Source discussion: RepRapMicron
“I bought a cheap, used, Bambu Lab A1 printer after reading a comment here on HN a few months ago saying that it was basically now "download and print". And it's just that. Not saying Bambu's practices are great: what I'm saying is that 3D printer now work better than inkjet 2D printers ever did.”
