Steer clear of the K1 printers, I hear a lot of horror stories about them. Bambu may be coming out with something larger after the first of the year, how soon do you need it?My eldest, eighteen, and a wanna-be mechanical engineer has us convinced we need a 3D printer upgrade. He's presently using a Creality Ender 3 S1 Plus. His latest project is a RC car capable of hitting almost 40 mph. PLA parts keep breaking and he hopes more exotic filaments might be part of the solution. We're looking at Jason's latest (Bambu Labs X-1 Carbon), pondered their "industrial" variant X1E, or the Creality K1 Max. Any suggestions on an enclosed printer will be welcome.
