This guide details the process of 3D printing an AR-15 lower receiver using Carbon Fiber Nylon, based on expert instruction from Hoffman Tactical. It covers essential filament preparation, specific printer hardware requirements, critical print settings, advanced slicing techniques for warp prevention, and post-processing steps. The instruction emphasizes the importance of material science knowledge for successful and durable firearm component printing.

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.
