Step-by-Step Math: How We Calculate TPU 85A (Soft Flexible) Length
Exact formulas and linear density substitutions for TPU 85A (Soft Flexible) (1.18 g/cm³) on a Inland / Micro Center (Black Plastic) spool.
Deducting the verified 248g empty tare weight of the Inland / Micro Center (Black Plastic) (Plastic) spool leaves the exact net plastic mass.
Volumetric cross-sectional area in square centimeters for 1.75mm filament.
Dividing net mass by the linear density of TPU 85A (Soft Flexible) (1.18 g/cm³) yields the printable length.
