Step-by-Step Math: How We Calculate PP-GF (Glass Fiber Polypropylene) Length

Exact formulas and linear density substitutions for PP-GF (Glass Fiber Polypropylene) (1.05 g/cm³) on a Bambu Lab (Reusable Spool) spool.

Step 1: Subtract Empty Spool Tare Weight1000.0g net filament
Formula: W_net = W_total - W_tare
Calculation: 1250g - 250g = 1000.0g net filament

Deducting the verified 250g empty tare weight of the Bambu Lab (Reusable Spool) (Plastic) spool leaves the exact net plastic mass.

Step 2: Calculate 1.75mm Cross-Sectional Area0.024053 cm²
Formula: A = π × (d / 20)²
Calculation: 3.14159 × (0.0875)² = 0.024053 cm²

Volumetric cross-sectional area in square centimeters for 1.75mm filament.

Step 3: Calculate Printable Length in Meters & Feet396m (1299.2ft)
Formula: L = W_net / (ρ × A × 100)
Calculation: 1000g / (1.05 g/cm³ × 0.024053 cm² × 100) = 396m (1299.2ft)

Dividing net mass by the linear density of PP-GF (Glass Fiber Polypropylene) (1.05 g/cm³) yields the printable length.
