Pro PCTG, Transparent Atomic Purple, 1.75mm
3D-Fuel Pro PCTG is like PETG but better in many ways. It is tougher (up to 30x tougher than PETG), more chemically resistant, and has even greater clarity than PETG. This 1.75 mm filament is easy to use with a lower moisture absorption rate than PETG and doesn’t require an enclosure—print it just like PETG. The vivid Transparent Atomic Purple color and broad print-ability make it ideal for multi-color printing systems like the Bambu Lab AMS.
- Up to 30x tougher than PETG, thanks to PCTG’s flexible CHDM-based molecular structure, which enhances toughness and impact resistance.
- Better inter-layer adhesion, reducing weak points where impact forces might cause failure.
- More ductile and energy-absorbing, helping parts resist cracking or shattering under sudden loads.
- Greater clarity with a striking Transparent Atomic Purple hue, suitable for functional enclosures, visible mechanisms, or aesthetic accents.
- Lower moisture absorption than PETG, enabling reliable prints without needing an enclosure.
- Compatible with multi-color 3D printing systems like the Bambu Lab AMS, enabling vivid multi-material projects.
- 20-50% more impact resistant than PETG in real-world use, translating to longer-lasting housings, hinges, and protective parts.
Durability & Chemical Resistance
- Alcohols (IPA, ethanol, methanol): Resists prolonged exposure without degrading or cracking.
- Hydrocarbons (hexane, heptane, gasoline, mineral spirits): Better resistance to hydrocarbon solvents than PETG.
- 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, with typical cautions for very harsh conditions.
- Cleaning agents (bleach, degreasers, detergents): Withstands harsh cleaners without discoloration or damage.
- Oils and lubricants: Resists degradation from prolonged exposure to oils.
- Ketones (acetone, MEK): Performs better in low-concentration ketone environments.
AMS compatibility note: Since October 2023, 3D-Fuel products have been manufactured using AMS-compliant spools. Some colors may ship on older spool types; if you receive an older spool, leave the lid open a few millimeters when printing to ensure smooth feeding.
Print, Use, and Applications
- Ideal for protective housings for electronics or tools, drone parts and prop guard components, flexible clips, living hinges, and impact-resistant enclosures.
- Print profiles for Pro PCTG on the Bambu Lab printers are available here.
- AMS-friendly filament supports multi-color workflows, making it a strong choice for complex assemblies or color-critical projects.
