Step-by-Step Math: How We Calculate PLA (Polylactic Acid) Length
Exact formulas and linear density substitutions for PLA (Polylactic Acid) (1.24 g/cm³) on a eSun (Eco Cardboard Spool) spool.
Deducting the verified 135g empty tare weight of the eSun (Eco Cardboard Spool) (Cardboard) 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 PLA (Polylactic Acid) (1.24 g/cm³) yields the printable length.
Engineering Specifications & Troubleshooting Guide: PLA (Polylactic Acid) & eSun (Eco Cardboard Spool) Hardware
Factory-tested parameters, common failure modes, and workbench best practices.
- Keep cooling fan at 100% after layer 2 for crisp overhangs.
- Crack open enclosure door to prevent heat creep.
- The empty eSun (Eco Cardboard Spool) spool weighs 135g (Cardboard). Flange outer diameter is 200mm with a 54mm hub bore.
Printing too hot (>225°C) without adequate cooling, causing droopy bridges.
