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.
What Makes Filaments Abrasive
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 Sợi PA6-CF is optimized for reliable printing.
Nozzle Materials Compared
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.
Print Settings for Hardened Nozzles
Increase temperature by 5-10°C vs brass due to lower thermal conductivity. Extrusion may need 2-5% more flow. First layer settings may require adjustment.

3D Printing Nozzle Selection — Frequently Asked Questions
How long does a brass nozzle last with carbon fiber filament?
A standard brass nozzle lasts only 10-50 hours when printing with carbon fiber reinforced filament. Highly filled CF30 (30% carbon fiber) can destroy a brass nozzle in under 10 hours. Ruby nozzles can print thousands of hours with CF filament without measurable wear.
What nozzle material should I use for abrasive filaments?
Hardened steel nozzles (700-900 HB) provide 200-500 hours of reliable service with CF and GF filaments. Ruby nozzles (1500+ HB) offer essentially unlimited wear life for production environments.

Câu hỏi thường gặp
When is PTFE (Teflon) vs Peek — High-Performance Plastic Comparison for Extreme Environments a good option?
PTFE (Teflon) vs Peek — High-Performance Plastic Comparison for Extreme Environments is a good option when fast iteration, complex geometry, low tooling cost, or low-volume production is more important than molded-part unit cost.
What should be checked before choosing PTFE (Teflon) vs Peek — High-Performance Plastic Comparison for Extreme Environments?
Kiểm tra kích thước chi tiết, tính chất vật liệu, độ nhám bề mặt, dung sai kích thước, mức độ tiếp xúc với nhiệt, hướng tải trọng và xem có cần xử lý sau gia công hay không.
How does PTFE (Teflon) vs Peek — High-Performance Plastic Comparison for Extreme Environments compare with CNC machining?
In 3D có thể tạo ra các hình dạng phức tạp một cách nhanh chóng, trong khi gia công CNC thường mang lại độ bền cao hơn cho các bề mặt chính xác, dung sai chặt chẽ hơn và sử dụng vật liệu đạt tiêu chuẩn sản xuất.
What affects the cost of PTFE (Teflon) vs Peek — High-Performance Plastic Comparison for Extreme Environments?
Chi phí phụ thuộc vào vật liệu, thể tích in, thời gian in, độ dày lớp, việc tháo khung đỡ, hoàn thiện, kiểm tra và số lượng chi tiết trong mô hình.
