SUNLU 5KG PETG 3D Filament 1.75mm Neatly Wound High Toughness 3D Printing Spool Filament for FDM 3D Printer Materials Fast Ship

PETG Filament

PETG filament good toughness, high hardness, impact strength is 30 times more than PLA and the elongation at break of more than 50 time PLA.

Compatible printers must have heating device, can print models have strict requirement of toughness and strength, such as: pedant, also can print strongly heated-resistance and transparent models, such as: lampshde.

100% no bubble 3d printer material.

SUNLU 3D Printing Troubleshooting Guide

* Issue 1: Filament Surface Defects (Notches/Damage)

Root Cause: Physical damage during production or transportation.

Solution:

1. Immediately stop printing. Check the remaining filament on the spool for defects.
2. Contact SUNLU Support: Provide clear photos of the damaged section for replacement.

* Issue 2: Uneven Model Edges

Root Cause: Inconsistent extrusion due to filament diameter variation or moisture.

Solution:

1. Measure Filament Diameter:
Extract 1-meter filament and use calipers.
Gently clamp the filament at the center of the calipers (avoid excessive force).
Tolerance range: 1.75mm ±0.02mm.
Dry Filament: Use a filament dryer at 45-50°C for 4-6 hours if moisture bubbles are observed.

* Issue 3: Stringing/Oozing

Root Cause: Insufficient retraction, high nozzle temperature, or damp filament.

Solution:

1.Retraction Calibration:
Start with default settings: Retraction distance 5mm, speed 40mm/s.
Adjust within 20-100mm/s range through iterative testing.
2.Temperature Optimization: Reduce nozzle temperature by 5-10°C if stringing persists.

* Issue 4: Filament T

Root Cause: Improper storage or reloading of partially used spools.

Solution:

Locate the tangled section and carefully unwind it.
Preventive Measure: Always secure filament ends using the SUNLU filament clip or thread through the spool hole after use.

* Issue 5: Poor Bed Adhesion

Root Cause: Incorrect nozzle height, low bed temperature, or rapid cooling.

Solution:

Nozzle Height Calibration: Adjust to A4 paper thickness between nozzle and bed.
Temperature Adjustment:
Increase bed temperature (e.g., PLA: 60°C, PETG: 70°C).
Apply SUNLU bed adhesive or enable "Raft" in slicing software.

* Issue 6: Brittle Filament

Root Cause: Over-drying (>48hrs at high temps) or factory defects.

Solution:

For over-dried filament: Store in sealed bags with desiccant.
Contact SUNLU Support if brittleness occurs immediately after unsealing.

* Issue 7: Color Discrepancy

Root Cause: Lighting variations or minor batch differences.

Solution:

Compare under 6500K white LED light (industry standard).
Note: Natural color variations within ±5% are normal.
