American Filament PCTG 1.75mm, 1kg Spool, Obsidian Black AF

Print Settings

• Nozzle Temperature: 240 - 270°C
• Bed Temperature: 70 - 100°C
• Speed: 60 - 300 mm/s

Nozzle temperature can vary between 240-270°C depending on desired layer to layer adhesion vs part print quality. Higher nozzle temperatures will result in stronger parts, but may cause lower quality and/or increased stringing.

Part cooling can also vary depending on desired layer to layer adhesion vs part print quality. More cooling will result in better overhangs & bridging, but will decrease the ultimate layer to layer adhesion.

For Bambu Printers

We recommend using the Bambu Labs Gold Textured PEI build plate, or other aftermarket textured PEI build plates, for this material. 70°C should be sufficient for adequate build plate adhesion, going higher than this temperature may cause parts to adhere to the plate too well.

Recommended retraction length can vary between 0.8-1.2mm depending on the amount of stringing you experience.

It is recommended to lower your Top Surface print speed to 100-150 mm/s for higher top layer quality.

For Other Printers

The default retraction settings for PETG should be sufficient, but total retraction length may need to be increased slightly.
