  • Infill has massively diminishing returns. I don’t think 100% is required. Usually it’s much better to increase the number outer layers.
    That said, depending on the cost scaling, the possibly positive effects of extra mass, and how much I want to avoid a second attempt, massive objects can make some sense.

    PLA becomes brittle with moisture (from your hands and/or air). I would recomment PETG / ASA / ABS (ascending order).

    Yes, basically all CAD and slicers (3d-printer software) can mirror. PrusaSlicer for example can mirror and then save to stl again.



  • The only thing I think the Mk4 is missing is a camera / octoprint support, but I can live without those.

    Firmware 5.1 enabled octoprint support.
    Not as far as they’d like, but it works. From memory what is missing is some support when Local and Octoprint mix (i.e. when you print locally, octoprint can’t stop the print. Bit annoying but far from a dealbreaker imho)


  • TheYang@lemmy.worldto3DPrinting@lemmy.worldPrusa or Bambu?

    I bought Prusa.
    I hope to be able to still use the machine in 10 years.
    I’m much less confident that BambuLabs machines will be able to do that, than Prusas. This is because of multiple reasons:

    • There are design decisions of Bambu that I do not trust (bushings on the x-axis on p1 and x1 machines), which track with the decisions of DJI which I didn’t like and where many of Bambus people came from.
    • I much prefer to support a comparatively independent european maker than a chinese-bank backed one.
    • I do trust Prusa much more to offer long-term support than Bambu
    • I prefer to support Open Source, and I do think Bambu is still violating licenses (which imho should not be supported/accepted)
    • I do not like Bambus AMS design. Their reliability costs quite a lot of filament.

    But Bambu has Prusa beat on price for similar performance. By a significant margin.

    And to further your question, I’m not sure Bambus Printers have that much more “simplicity” in use than Prusas. Especially if you buy pre-built. Both are rather plug and play.

    In short: I fear / believe that Bambu is exactly the kind of company that ruins products. Underbid your competition, cut costs at the customers expense. Why provide updates to your old products when you make a new gen? Why use a part that lasts longer than the required period for repairs? etc.
    The fact that they started regular sales this year (I Believe before was pre-order?! would have to check) and already have 3 different platforms out (X, P and A) is quite a lot of fragmentation. Maybe they designed for that from the start, but… we’ll see. AMS and AMS lite also seem quite different.
    They may even be the worst kind, that underbids the competition and takes development costs as losses to destroy the competition until you are an effective monopoly, at which point you can fuck everything up way more (increase prices, cut quality / development etc)
    In Fairness, they may also not be. They may also have excellent long-term reliability and support. Maybe in 5 years P1 and X1 still get feature updates. Maybe the design decisions turn out to be outstanding.




  • Well, from the EUs perspective, while the US is certainly generally an Ally, it is sometimes a rather tense relationship.

    I’d argue, you could describe China pretty similarly, although that would be somewhat disingenuous, as I think EU and US values are more similar than EU and Chinese values.

    Anyway, if you don’t want the data of your people to go to some questionable other country, you’d have to forbid US social networks as well.
