I would amortize it over 5 years. Plus maintenance cost for replacement parts. After 5 it may still work but your competitors upgraded and so must you.

This guy only made 50 sales and 3000 hours of print time. I'm actually somewhat confused at how they need to keep replacement parts stocked up for that kind of low runtime.

This is either a bad choice of printer, some kind of user error, or supreme bad luck.

I don't even know how to get a clog printing with PLA.
