Assumptions and limitations
Uniform solid circular filament. Enter density from the actual material specification and net filament mass excluding the spool. Diameter variation, moisture and filled/foamed material differences are not inferred. Example density 1.24 g/cm³ is illustrative. A 1.75 mm filament has a cross-section of approximately 2.405 mm².
