“When I went looking at printers again Prusa was what I assumed I'd get but after looking at Bambulab, their A1 is about 1/4th of the price while being better than the Prusa MK4.”

I had a Makerbot 2X in 2014 and it required constant janitoring every time I wanted to print. I built a Prusa MK4 this spring; it calibrated itself and printed a great looking piece right from the get-go. The difference is night and day.

So let's discuss Prusa: The Bambu A1 competes with Prusa's MK4 model but is signficantly cheaper, faster and does more. For the price of one Prusa MK4 with shipping I could buy three Bambu A1 printers or two Bambu A2 printers plus the AMS addon which adds multi-color printing. I would argue that was always inevitable, Prusas are laughably overpriced and it's not like they're open source in the sense that you can build your own.

There is a lot more community value in providing hackable low cost hardware like Creality did with the Ender, becase then people that have time but not money can you know... [...] And then develop open source software or make models for it with that time.
I just bought the prusa mk4 kit+enclosure, spent 20+ hours building it, and now I can’t stop printing upgrades for it(mostly the enclosure). I sealed the enclosure a bit, did the squash ball feet mod for the printer(it’s silent now), and I’m currently printing this:
Did you know that Prusa Mk4 printers have a touchscreen? I DIDN'T. I've been using this printer for years, and only JUST found out that it has a (disabled in the settings) touch UI.
Almost a year later, with our son back from college for the holiday, we have completed building the Prusa MK4 3D printer that he got as a kit last year. Crazy how much better the printer tech has gotten over the last few years!
While this is true and I own a Prusa MK4, they're so behind it's not even funny.
After yet another layer shift, I've decided to scrap the SRMTHFG Super Robot print for the time being, as I have other projects that need priority at the moment. Really disappointing, especially since it's been a long time since I've had this sort of problem with my Prusa MK4.
The A1 is pretty close to magic, but I think it’s fairly close to the capability of the Prusa Mk4 (which is more expensive of course). I use mine in LAN-only local mode and use Orca slicer so it’s not connected to Bambulans cloud.
I got a Prusa MK4 and it does a fantastic job. The only thing that sucks is that it can only do 1 color at a time without switching the filament mid print.
