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
600 of our reusable shields is roughly equal to 18,000 disposables! That 30-day/shift use number is holding up in the field. We have now shipped to physical therapists, teachers, speech therapists, orchestra members, church workers, social workers, etc in TX, OH, NY, CO, and other states. Demand for face shields has slowed as there is now a glut of disposable shields available, both from China and domestically. But we are still providing them to HCP such as much of the Pediatric ED at the UofU. We have great stock of all the parts and materials so please let us know if you need shields or replacement parts. Since early August I've been able to keep up with demand with my own printers and give the 3D print team a rest. Some printer stats are coming up in the next post.
