\"3D<\/p>\n

When printing with standard filaments like PLA or PETG, a brass nozzle performs well. However, abrasive filaments containing carbon fiber, glass fiber, or metal particles will rapidly wear through brass, causing dimensional inaccuracies and eventual print failure.<\/p>\n

What Makes Filaments Abrasive<\/h2>\n

Carbon fiber reinforced filaments are highly abrasive with fiber hardness around 200 HB. Glass fiber is even harder at 500 HB. Metal-filled and glow-in-the-dark filaments also cause rapid wear. Our PA6-CF Filament<\/a> is optimized for reliable printing.<\/p>\n

Nozzle Materials Compared<\/h2>\n

Brass nozzles (hardness 55-100 HB) last 10-50 hours with CF filament. Hardened steel (700-900 HB) provides 200-500 hours of use. Ruby nozzles (1500+ HB) offer unlimited wear life for production environments.<\/p>\n

Print Settings for Hardened Nozzles<\/h2>\n

Increase temperature by 5-10\u00b0C vs brass due to lower thermal conductivity. Extrusion may need 2-5% more flow. First layer settings may require adjustment.<\/p>\n
