Prusament PETG Jet Black: A Deep Dive into Premium Printing

Prusament has carved out a reputation for high-quality filaments, and their PETG Jet Black is no exception. This filament promises consistent results and a beautiful, deep black finish. Let’s break down everything you need to know about Prusament PETG Jet Black, from its specifications to practical usage tips.

Detailed Specifications:

• Material: Polyethylene Terephthalate Glycol (PETG)
• Color: Jet Black (A true, deep black)
• Diameter: 1.75mm (Nominal)
• Diameter Tolerance: ± 0.02 mm (Industry leading precision)
• Recommended Nozzle Temperature: 230-250 °C (446-482 °F)
• Recommended Bed Temperature: 80-90 °C (176-194 °F)
• Recommended Printing Speed: 40-60 mm/s (Adjust based on printer and part complexity)
• Spool Weight: 1 kg (2.2 lbs)
• Spool Dimensions: Standard Spool Dimensions for easy fitment
• Density: 1.27 g/cm³
• Tensile Strength: 52 MPa
• Elongation at Break: 7%

Key Features and Benefits:

• Exceptional Dimensional Accuracy: Prusament is known for its tight tolerances, ensuring consistent extrusion and accurate prints. This is crucial for parts that require precise fitting.
• Good Strength and Durability: PETG offers a good balance of strength and flexibility, making it suitable for functional parts and prototypes. It’s more durable than PLA.
• Relatively Low Warping: PETG is less prone to warping than ABS, making it easier to print larger parts.
• Good Layer Adhesion: Proper temperature settings will result in excellent layer adhesion, creating strong, durable prints.
• Easy to Print: PETG is generally easier to print than ABS, making it a good choice for both beginners and experienced users.
• Food Safe (Conditionally): PETG is considered food-safe, but it’s essential to verify this for the specific Prusament PETG batch and your printer setup. Layer lines can harbor bacteria, so special post-processing might be needed for food-contact applications.
• Resistant to Chemicals and Moisture: PETG offers reasonable resistance to various chemicals and moisture, making it suitable for applications where exposure to these elements is possible.
• Consistent Color: Prusament is renowned for the consistency of its colors, ensuring that your prints are always the shade you expect.

Usage Tips for Optimal Results:

1. Drying: PETG is hygroscopic, meaning it absorbs moisture from the air. If your filament has been exposed to humidity, consider drying it before printing. Use a filament dryer or an oven at a low temperature (around 50°C or 122°F) for several hours.
2. Bed Adhesion: Proper bed adhesion is crucial for successful PETG prints. Clean your print bed with isopropyl alcohol or a dedicated bed cleaner. Use a PEI sheet, glass bed with adhesive, or painter’s tape for optimal adhesion.
3. First Layer Calibration: Ensure your first layer is properly calibrated. The nozzle should be close enough to the bed to create a slightly squished layer, but not so close that it restricts extrusion.
4. Temperature Settings: Start with the recommended nozzle and bed temperatures (230-250°C and 80-90°C, respectively) and adjust based on your printer and environmental conditions.
5. Fan Speed: Reduce fan speed to prevent warping and improve layer adhesion. Start with a low fan speed (20-40%) and increase it if necessary to improve bridging or overhangs.
6. Retraction Settings: Fine-tune your retraction settings to minimize stringing. Experiment with retraction distance and speed to find the optimal settings for your printer.
7. Print Speed: Reduce your print speed, especially for intricate details or overhangs. A slower print speed allows the filament to cool and solidify properly, resulting in better quality.
8. Enclosure (Optional): Using an enclosure can help to maintain a consistent temperature around the print, reducing warping and improving layer adhesion.
