Step-by-Step Math: How We Calculate PCTG (High Clarity Glycol) Length
Exact formulas and linear density substitutions for PCTG (High Clarity Glycol) (1.23 g/cm³) on a Bambu Lab (Reusable Spool) spool.
Deducting the verified 250g empty tare weight of the Bambu Lab (Reusable Spool) (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 PCTG (High Clarity Glycol) (1.23 g/cm³) yields the printable length.
Engineering Specifications & Troubleshooting Guide: PCTG (High Clarity Glycol) & Bambu Lab (Reusable Spool) Hardware
Factory-tested parameters, common failure modes, and workbench best practices.
- Dramatically higher optical clarity and notch impact resistance than PETG.
- The empty Bambu Lab (Reusable Spool) spool weighs 250g (Plastic). Flange outer diameter is 200mm with a 82mm hub bore.
Printing at PETG temperatures (<230°C) leading to weak layer adhesion.
