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
- Does NOT Require Drying Before Use
- Effortless Printing: Even flow rate & wide range of nozzle temperatures.
- Made in the USA: Manufactured with American quality you can trust.

Print Settings
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.
DO NOT DRY AT TEMPERATURES OVER 60°C.

This is god quality filament. But, It is not even close to Gunmetal Gray. I didn't buy it for the name of the color though, rather by the color displayed on the website. It is more like Medium Gray.
Honestly, no real problems at all. I did have a bit of adhesion issues to start. (Prusa Mk4 MMU with a textured PEI print sheet), but swabbing the sheet with 91% isopropyl alcohol and spraying with a bit of hair spray fixed that).
Will definitely buy again.
The filament is great. The only issue is there is no profile for a Bambu Labs X2D. I modified the one for the P2S so it would work on my X2D printer. The only issue I have had is the filament is very runny at the start of the print but prints fine after that. It may be something with the profile.
Norman,
We apologize for the oversight on the X2D profile! It has been added to the downloadable profiles folder. We will also send it to you in an email.
We are so glad to hear you like the filament!
Best,
The AF Team
The PCTG that American Filament produces has become one of my favorite filament blends.
And the fact that is produced locally is a super plus.
Great filament, Has a nice finish.
