About PEEK-GF Filament
PEEK-GF is a base plastic filled with chopped glass fiber. The fibers make parts stiffer and more dimensionally stable than the unfilled material, but they are abrasive: every glass fiber filament needs a hardened steel or other wear resistant nozzle. Read the glass fiber filament guide →
About the base material: PEEK is an extreme-performance engineering plastic used for aerospace, medical, and industrial parts that have to survive continuous heat around 260°C. It is not a material for a standard desktop printer: it needs an all-metal hotend rated to 400°C or higher and a heated chamber to print without warping or delaminating. Treat any PEEK listing as requiring purpose-built high-temperature hardware, not an upgrade path from PLA or ABS.
