Last Saturday, I attended a build event at Blu-Bin, the 3D printer store in Burlington Vermont. About 5 of us purchased Rostock Max kits from SeeMeCNC, and built them. Folks from SeeMeCNC were there to help, and had performed more than half of the assembly before we arrived. We finished it all up in about six hours.
I have purchased Solidoodles and Aluminati in the past. In each case, it took months and months to get delivery, and then another month or so to get the printers to actually print. Not so with the Rostock Maxes.
After assembly, calibration took about 30 minutes, after which the printers simply printed. Pretty amazing.
