PLA density and cost per gram

PLA density from Bambu Lab and Polymaker datasheets, the price per gram from the makers' own stores, and what a 310 g dragon costs in plastic.

Density, by datasheet

PLA BasicBambu Lab TDS1.24 g/cm³ · 335 m per kg
PolyLite PLAPolymaker1.17 g/cm³ · 355 m per kg

Metres per kilogram of 1.75 mm filament, worked out from each density: a denser plastic puts fewer metres on the same kilogram, so a slicer that reports length needs the density of the roll you load.

Price per gram, by maker

PLA Basic, $14.99 for 1000 gBambu Lab store$0.0150 a gram
Prusament PLA, $32.99 for 1000 gPrusa store$0.0330 a gram

What articulated dragon costs in plastic

The plastic is one line of a quote. Power, machine hours, your time and failed prints are the rest, and the cost calculator prices them all.
