Pro PCTG in Transparent Ultramarine Blue, 1.75mm — a high-performance 3D-Fuel filament engineered to outperform PETG in real-world prints. It offers exceptional toughness, chemical resistance, and clarity, with simpler handling that suits both hobbyists and professionals.
Unmatched toughness, dependable printability
- Up to 30x tougher than PETG in impact performance, making parts that survive drops, knocks, and repeated use.
- 20–50% more impact resistant than PETG on typical tests, helping parts stay intact in high-stress applications.
- Flexible, ductile molecular structure (CHDM) improves energy absorption during impact and reduces cracking or shattering.
- Excellent layer adhesion, delivering stronger prints with fewer weak points where failure can begin.
- Maintains toughness in cold environments where some PETG formulations embrittle.
Clear, durable, and easy to print
Pro PCTG combines the clarity you expect with robust chemical resistance and a smoother print experience. It has a lower moisture absorption rate than PETG, so you can print with minimal enclosure requirements and straightforward post-processing. The result is transparent-looking parts that stay strong in real-world use.
Chemical resistance overview
- Alcohols (IPA, ethanol, methanol): resists prolonged exposure without cracking.
- Hydrocarbons (hexane, heptane, gasoline): better resistance to hydrocarbon-based solvents.
- Acids (acetic, citric, phosphoric): maintains structural integrity in mild to moderately concentrated acids.
- Bases (alkalis such as sodium/potassium hydroxide): better resistance to strong bases.
- Cleaning agents (bleach, degreasers, detergents): withstand harsh cleaners without discoloration or damage.
- Oils and lubricants (engine oils, hydraulic fluids): resists degradation from prolonged oil exposure.
- Ketones (acetone, MEK): performs slightly better in low-concentration ketone environments.
Printing and compatibility
Designed to work smoothly with multi-color setups like the Bambu Lab AMS, Pro PCTG prints reliably without an enclosure, and offers excellent inter-layer bonding that helps multi-part assemblies stay solid over time. If you’re printing with AMS colors, you’ll appreciate the consistent flow and the ability to swap colors mid-build with minimal fuss.
AMS compatibility notes: Spools are AMS-compatible; some colors may arrive on an older spool type. If so, you can leave the lid ajar by a few millimeters to maintain airflow and print quality. Since October 2023, the 3D-Fuel Standard PLA+ has used an AMS-compliant spool, and we provide details on spool sizes and weights for planning your workflow. This practicality extends to Pro PCTG spools as well.
Ideal use cases
- Protective housings for electronics or tools that benefit from extra impact resistance.
- Drone components, propeller guards, and other high-stress parts.
- Living hinges, flexible clips, and snap-fits that tolerate repeated bending.
- Impact-resistant enclosures and protective cases for outdoor or rugged environments.

| Chemical Type | Examples | PCTG Advantage | PETG Limitation | Comparison (CRR) |
|---|---|---|---|---|
| Alcohols | Isopropyl alcohol (IPA), ethanol, methanol | Resists prolonged exposure without degrading or cracking. | Degrades or stress cracks with high alcohol concentrations over time. | 1.8 |
| Hydrocarbons | Hexane, heptane, gasoline, mineral spirits | Better resistance to hydrocarbon-based solvents. | Softens or weakens when exposed to hydrocarbons. | 2.0 |
| Acids | Acetic acid, citric acid, phosphoric acid | Maintains structural integrity in mild to moderately concentrated acids. | Degrades faster in acidic environments at higher concentrations. | 1.4 |
| Bases (Alkalis) | Sodium hydroxide, potassium hydroxide, ammonium hydroxide | Better resistance to strong alkalis. | May crack or degrade when exposed to strong bases. | 1.33 |
| Cleaning Agents | Bleach (sodium hypochlorite), industrial degreasers, detergent solutions | Withstands harsh cleaning agents without discoloration or damage. | Discolors, cracks, or loses properties with harsh cleaning agents over time. | 1.5 |
| Oils and Lubricants | Engine oils, hydraulic fluids, cutting oils | Resists degradation from prolonged exposure to oils. | Absorbs oils over time, potentially leading to swelling or weakening. | 1.6 |
