@3dfuel: 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. Pro PCTG is an easy-to-use material with a lower moisture absorption rate than PETG and doesn't require an enclosure - use it just like PETG. The broad color selection and ease of printing make it an ideal choice for printing in a multi-color 3D printing system like the Bambu Lab AMS. Print Profiles Print profiles for Pro PCTG on the Bambu Lab printers are available here. Bambu AMS Compatibility Since October 2023, the 3D-Fuel Standard PLA has been manufactured using an AMS-compliant spool (more info on our spool sizes and weights). Since it takes time for some colors to move through our warehouse inventory, you may receive an older spool type. This is still compatible with the AMS, but you must leave the lid open a few mm. Pro PCTG is 20-50% More Impact Resistant Than PETG Key Reasons for Better Impact Toughness: Molecular Structure: PCTG contains cyclohexane dimethanol (CHDM), which gives it increased flexibility and toughness compared to PETG’s ethylene glycol structure. Flexibility vs. Brittleness: PCTG is more ductile, allowing it to absorb and dissipate energy during impact without cracking or shattering. Layer Adhesion: PCTG has better inter-layer bonding when 3D printed, reducing weak points in the structure where impact forces might cause failure. Real-World Implications: Drop Resistance: PCTG parts are less likely to crack, chip, or break when dropped, making it ideal for high-impact applications like enclosures or wearable devices. Repeated Stress: PCTG can endure repeated bending or sudden forces better than PETG, making it more suitable for hinges, clips, and flexible parts. Durability in Extreme Conditions: PCTG resists embrittlement under low temperatures, maintaining its toughness in environments where PETG may fail. Example Use Cases Benefiting from PCTG's Toughness: Protective housings for electronics or tools. Drone parts and propeller guards. Flexible clips, snap-fits, and living hinges. Impact-resistant containers or enclosures. Chemical Resistance Chemical Type Examples ...
