Upgrade your material catalog with 3D-Fuel Pro PCTG—the next-generation polymer that behaves like PETG but outperforms it in nearly every mechanical property. Engineered for maximum durability, Pro PCTG delivers up to 30x the impact toughness of standard PETG, exceptional optical clarity, and enhanced chemical resistance, all while remaining incredibly easy to print.
Thanks to its lower moisture absorption rate, Pro PCTG does not require a heated chamber or complex enclosure setup. Its ease of printing and broad color palette make it the ultimate high-strength choice for multi-color setups like the Bambu Lab AMS system.
Bambu AMS Compatibility Note: This product features standard AMS-compliant spools. If you happen to receive an earlier legacy spool from our warehouse inventory, it remains fully compatible with the AMS—simply leave the AMS lid propped open by a few millimeters during operation. Official Bambu Lab print profiles are available here.
Advanced Molecular Structure: Formulated with cyclohexane dimethanol (CHDM), giving the polymer outstanding flexibility and impact dissipation compared to the standard ethylene glycol found in PETG.
Ductility vs. Brittleness: Rather than cracking under sudden load, Pro PCTG flexes and absorbs energy, making it highly drop-resistant.
Less Drying Needed: With a moisture absorption rate of just 0.1–0.2% by weight (compared to PETG's 0.3%), Pro PCTG is highly forgiving in humid environments, significantly reducing stringing, bubbling, and surface defects.
Long-Term Stability: Maintains its physical and mechanical properties over time without degrading or becoming brittle in high-humidity settings.
