Summary of Reddit Comments on "nozzle for Bambu Lab PETG HF"
Overview of Bambu Filament
- Bambu Labs produces filaments that are different from stock SUNLU filament, as there are differences in chemistry or manufacturing processes.
- Profile tuning is important for quality prints, especially for functional pieces that require good layer adhesion and strength.
- SUNLU offers multiple versions of PLA, and not all PLA is equal.
PETG Printing
- PETG SUNLU profile on H2S provides excellent results with glossy objects and precision prints.
- PETG HF requires considerations like increasing bed temperature and ensure filament dryness for better adhesion.
- Textured PEI sheet may require a bed temperature of 75-80°C for proper adhesion when printing PETG.
Custom 3D Printing Profiles
- There is a suggestion for developing a GitHub repository for finely tuned custom profiles for various 3D printer models.
- Users share their experiences with SUNLU filaments and generic printer profiles, noting good results with minimal imperfections.
Nozzle and Printing Upgrades
- Upgrading to a copper block, all-metal heat break, and higher wattage heater can improve printing speed and quality.
- Using a CHT nozzle can increase printing speed and efficiency.
- Heat creep issues can arise if the extruder gets too hot during printing.
Tips for Troubleshooting Printing Issues
- Leveling the print bed and adjusting nozzle height are important for quality prints.
- Increasing bed temperature and retraction distance, as well as adjusting printing speed, can help with oozing and stringing issues.
- Cleaning the print bed with dish soap and water can improve adhesion.
Summary
Based on the Reddit comments, users recommend customizing printing profiles for PETG HF filaments from Bambu Labs and suggest upgrades to the printing setup for improved speed and quality. Attention to bed temperature, filament dryness, and nozzle adjustments can help address common printing issues like oozing and adhesion problems. Additionally, ensuring proper bed leveling and using appropriate cleaning methods can enhance printing results for various filaments.
