Pro PCTG, Natural, 1.75mm is 3D-Fuel’s advanced filament that takes PETG’s practicality and elevates it with greater toughness, chemical resistance, and clarity. It’s designed for reliable, high-performance prints straight from the spool—without needing an enclosure.
- Up to 30x tougher than PETG, delivering parts that resist cracking and shattering on impacts.
- 20–50% more impact resistant than PETG, thanks to a molecular structure that enhances flexibility and energy absorption.
- Better inter-layer adhesion, reducing weak points and improving part durability under repeated stress.
- Greater clarity than PETG, making it suitable for visibility-focused housings and enclosures.
- Lower moisture absorption than PETG, enabling straightforward printing without the need for an enclosed chamber.
- Easy to use in a wide range of printers, with broad color selection and compatibility for multi-color printing in systems like the Bambu Lab AMS.
- Print profiles for Pro PCTG on the Bambu Lab printers are available here, helping you achieve consistent results on AMS setups.
- AMS-compatible spool history since October 2023; you may receive an older spool type from time to time. It remains AMS-compatible, but you should leave the lid open a few millimeters to maintain proper performance.
- Ideal for demanding, high-impact applications such as protective housings for electronics or tools, drone parts and propeller guards, flexible clips, living hinges, and impact-resistant containers or enclosures.
Chemical resistance at a glance
- Alcohols (IPA, ethanol, methanol): Resists prolonged exposure without degrading or cracking.
- Hydrocarbons (hexane, heptane, gasoline, mineral spirits): Better resistance to hydrocarbon-based solvents.
- Acids (acetic acid, citric acid, phosphoric acid): Maintains structural integrity in mild to moderately concentrated acids.
- Bases (alkalis such as sodium hydroxide, potassium hydroxide): Better resistance to strong alkalis.
- Cleaning agents (bleach, degreasers, detergents): Withstands harsh cleaning agents without discoloration or damage.
- Oils and lubricants: Resists degradation from prolonged exposure to oils.
- Ketones (acetone, MEK): Performs better in low-concentration ketone environments.
With its combination of toughness, chemical resilience, and printability, Pro PCTG Natural 1.75mm is well suited to functional parts that demand reliability and clarity. Whether you’re prototyping protective housings, crafting durable living hinges, or building multi-color assemblies for your AMS workflow, this filament is engineered to perform part after part.
