The F400 is one of the most reliable 3D printers on the market today. We have nine Fusion3 printers utilizing our F-Series platform, dedicated to printing the parts used to build new printers in our factory. These printers run between 16 and 24 hours per day, 5+ days per week. Two of these printers have been in service for over 10,000 hours of run time with only routine maintenance and some upgrades to the current configuration. This is equivalent to printing 10 hours per day, 5 days per week for 4 years.
