The F306 is one of the most reliable 3D printers on the market today. We have five F306 printers dedicated to printing the parts used to build new printers in our factory. These printers run between 10 and 16 hours per day, 5+ days per week. Two of these printers have been in service for over 8000 hours of run time with only routine maintenance and some upgrades to the current configuration. This is equivalent to printing 8 hours per day, 5 days per week for 4 years.
