What owners report

  • “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.”

  • “[...] If you think you'll enjoy the experience of putting together a printer, get a prusa mk4 kit. I got the MK3s kit, and spent a week of evenings putting it together. [...]”

  • “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. [...] Hence why Thingiverse ran circles around them with a half broken site. 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.”

  • “While this is true and I own a Prusa MK4, they're so behind it's not even funny.”
