This is PETG, one was left out in about 40% humidity the other was dried to about 20%

    I’ve had PLA spools go bad due to age, so I can definitely attest to them eventually crumbling out of existence, good to do the bend test if you’re not sure, if it snaps/breaks when you try and fold it in half, it’s too old and the print will come out much more brittle than you’d want it to be.

    True for the location dependency, but even here with about 20-30% humidity, it’s pretty noticeable after a week, granted, that’s assuming you leave it out and open, storing in a dry box or in a vacuum sealed bag with a desiccant between prints will help prolong that period immensely in my experience.

    Marketing definitely has had quite a creeping presence into 3D printing in recent years, and similarly to gaming, it seems to be targeting the enthusiast class, so trying to convince people to try printing with more fancy (and toxic, and hydrophobic) materials than just the standard run of the mill PLA and PETG and upsell them on all the accessories before they’re actually needed.

    Makes you wonder how much of all of this is gonna end up in the dumpster or in the attic at some point

      I know. As an old toolmaker that managed a few shop floors, inventory management is something I practice with a vengeance.
