My workhorse Prusa i3Mk2 has needed some repairs and small upgrades but it is still soldiering on. I've learned to do scheduled maintenance at least every Sunday. Here are some stats about its use during the Pandemic. Keep in mind this is just one of the half-dozen printers in use on this project by the printing team . All together we have gone through several 10 lb Filamatrix spools and at least that many 1 kg spools of Matterhackers. Early on, getting any PETG filament was a challenge with lead times of 4+ weeks. The Prusa reports 3.6 km of 1.75 mm PETG filament used . When it gets pushed out the 0.4 mm dia nozzzle, that's equal to 69 km of actual printed filament . That's 75,000 yards . About 750 football field-lengths of filament! PETG has a density of about 1.27 gm/cc. A 1 kg spool holds about 327 meters of 1.75 mm filament. A 10 lb spool holds 1490 meters of 1.75 mm dia filament. We've been purchasing 10 lb spools of clear PETG from Filamatrix due to their COVI
