Tips
  • Bambu Studio shows estimated filament usage in the print preview
  • Add 5–10% buffer for failed prints or purge towers
  • When weighing remaining filament, subtract the empty spool weight (~200g for a standard 1kg spool)
  • Purge towers in multi-color prints can add 5–30g of waste material
