great printer, if you enjoy upgrading and tinkering.. its not a "print perfectly out of the box" printer.. this is a complex build and took me about a week and a half to finish the default kit.. but I've been upgrading the printer since I bought it a year ago and now it prints faster and better than the fast "out of box" printers like Bambu. You are required to build your own firmware, but RatRig makes that fairly easy with their custom RatOS.
The Ratrig familly of 3D printers has openned a new era in the Professional 3D printing :
Only top notch components, perfectly harmonized by Ratos.
Printing fast at much higher quality, perfect layer bonding, lowering machine time and energy usage : better quality parts @lower costs, in no times.
