Pro PCTG Galaxy Black (sparkly), 1.75mm from 3D-Fuel blends the best of PETG with enhanced toughness and clarity, delivering a filament that looks as bold as it prints. The Galaxy Black color adds a subtle, sparkly depth to every layer, making parts that stand out in both appearance and performance. Why Pro PCTG stands out
- Unmatched toughness: up to 30x tougher than PETG, giving you parts that resist drops, impacts, and repeated bending without cracking or shattering.
- Superior chemical resistance: handles common solvents and cleaning agents better than PETG, with notable resilience across alcohols, hydrocarbons, acids, bases, and oils.
- Clarity and color quality: maintains excellent optical clarity while delivering a vivid, consistent Galaxy Black finish.
- Printing ease: designed for straightforward printing with a lower moisture absorption rate than PETG, so you can print without enclosure requirements and still achieve reliable results.
- Ideal for multi-color systems: broad color options and predictable print behavior make Pro PCTG a natural fit for multi-spool, multi-color setups like the Bambu Lab AMS. What you can print with confidence
- Protective housings for electronics or tools that demand impact resistance.
- Drone components, guards, or enclosures where durability matters.
- Flexible clips, living hinges, and snap-fit parts that tolerate repeated use.
- Enclosures or cases that see regular handling, where both toughness and clarity matter. Printing and compatibility notes
- Print profiles for Pro PCTG on the Bambu Lab printers are available here.
- Bambu AMS compatibility: since October 2023, our spools are AMS-compliant for easy integration with AMS setups. Some colors may ship on older spool types; these are still AMS-compatible, but you may need to leave the lid open a few millimeters to maintain proper airflow and tension.
- Spool information: more info on our spool sizes and weights is available. Material and performance highlights
- Polymer family: PCTG, offering greater ductility and toughness than PETG.
- Impact resistance: designed to absorb and dissipate energy during impact, reducing the likelihood of cracks or breaks.
- Layer adhesion: improved inter-layer bonding for stronger, more durable prints.
- Environmental resilience: maintains toughness at lower temperatures, reducing embrittlement in challenging conditions. Chemical resistance overview (relative to PETG)
- Alcohols (IPA, ethanol, methanol): resists prolonged exposure without degrading.
- Hydrocarbons (hexane, gasoline, mineral spirits): better resistance to solvents commonly found in cleaning and lubricants.
- Acids (acetic, citric, phosphoric): maintains structural integrity in mild to moderately concentrated acids.
- Bases (alkalis like sodium/potassium hydroxide): better resistance to strong bases.
- Cleaning agents (bleach, degreasers, detergents): withstands harsh cleaners without discoloration or damage.
- Oils and lubricants: resists degradation from prolonged oil exposure.
- Ketones (acetone, MEK): performs better in low-concentration ketones. Additional details
- The product is part of the 3D-Fuel line and designed for reliability in professional and enthusiast-grade 3D printing.
- The Galaxy Black colorway provides a distinctive, sparkly aesthetic suitable for enclosures, visible hardware, and display pieces. Print with confidence, printing ease, and a striking finish with Pro PCTG Galaxy Black. For reference, the included color and finish come together with practical toughness and chemical resilience that set it apart from standard PETG filaments.
