3 Mk3S+; once using the pre-sliced gcodes from 3DLP, and once sliced from the 3FM files.

    If you’re using the gcode or 3MF files provided by 3DLP then the remaining variable is the filament itself.

    3D Lab Prints filaments absorb moisture more than many othe PLA formulations. They recommend (on their Discord) to always dry new spools, and store them in a drybox.

      Oh, first hand experience with this model, nice. In that case, I’ll put drying the filament and printing with open enclosure, which someone else suggested, to the top of the list. Thank you.
