ROSA3D PET-G Filament 1.75mm 3kg Black

ROSA3D PET-G filament is a high-quality 3D printing material designed for reliability and ease of use. This 1.75mm black filament combines the user-friendly printing characteristics of PLA with the enhanced durability and chemical resistance of PET-G. Supplied in a large 3kg spool, it is an excellent choice for extended print jobs and high-volume production, ensuring consistent results with minimal shrinkage and excellent layer adhesion.

Advantages

The primary benefit of this PET-G filament is its versatility, offering a balance between mechanical strength and ease of processing. It is odourless during the printing process, making it suitable for indoor environments. The material is highly durable and can be post-processed through mechanical means such as drilling, sawing, grinding, or painting, allowing for extensive customization of finished parts. Furthermore, its high chemical resistance and structural integrity make it a dependable choice for functional components that require long-term stability.

Suitable for

• Functional prototyping
• Large-format 3D printing
• Mechanical parts and enclosures
• Decorative items such as lampshades

When it may not be suitable

This material may not be ideal for applications requiring extreme heat resistance, as it has a heat distortion temperature of 78°C. It is also not recommended for parts that will be subjected to high-impact stress or extreme outdoor conditions where UV degradation might occur over long periods.

How to use

To achieve optimal results, ensure your 3D printer bed is clean and properly levelled. Load the filament into your extruder and set the temperature between 220°C and 250°C depending on your specific printer model and print speed. The heated bed should be maintained between 60°C and 80°C to ensure proper adhesion. Adjust the cooling fan speed between 0% and 60% to balance detail quality and layer bonding. Store the filament in a dry place to maintain its properties, especially since it is supplied in a large 3kg format.

What to consider before purchase

• Ensure your 3D printer can accommodate a 3kg spool size.
• Verify that your printer's hotend is capable of reaching the required 220-250°C range.
• Check if your project requires food-safe certification, as the raw material is approved, but the final product requires independent testing.

Usage recommendations

For the best results with large-format prints, use a brim or raft to ensure stable adhesion to the build plate throughout the entire printing process.
