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.

- PCTG Technical Data Sheet (TDS)
- PCTG Material Safety Data Sheet (MSDS)
- PCTG Profile for Bambu Labs Printers

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

I bought four 1kg rolls of PCTG on the "AMS compatible" reel. When mounted as an external spool holder, it works fine and prints great on my new Bambu H2D printer. Great quality print, strong, and good looking.
Unfortunately, the reels are NOT truly AMS compatible -- at least not for the Bambu AMS 2 Pro came with my H2D Pro package. Two of the four reels are warped so don't track well in the AMS. But all have a round and slippery edge profile that the AMS rollers can get a good enough grip on to turn properly. So as the H2D is unloading filament and the AMS is commanded to roll the reel backwards to take up the ejected filament, it just slips. The reel doesn't turn and the filament ends up tangled inside the AMS housing.
Sorry for this negative review and I really hope that AF can source some better reels. I'd certainly be willing to pay the extra cost for them. Meanwhile, I've ordered four Bambu Labs refillable/split reels and it seems that I'll need to purchase or print/build a respooler to transfer the AF filament to them.
I'll end on a positive note: I received truly excellent support from the sales/shipping department. After placing my order, I realized it wouldn't get to my home before we were leaving for an extended vacation, so reached out to AF support. They were very helpful with holding and subsequently shipping once I'd returned. They even included some small sample rolls of other PCTG colors. The shipment arrived safely with all rolls still properly sealed.
Good quality and consistency.
Brian, thank you for the review!
The PCTG has printed great on my Bambu P1S with the profile from AF. Prints look great and seem stronger than PETG and the melting temperature is much better. I just wish there were more colors available. I need the higher melting temperature and like ABS for that but don’t want to print ABS because it causes cancer. It is slower to print than PLA but not by much and to get the higher temperature resistance it is great.
I'm on my third role and have enjoyed the strength and all benefits of a print in this material but it is EXTREMELY hygroscopic and I have to dry it for extended periods in between each print to prevent intense stringing
Taylor, thanks for taking the time to leave a review! Are you sure that the stringing is from the material absorbing moisture? We haven't experienced this issue in our internal testing, and the technical data for the material indicates that it should be relatively Non-hygroscopic relative to other common filament materials.
Would love to have some print profiles for the h2d
