I don't even care much about cost, but the Bambu Lab printers are simply better. I have been selling my Prusas (MK3S+ and XL), because they are just too much of a hassle. Prusa has fallen behind in R&D, the Bambu Lab printers work better, are more automated, have more nicely engineered features (having to babysit my XL and wipe the dripping filament off the print heads was such a disappointment).
And yes, I have had to fix both brands. The repairability of the Prusa is largely a myth, you still need to order replacement parts from Prusa, just as with other brands.
It cannot be overstated how critical good defaults and “just works” are for any kind of mass-market product.
Knobs and toggles to allow enthusiasts to dial in everything perfectly aren’t a bad thing. You don’t need make your product a featureless orb. That said, users shouldn’t need to tinker around with any of them to get up and running or for basic use.
This is where Bambu excels. More involved printers are simply not interesting for many people outside of the 3D printing sphere, even if they’d become enthusiasts after buying a printer. They need a “gateway drug” of a printer that’s dead simple to use and get good results out of to even consider buying one. After that they might go down the rabbithole and seek out more technical options, but jumping straight to tinkerville is just too far of a leap for most.
I got into 3D printing a year ago and decided on the Bambu. I started with a P1P to see if I'd like it, got an AMS, got an enclosure in the span of about 9 months. Would I have saved money if I got all of that at once? Of course. But I didn't know if I'd like 3D printing. The P1P worked so well and so easily, it was a "gateway" and did suck me in.
Case in point, the AMS. The Bambu system is so clean. It sits on top of the printer even if you don't have an enclosure. The Prusa system requires you to lay the spools out on runners on the table, taking up a ton of desk space.
Prusa is good enough for me. I owned both Bambu and Prusa latest generation printers. Both products got their shares of downtime so from my perspective either are pretty interchangable.
And yes, I have had to fix both brands. The repairability of the Prusa is largely a myth, you still need to order replacement parts from Prusa, just as with other brands.
I wish Prusa would catch up with their R&D.
