Pro PCTG, LulzBot Green, 1.75mm from 3D-Fuel is a next-generation PETG alternative engineered for serious performance in real-world parts. This filament blends the printability you love in PETG with dramatically enhanced toughness, chemical resistance, and clarity, making it the smart choice for parts that see impact, bending, and exposure to solvents. Why Pro PCTG stands out
- Unmatched toughness: Pro PCTG delivers up to 30x greater impact resistance than PETG, so drops, knocks, and bending don’t translate into cracked or shattered parts. This makes it ideal for protective housings, drone components, and other high-stress applications. - Clearer, tougher, and more flexible: In addition to strength, Pro PCTG maintains excellent optical clarity and overall flexibility through its cyclohexane dimethanol (CHDM) chemistry, which gives it greater ductility and toughness than PETG. - Superior chemical resistance: Pro PCTG resists many common chemicals better than PETG, including alcohols, hydrocarbons, acids, bases, and cleaning agents, while preserving structural integrity where PETG may crack or soften. This broad chemical resistance unlocks use cases in harsh environments and with aggressive cleaners. - Printability you can trust: Like PETG, Pro PCTG is easy to print and forgiving in typical home or office environments. It has lower moisture absorption than PETG, reduces the need for enclosure cooling, and prints reliably on a wide range of printers. This makes multi-material or multi-color workflows—such as those with a Bambu Lab AMS—more practical and productive. - Broad color selection and compatibility: The line offers a wide color range, including the vivid LulzBot Green you’re choosing, while maintaining the same ease-of-use and performance benefits that printers expect from a premium PETG upgrade. What you can print with Pro PCTG
- Impact-ready enclosures and protective housings for electronics and tools.
- Drone parts, propeller guards, and other components that require toughness without sacrificing print quality.
- Flexible clips, living hinges, and snap-fit parts that endure repeated bending and stress.
- Impact-resistant containers and enclosures that resist mild chemical exposure. Printing and handling tips
- Print like PETG, with the added benefit of greater durability. The material is designed for straightforward printing on standard 3D printers without mandatory enclosures in many environments. - Expect strong inter-layer adhesion that helps parts withstand drop and impact forces, reducing weak points where failures could occur. - If you’re using AMS or other multi-color systems, Pro PCTG prints cleanly across multiple color streams, enabling bold, durable assemblies in mixed-color builds. Print profiles for Pro PCTG on the Bambu Lab printers are available here. - Moisture management: Pro PCTG absorbs moisture more slowly than PETG, but like all glycol-modified filaments, it will absorb moisture over time. This is a consideration for long-term storage and performance, especially in humid environments. AMS and spool compatibility notes
- Since October 2023, 3D-Fuel has shipped AMS-compatible spools for many colors, with a note that some colors may arrive on older spool types. Older spools are still AMS-compatible; you may need to leave the lid ajar by a few millimeters to maintain optimal feed. Specific product highlights
