Comment on Issues with model, slicing or printer settings and/or calibration?

  Gyroid infill used to be the default in PrusaSlicer, but they changed it to grid when the MK4 came out with input shaping and much higher speeds. Straight lines gain most from the increased acceleration. Gyroid will now make your printer vibrate like crazy.

  Good to know - don’t think my neighbors would be all to pleased with additional noise (and not me either).

  This is also not cubic infill, that’s another one (which I would recommend over grid for structural pieces). I actually almost always use Adaptive Cubic infill, which saves a lot of filament.

  Ah nice, it seems that the adaptive cubic will make larger pockets? Neither cubic nor adaptive cubic seems very… cubic to me, though. Why is it called this?

  So far I’ve not been making any structural pieces, but that is something I will remember for when I do.

  I also believe that your print would probably had turned out fine in the end, it doesn’t seem like there were any catastrophic failures in your photos, despite the noise.

  Hm, OK, maybe - I think however it would have been difficult for me to keep it going when it sounds like I am destroying the printer for every layer

    Adaptive cubic does indeed make larger pockets in areas that are far away from walls. As for the name, I myself imagine cuboid shapes standing on one corner. Prusa has a great page on different infill types: https://help.prusa3d.com/article/infill-patterns_177130.
    The only advantage I can think of for grid infill (that you're using) is that it reportedly makes better flat top surfaces.

    I manage a few Prusa printers at a school, and have set the default profiles to use 15% adaptive cubic infill.

    I change the infill in the following cases:

    • Large decorative item: Support cubic.
    • Piece that requires strength: Cubic , 20%, maybe add an extra perimeter
    • Very thin & tall parts: Rectilinear
    • Thin & flat: Grid

    I wasn't there to hear it, I might have felt the same :)

      Thanks! I’m saving that link, and I’ve also saved your list of when you change patterns for future reference.
