Filament Selector
Answer nine questions about the part and your printer. The selector compares standard materials, HT-PLA and CF/GF-reinforced compounds while considering enclosure, hotend capability and nozzle wear.
1. Where will the part be used?
2. What temperature must it tolerate?
3. Does the part need to flex?
4. How will the part be loaded?
5. Is high stiffness and dimensional stability especially important?
CF/GF-reinforced filaments are often stiffer and more dimensionally stable, but they are not automatically tougher or better for every load case.
6. Do you have an enclosed build chamber?
7. Can your printer handle high-temperature engineering filaments?
This means a suitable hotend around 280 °C and above, plus an appropriate build plate and printing environment.
8. Do you have a wear-resistant / hardened nozzle?
Carbon-, glass- and similar fiber fillers are abrasive. A wear-resistant nozzle is strongly recommended for these compounds.
9. What matters most?
Important notes on HT-PLA and CF/GF
HT-PLA is not one universal material: some formulations reach higher heat resistance as printed, while others rely on annealing. The selector therefore avoids claiming one universal service temperature.
CF/GF is not a base polymer: fiber reinforcement modifies PLA, PETG, ASA, PA, PC and other materials. It can improve stiffness, dimensional stability and surface character, but also introduces abrasion and formulation-specific tradeoffs.
