My prints are of astronomical objects that contain fine filamentary structures. When they fail, they fail spectacularly and often after 10 hours. So far, the S5 is chugging along making a beautiful print. I've set up a file with a triple of this object that should take 5 days to print. I'm going out of town for work, so I'll ask someone to just check on it once a day. I am so happy with this so far.
I'm also using the TPLA that came with the printer. The object I am printing breaks easily, so I am hoping the TPLA holds up to the wear and tear of teenagers and middle school kids handling our stuff.
Unfortunately, I am already married and I think my husband might object to my love of the S5.
