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)

- 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.

Would love to have some print profiles for the h2d
So far so good. I purchased 1 roll of blank and 1 of gray. The black arrived fine but the vacuum bag on the gray was no sealed.
I've printed a few things with the black and they have come out nice.
Paul, I apologize that you weren't satisfied with the seal on one of your spools! We do our best to package our products so that they do not get damaged in shipping, and so that the bags stay sealed. However, we've learned the hard way that it is actually quite difficult to achieve this without significantly increasing the cost of shipping or our products.
I got 12 spools of PCTG. These came in paper thin cardboard boxes and 7/12 spools were no longer vacuum sealed because they got poked and let air in. These spools should be double boxed! It also took a long time to arrive, and it was in 2 shipments. The filament printed well and has a nice shiny finish melting at 270c. Parts ca.e out strong 💪
That shipping is horrible. Take pride in American made goods! Raise the price $1 for the thicker packaging. It matters
Ralph, thank you for taking the time to leave a review, we're glad you had good results with the filament! To address the issues you experienced with shipping: the vacuum bags being popped during shipment won't have any effect on the material; it would take weeks to months of open air exposure for the filament to absorb enough moisture for it to be problematic. Also, it's not as simple as increasing the price by $1 and buying thicker boxes. We shipped it in 2 packages to reduce shipping costs, if you wanted all 12 spools in a single box it would have likely been $30 to $45 for shipping. Using thicker boxes & more packing material would likely increase the cost per spool by closer to $2 to $3, and the simple fact is that the majority of customers simply are not willing to pay that. Please reach out to us at sales@americanfilament.us if you have any other questions or if we can assist you further!
Well packaged and quick delivery haven’t used it yet. Great customer service and quick responsive to support. Will purchase more.
Used this for an academic application. Very pleased with results, could use better instructions however for slicer settings.
