How to Print with colorFabb_HT Filament

Printing with colorFabb_HT requires specific settings and preparation to bring out the best in this high-performance material. Here’s a breakdown of the recommended setup and print parameters.

1. Recommended Printer Setup

All-Metal Hotend

colorFabb_HT requires high temperatures, typically between 250°C and 280°C, which may damage standard PTFE-lined hotends. Using an all-metal hotend is essential to handle the high printing temperatures required for colorFabb_HT without degrading over time.

Hardened or Ruby Nozzle (Optional)

While colorFabb_HT is not as abrasive as some carbon fiber or metal-filled filaments, using a hardened or ruby nozzle can be beneficial if you plan to print with other abrasive filaments alongside colorFabb_HT. A standard brass nozzle will work fine but may wear out faster over time with other high-performance materials.

Heated Bed

A heated bed is crucial for printing colorFabb_HT. Set the bed temperature between 100°C and 110°C to ensure proper adhesion and prevent warping, especially for larger prints.

Enclosure (Recommended)

Printing in a controlled environment can significantly improve the quality of colorFabb_HT prints. If possible, use an enclosed printer or add an enclosure around your open printer to maintain consistent temperatures and prevent drafts, which can cause warping or layer adhesion issues.

2. Optimal Temperature Settings

Extruder Temperature

The recommended extruder temperature for colorFabb_HT is between 250°C and 280°C. Start at 260°C and adjust based on your printer and the specific requirements of your model. If you encounter layer adhesion issues, try increasing the temperature incrementally. Avoid going below 250°C, as this can lead to under-extrusion and poor layer bonding.

Bed Temperature

A bed temperature of 100°C to 110°C is ideal for colorFabb_HT. This helps the first layer adhere properly, reducing the risk of warping on larger prints. If the bed struggles with adhesion, consider adding a thin layer of glue stick or painter’s tape to improve grip.

3. Print Speed and Retraction Settings

Print Speed

colorFabb_HT benefits from slower print speeds, as it ensures consistent extrusion and high-quality layer adhesion. A speed of 30-50 mm/s is recommended. If you prioritize detail over speed, try starting at the lower end of this range and gradually increase if desired.

Retraction Settings

Use a retraction distance of 2-3 mm with a retraction speed of 25-35 mm/s for direct-drive setups. For Bowden setups, a longer retraction distance (4-6 mm) may be necessary. Proper retraction settings help prevent stringing, but excessive retraction can lead to clogging with high-temperature filaments like colorFabb_HT.

4. Layer Height and Extrusion Settings

Layer Height

For standard prints, a layer height of 0.2 mm is a good starting point with colorFabb_HT, balancing print speed and quality. For fine details, you can go as low as 0.1 mm, and for thicker, functional parts, 0.3 mm is an option.

Extrusion Multiplier (Flow Rate)

The extrusion multiplier (or flow rate) should generally be set at 100%. However, if you experience gaps between layers, try increasing it to 105%. Conversely, if you see excess material or over-extrusion, reduce the flow slightly.

Troubleshooting Common Issues with colorFabb_HT

Issue: Warping and Poor Bed Adhesion

Solution: Ensure your bed temperature is set between 100°C and 110°C. A brim or raft can also help anchor the print and prevent warping. If the issue persists, consider using an enclosure to maintain a consistent temperature around the print.

Issue: Stringing or Oozing

Solution: Lowering the extruder temperature slightly and adjusting the retraction distance can help reduce stringing. Increase the retraction speed if necessary, but avoid excessive retraction to prevent clogs.

Issue: Under-Extrusion

Solution: Under-extrusion can be resolved by increasing the extruder temperature in 5°C increments until you find the optimal setting for your printer. Additionally, ensure the filament path is clear and that the nozzle is not partially clogged.

Issue: Layer Delamination

Solution: Layer separation can occur if the print temperature is too low or if there is insufficient adhesion between layers. Increase the extruder temperature and consider printing in an enclosed environment to reduce cooling too quickly.

Tips for Achieving the Best Results with colorFabb_HT

  1. Dry the Filament: Like many high-performance filaments, colorFabb_HT is hygroscopic, meaning it absorbs moisture from the air. Store it in a dry, sealed container with desiccant packs and consider drying it in a filament dryer if it has been exposed to humidity.
  2. Use an Enclosure for Large Prints: Enclosing your printer helps maintain a stable temperature around the print, reducing the chances of warping or layer separation.
  3. Optimize Cooling: colorFabb_HT generally benefits from low or no cooling to improve layer adhesion. Set the fan speed to 0-20% depending on the size of your print and the detail required.
  4. Proper Bed Adhesion: A clean and properly leveled bed is essential for printing colorFabb_HT. For additional adhesion, consider using a glue stick or PEI sheet if you have trouble with lifting edges.

Recommended Slicer Settings for colorFabb_HT

For slicers like Cura, PrusaSlicer, or Simplify3D, use the following recommended settings and adjust as needed for your specific printer setup:

  • Extruder Temperature: 250°C - 280°C
  • Bed Temperature: 100°C - 110°C
  • Print Speed: 30 - 50 mm/s
  • Layer Height: 0.2 mm (adjust based on desired detail)
  • Retraction Distance: 2 - 3 mm (for direct drive setups)
  • Retraction Speed: 25 - 35 mm/s
  • Cooling Fan: 0 - 20%

colorFabb_HT is a high-performance filament that brings strength, durability, and heat resistance to your 3D printing projects. By following these tips and using the recommended settings, you can achieve reliable, professional-quality prints that withstand challenging environments. Whether you’re creating functional prototypes, automotive parts, or heat-resistant enclosures, colorFabb_HT offers the versatility and resilience you need for demanding applications.
