I wouldn’t say they are perfect, but they are not mediocre - I can’t speak for the A1 but that’s not my impression of the X1C which I’ve had for about a week.
I started 3D printing with a reprap i3 something like 10 years ago. That printer has long gone, but in addition to my new X1C I also have a very heavily modified Creality CR10 which I’ve been tuning/enhancing for years and a standard out of the box Ender 3 Pro. Now my CR10 has an E3D hotend, Titan extruder, BLTouch bed levelling, can print up to 350’c, has multiple beds for different materials, remote access/printing with OctoPi and all sorts of other enhancements. It prints very well, but printers like that need maintenance, the various software components need updating and then when something goes wrong it takes a lot of time to troubleshoot and resolve. Tasks like tuning the pressure advance and extrusion multipliers with new filaments to maintain dimensional accuracy (parts that fit properly) take a fair bit of time. Tweaking and tuning print profiles to get good results takes a lot of time. The Ender 3 is a simple printer in its stock form, it’s pretty good at basic stuff and I only really use it for small PLA prints. The main reason I have it is that the CR10 would often break or have an issue which put it out of action and I’d need to be able to print new parts to get it running properly again.
3D printers became a hobby in itself and took a lot of time, rather than the original intention of the 3D printer being a tool to produce parts for other purposes. The beauty of the Bambu printers is that even a person with no previous experience can purchase one and out of the box start getting results that have taken me 10 years to obtain via the hobby printer route.
My only real gripes are the filament membership thing which is a waste of time/money if they can’t keep filaments available and in stock (or at least let you backorder them), and that the RFID tags are closed source meaning third party filament suppliers can’t include Bambu compatible RFID tags, and you can’t create/update your own tags for filaments.
So for me it’s about time. Life is busy, time is at a premium and the Bambu printer gives me the ability to reliably print items on a commercially supported machine with easy access to spare parts etc - without all of the faff. The 3D printer can become a tool rather than a hobby in itself. This is something that previously cost a lot more than Bambu’s offerings and was only really viable for businesses.
I’m happy with my X1C+AMS and will be dismantling my Creality printers for parts (to make a small CNC machine).
