    Part of it happened on those old days before COVD… When believe it or not, people already existed and did things.

    Part of it happened on those days since the COVID emergency ended. Believe it or not, it wasn’t earlier this year.

    Almost all of it happened before the US has gone crazy in Trump part 2. Believe it or not, it wasn’t 30 years ago.

















  • The humidity here varies between 3% and 100%.

    Things change from PLA being regenerated by being left open to it not lasting for two weeks before it needs drying.

    Unless you live somewhere where it’s always close to that low in my interval, I do strongly recommend a drybox to anybody wondering if they need one. At 60% humidity, PLA already visibly degrades way faster than you will use in a hobby.

    Also, in my experience, filament driers only help with close to dry filaments. The temperature you would need to really dry them is larger than the glass point of most plastics. Microwaves work better (I guess because they heat the water in an uneven way) but it’s still hard to regenerate very moist filaments.

    You need a bit less than 1/3 of it…

    But it’s supposed to be build in an ocean. Forests do not make for good logistics.

    (It’s also supposed to use a series of hypersonic iron pellets running inside a tube, that will explode and endanger a hundreds of km radius if something like even an air leak appears there… So yeah, the size is the least of the issues here.)
