3D-Fuel Pro PCTG is a high-performance alternative to PETG, offering up to 30x the impact toughness, superior chemical resistance, and enhanced optical clarity. Designed for reliability and ease of use, Pro PCTG features a lower moisture absorption rate and does not require an enclosure—simply use it with the same convenience as PETG.
With a broad color selection and excellent printability, it is an ideal choice for multi-color 3D printing systems like the Bambu Lab AMS.
Print Profiles & Compatibility

Since October 2023, 3D-Fuel spools are manufactured to be AMS-compliant. If you receive an older spool style during our inventory transition, it remains compatible; simply leave the AMS lid slightly open (a few mm) during use. View spool specifications.
Pro PCTG: 20-50% More Impact Resistant Than PETG
Pro PCTG utilizes cyclohexane dimethanol (CHDM) in its molecular structure, providing increased flexibility and ductility. This allows parts to absorb energy and dissipate impact forces rather than cracking or shattering.
-
Drop Resistance: Ideal for protective housings, tool enclosures, and wearable devices.
-
Repeated Stress: High endurance for clips, snap-fits, and living hinges.
-
Extreme Conditions: Resists embrittlement in low temperatures where PETG may fail.
-
Superior Adhesion: Enhanced inter-layer bonding reduces structural weak points.

Low Moisture Absorption
Pro PCTG is significantly less hygroscopic than PETG, absorbing only 0.1–0.2% moisture by weight. This results in fewer print defects like stringing or bubbling and requires less frequent drying cycles. For optimal results, dry at 60-70°C for 4-8 hours.
