  • Prusa printers are also “turn on and print” nowadays, except if you buy it as a build-it-yourself kit. And even that is like a more advanced Lego kit, the instructions are very thorough, with community comments for every step. They’re very easy to repair, and you can usually buy upgrade kits to upgrade them to the next version.

    I agree that If you don’t have a filter system or some way to vent the printers outside, stick to PLA for indoor items, PETG for things that might be in the sun, and potentially TPU for rubbery parts. You don’t even need an enclosure for those.

    If you have the budget for it, get a Prusa MK4S or Core One. In my opinion, the only reason not to buy a Prusa is the price.

    In firefox there’s an extension that suspends tabs that haven’t been active for a while. I guess that chrome has something similar.

    Firefox does that natively now, AFAIK. Also, a popular Chrome extension that did the same changed hands and turned to malware a while back, just FYI.








  • 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?

    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

    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

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