Important Note

Carbon fiber or glass fiber versions of these filaments, such as PA-CF or PETG-CF, typically require hardened components like a hardened steel nozzle and hardened extruder gears.

Price note: Prices change a lot with sales, bundles, and refill vs. spool versions, so these numbers are best used as quick buyer expectations rather than exact store prices.
