1. Introduction to SUNLU PETG Filament
SUNLU PETG (Polyethylene Terephthalate Glycol) filament combines the best characteristics of both PLA and ABS 3D printer filaments. It offers the ease of use found in PLA, alongside the durable strength and impact resistance typically associated with ABS. This makes it a versatile material suitable for a wide range of 3D printing applications.

2. Caratteristiche del prodotto
- PETG Filament Advantages: Combines the benefits of PLA (easy to use) and ABS (durable strength).
- 1.75mm Filament Diameter: Dimensional accuracy of +/- 0.02mm ensures wide compatibility with most 1.75mm FDM 3D printers.
- SUNLU Neat Spool Design: Spool Diameter: 8.00", Spool Width: 2.50", Spool Hub Hole Diameter: 2.20". Designed to fit many FDM 3D printers.
- Individually Vacuum-Sealed: Each 1kg spool is individually vacuum-sealed with desiccant to prevent moisture absorption and ensure optimal print quality.

3. Setup: Assembling the Refill Spool
The SUNLU PETG filament comes as a refill, designed to be used with a reusable spool. Follow these steps to properly assemble your filament onto the spool:
- Separate the Spool Sides: Gently pull apart the two halves of the reusable spool.
- Preparare la ricarica: Unpack the new filament refill. Do NOT remove the plastic straps holding the filament together at this stage.
- Load Refill Filament: Place one side of the spool onto the refill filament. Ensure the positioning hole on the refill aligns with the notch on the spool hub.
- Combine Spool Halves: Align the triangular marks on both sides of the spool and press them together firmly. Rotate one side clockwise until it clicks and locks into place.
- Remove Plastic Straps: Once the spool is securely assembled, carefully remove the plastic straps from the filament.
- Ensure Tightness: Press the filament hard to ensure it is close to the spool, leaving no gap between the filament and the spool.

4. Operating Instructions: Recommended Print Settings
For optimal results with SUNLU PETG filament, we recommend the following print settings. These are general guidelines and may require slight adjustments based on your specific 3D printer model and environmental conditions.
- Temperatura dell'ugello: 240-260°C
- Temperatura del letto: 65-75°C
- Velocità di stampa: 50-200 mm/s

5. Manutenzione
Proper maintenance of your filament ensures consistent print quality and extends its lifespan:
- Magazzinaggio: Always store unused filament in its original vacuum-sealed packaging or in an airtight container with desiccant. This prevents moisture absorption, which can lead to printing issues like stringing and bubbling.
- Essiccazione: If you suspect your filament has absorbed moisture (e.g., it produces popping sounds during printing, excessive stringing, or poor layer adhesion), consider drying it using a filament dryer or a low-temperature oven according to PETG drying guidelines.

6. Risoluzione Dei Problemi
Encountering issues during printing is common. Here are some tips for common problems with PETG filament:
- Excessive Stringing: PETG can be prone to stringing. Try reducing your print temperature in 5°C increments, increasing retraction distance, or increasing retraction speed. Ensure your filament is dry.
- Scarsa adesione degli strati: If layers are not bonding well, increase your print temperature slightly (5°C increments) or slow down your print speed. Ensure your bed temperature is within the recommended range and that your print surface is clean and properly prepared.
- Deformazione: Ensure your heated bed is at the recommended temperature and consider using an enclosure for your printer to maintain a stable ambient temperature.
