Key Features

• High-quality PLA filament: The recommended nozzle temperature is about 210-220°C. With quality and consistency in mind, stronger toughness with low shrinkage and better layer adhesion. Meet your needs for functional print projects. (Using tips: Please pass one end of the filament into the fixing hole to avoid being entangled after finishing your printing.)
• Dimensional Accuracy & Consistency: PLA filament. Self-adaptive control system in the manufacturing guarantee the 1.75 mm diameter, dimensional tolerance: +/- 0.02mm, 1 kg spool (2.2lbs) net weight.
• Clog-Free & No Bubble: PLA is vacuum sealed with desiccant to protect the filament from moisture to achieve high-precision printing.No clogging and bubble-free.
• Less-tangle and Easy to Use: Auto-mechanical winding to make sure the wire is neatly arranged.Recommended PLA filament extrusion/nozzle Temperature 210℃ - 220℃
• Wide Compatibility: Works and Compatibleperfectly with all common 1.75mm FDM 3D printers.

Setup and Handling

Proper handling of your filament is crucial for successful prints and to maintain its quality. Always handle the filament with clean hands and avoid touching the filament directly to prevent contamination.

Securing Filament End

After each use, ensure the filament end is securely fixed into the designated holes on the spool. This prevents the filament from unraveling and tangling, which can lead to printing issues.

Dimensional Accuracy

Comgrow PLA filament maintains a consistent 1.75mm diameter with a tight tolerance of +/- 0.02mm. This precision ensures smooth feeding through your 3D printer's extruder and consistent print quality.

Operating Instructions

For optimal results with Comgrow PLA filament, adhere to the following printing guidelines:

• Recommended Nozzle Temperature: 210°C - 220°C
• Recommended Bed Temperature: 45°C - 60°C
• Printing Speed: 40-70mm/s
• Retraction for Bowden Extruder: 4-8mm
• Retraction for Direct Drive: 0.5-1mm

Maintenance and Storage

To ensure the longevity and performance of your Comgrow PLA filament, proper maintenance and storage are essential. PLA can absorb moisture from the air, which can lead to printing issues such as bubbling, stringing, and reduced print quality.

Preventing Moisture Absorption

The filament is vacuum-sealed with desiccant to protect it from moisture during shipping and initial storage. Once opened, it is recommended to store the filament in a dry, cool place, ideally in an airtight container with desiccant packets. This will help maintain its optimal printing properties.

Troubleshooting

Encountering issues during 3D printing is common. Here are some common problems and potential solutions when using PLA filament:

Clogging

• Cause: Incorrect temperature settings, dust/debris on filament, or heat creep.
• Solution: Verify nozzle temperature is within the recommended range (210-220°C). Ensure filament is clean and stored properly. Check for proper cooling of the hotend.

Poor Adhesion

• Cause: Incorrect bed temperature, unlevel print bed, or dirty print surface.
• Solution: Set bed temperature to 45-60°C. Level the print bed accurately. Clean the print surface with isopropyl alcohol.

Stringing/Oozing

• Cause: Too high printing temperature or incorrect retraction settings.
• Solution: Reduce nozzle temperature in 5°C increments. Adjust retraction distance and speed (e.g., 4-8mm for Bowden, 0.5-1mm for Direct Drive).
