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

American Filament PCTG is very similar to PETG with several distinct advantages. You could even call it a PETG+! Our PCTG is made with a PET-based copolyester specifically designed for professional grade 3D printing applications where easy processing and high toughness are critical.

Our PCTG is made with a PET-based copolyester specifically designed for professional grade 3D printing applications where easy processing and high toughness are critical.

This material features a unique self-bonding ability providing very high layer-to-layer adhesion; possesses a high melt strength ensuring an even flow during the 3D printing process; is more chemically resistant & stable than PETG, ABS, or ASA (making it suitable for a wide variety of applications); boasts unmatched impact strength & toughness; has lower moisture absorption than PETG (making it more shelf stable); and can be printed reliably without an enclosure.

Unlike PETG, the finish of PCTG can vary between matte and glossy depending upon the temperature and speed settings you choose. Try 240-245°C to get that matte finish!

Key Features:

• Unmatched Strength & Toughness: Higher compressive, tensile, and impact strength than many other PETGs.
• High-Temp: Glass Transition Temperature of 85°C.
• Professional-Grade Performance
• Low Odor
• Effortless Printing: Even flow rate & wide range of nozzle temperatures.
• Made in the USA: Manufactured with American quality you can trust.

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. For other printers: the default retraction settings for PETG should be sufficient, but total retraction length may need to be increased slightly.

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