So...the thing is, the real competitors to the Prusa i3 printers
are open-source. Like, actually. The Sovol SV06 is a Chinese printer very clearly based on the Prusa i3 heritage. It's an excellent alternative to the MK3S+ and the firmware source and CAD designs are on GitHub. There are definitely budget-range 3D printers with an i3 heritage (probably not derived tightly from the Prusa design, a lot of them seem like the product of one engineer and a disassembled Ender 3), but the SV06 is for my money
the one to get, and it's a quarter of the price of an MK3S+, without the bizarre-in-2023 "preassembled" option that's table stakes for everybody else.
The bigger problem seems to be that the i3 printers are table stakes now, while Prusa engine seized up and forward progress went to pot. The Prusa XL is not vaporware but it's close and preposterously expensive, while the MK4 released without input shaping in their extremely customized port of Marlin. Those "Chinese knockoffs" are shipping Klipper-based printers, with SBCs, where you get that for free.
And then you have the Bambu printers, which are OSS-compliant where required (their slicer is a derivative of PrusaSlicer) but built an in-house OS (not actually that shocking, and almost certainly not pirated; 3D printers just aren't that hard) that has given them a printer that's conservatively 18-24 months ahead of everybody except maybe Prusa with the XL. I really don't like Bambu's patent saber-rattling, that sucks, but they just shipped a better mousetrap, too.
Open-source 3D printing is on the ropes because it isn't making stuff as good as the closed-source stuff. Not because of cheap cloners. I didn't want to buy a Bambu printer so held out for the Creality K1 (and they are being bad citizens, they haven't released their Klipper source) and it's not good, I waited for Prusa to sell me on a Prusa XL but to get one I'll be waiting until 2024 at the earliest and spending $500 on that "preassembled" option to boot, and...Bambu just sold me a P1S with an AMS for $1000 flat. C'mon.
