the print bed is pretty small, but it still works. I have to resize a few things. calibration is needed often, but it isnt that hard. I would use cura for the prints. hatchbox is good for this and the filament will last about three months give or take. you have to be creative and careful with the machine or you could find it very frustrating. it comes pre built right out of the box. I print things on a daily basis and come to a couple issues. taking off supports is hard and it seems to like printing with the printjob stuck to the nozzle. it comes with an stl file and enough filament to print it, (if you dont stop it). ALWAYS read the print settings, ALWAYS be careful, and most of all, have fun printing!
