Step-by-Step Math: How We Calculate PETG (Polyethylene Terephthalate Glycol) Length
Exact formulas and linear density substitutions for PETG (Polyethylene Terephthalate Glycol) (1.27 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 PETG (Polyethylene Terephthalate Glycol) (1.27 g/cm³) yields the printable length.
Engineering Specifications & Troubleshooting Guide: PETG (Polyethylene Terephthalate Glycol) & eSun (Eco Cardboard Spool) Hardware
Factory-tested parameters, common failure modes, and workbench best practices.
- Use glue stick on smooth PEI to prevent PETG from tearing bed coating.
- Drying at 65°C eliminates stringing.
- The empty eSun (Eco Cardboard Spool) spool weighs 135g (Cardboard). Flange outer diameter is 200mm with a 54mm hub bore.
Running 100% part cooling fan which drastically weakens PETG layer adhesion.
