Tim Ruffner of 3D Printing and Production recently ran a test of nearly 10 separate 3D Printers that he recently got into the shop. He was comparing speed, visual appearance, and dimensional accuracy. Guess which printer won for dimensional accuracy. That's right the Mason Metal-end printer. Would have won it all if the filament wasn't wet.
Of the printers in Tim's group he has had the Mason the longest. It has been supporting his Covid-19 efforts reliably from the very beginning helping to making face shields
