Meet 3D-Fuel Pro PCTG in Transparent Ice Blue, 1.75mm — a high-performance filament that combines PETG-like ease with a tougher, clearer, more chemical-resistant profile. Engineered for real-world use, it offers up to 30x the impact strength of PETG while maintaining excellent clarity and a lower moisture absorption rate, so you can print confidently without an enclosure.
Why Pro PCTG stands out
- Up to 30x tougher impact resistance than PETG, with improved ductility thanks to a cyclohexane dimethanol (CHDM) molecular structure that absorbs energy instead of cracking.
- Crystal-clear transparency—ideal for display-worthy enclosures, protective housings, and parts where visibility matters.
- Lower moisture absorption than PETG, enabling straightforward printing in typical room environments without special drying or enclosure requirements.
- Excellent inter-layer adhesion, helping parts withstand repeated stress, bending, and stress without premature failure.
- Well-suited for multi-color prints in systems like the Bambu Lab AMS, making color-mitoral designs smoother and more reliable.
In-prints what to expect
Prints with Pro PCTG behave similarly to PETG during setup—easy to print, with good layer bonding and strong performance in everyday environments. The material’s toughness makes it a practical choice for protective housings for electronics, drone components, hinges, clips, and other parts that see impact or bending.
Chemical resistance and durability
Pro PCTG offers superior resistance to a range of common substances compared to PETG, helping parts hold up under real-world exposures. Highlights include:
- Alcohols (IPA, ethanol, methanol): resists prolonged exposure without degradation or cracking.
- Hydrocarbons (hexane, heptane, gasoline, mineral spirits): better resistance to hydrocarbon-based solvents.
- Acids (acetic, citric, phosphoric): maintains structural integrity in mild to moderately concentrated acids.
- Bases (sodium hydroxide, potassium hydroxide, ammonium hydroxide): better resistance to strong alkalis.
- Cleaning agents (bleach, industrial degreasers): withstands harsh cleaners without discoloration or damage.
- Oils and lubricants (engine oils, hydraulic fluids): resists degradation with prolonged exposure.
- Ketones (acetone, MEK): performs better in low-concentration ketone environments.
AMS compatibility and spool considerations
Pro PCTG is designed to work with AMS-capable workflows. Since October 2023, many 3D-Fuel spools have been AMS-compliant, though you may still receive older spool types as colors move through inventory. If you encounter an older spool, it remains compatible with AMS—simply leave the lid open a few millimeters during printing.
