- 📦 Use a reliable spool holder with smooth rotation for the 3 kg spool.
- 🧵 Store the filament in a sealed bag with silica gel after printing.
❓ FAQ
The 3 kg format is convenient for large models, serial printing and long jobs where fewer spool changes and lower risk of print interruption are important. Yes, PETG is suitable for housings, brackets, holders, adapters and other functional parts. It is stronger and more heat-resistant than standard PLA. Usually no. PETG can be printed on open-frame FDM/FFF 3D printers if the bed temperature is set correctly and the printer is protected from strong drafts. PETG can be prone to stringing. To reduce it, dry the filament, tune retraction, adjust nozzle temperature and optimize travel speed.Why is a 3 kg PETG spool convenient?
