Runs really good for long hours with little down time. Once you have it running perfectly and all calibrated, the printer can run for months at a time without needing maintenance.
Some points of failure over time are the bearings (replace ~1-2 years of heavy use), fans (replaced hotend cooling fan once within the first year, replaced with a noctua and no problems since), plastic cooling fan shroud melting/deforming (replace once every 1-3 months, temperature of printer can cause this piece to warp faster), hotbed wires breaking (failed once after 4 years of almost constant use), PEI bed sheet (replaced 3 times, about once every year)
