What I learned from my first few months with a Bambu Lab A1 3D printer, part 1

Summary

For a couple of years now, I've been trying to find an excuse to buy a decent 3D printer. Friends and fellow Ars staffers who had them would gush about them at every opportunity, talking about how useful they can be and how much can be printed once you get used to the idea of being able to create real, tangible objects with a little time and a few bucks' worth of plastic filament. But I could never quite imagine myself using one consistently enough to buy one. Then, this past Christmas, my wife forced the issue by getting me a Bambu Lab A1 as a present. Since then, I've been tinkering with the thing nearly daily, learning more about what I've gotten myself into and continuing to find fun and useful things to print. I've gathered a bunch of thoughts about my learning process here, not because I think I'm breaking new ground but to serve as a blueprint for anyone who has been on the fence about Getting Into 3D Printing. "Hyperfixating on new hobbies" is one of my go-to coping mechanisms during times of stress and anxiety, and 3D printing has turned out to be the perfect combination of fun, practical, and time-consuming. Getting to know my printer My wife settled on the Bambu A1 because it's a larger version of the A1 Mini, Wirecutter's main 3D printer pick at the time (she also noted it was "hella on sale.") Other reviews she read noted that it's beginner-friendly, easy to use, and fun to tinker with, and it has a pretty active community for answering questions, all assessments I agree with so far. Note that this research was done some months before Bambu earned bad headlines because of firmware updates that some users believe will lead to a more locked-down ecosystem. This is a controversy I understand—3D printers are still primarily the realm of DIYers and tinkerers, people who are especially sensitive to the closing of open ecosystems. But as a beginner, I'm already leaning mostly on the first-party tools and built-in functionality to get everything going, so I'm n...
