Density from the makers' datasheets and price per gram from their stores, for PLA, PETG, ASA, ABS and TPU, with what a print costs in plastic.

Printyard runs this arithmetic on your phone at the machine and on the web: every quote itemised, every roll to the gram, and a month with the fees and the failed prints already taken out.
