How Much STRONGER is Carbon Fiber Filament? And is it better?
Hoffman Tactical provides an in-depth analysis of carbon fiber (CF) PETG filament for 3D printing, comparing its strength and properties to standard PETG and PLA. The expert assessment highlights that while CF PETG offers increased stiffness and a 25% tensile strength improvement horizontally, it also becomes more brittle. For applications like firearm lower receivers, the recommendation leans towards non-filled plastics such as PLA+ or 3D870 PLA due to their better balance of strength, durability, and heat resistance. Printing with CF filament necessitates a hardened steel nozzle.
