Hardened steel nozzles – for abrasive filaments
Hardened steel nozzles are the right choice if you regularly print with abrasive materials like carbon fiber, glass fiber, or glow-in-the-dark filaments. They are extremely wear-resistant and remain stable even at high temperatures.
Advantages of hardened steel nozzles
- Durable and robust
- Resistant to abrasive fillers
- Stable at high print temperatures
Limitations
- Lower thermal conductivity → higher print temperatures needed
- Surface less smooth → can slightly increase stringing
Recommended applications
- Carbon fiber-filled filaments
- Glass fiber-filled filaments
- Glow-in-the-dark or metal filaments
FAQ about hardened steel nozzles
When do I need hardened steel?
As soon as abrasive filaments are used – brass wears out too quickly here.
How do I recognize nozzle wear?
Irregular extrusion, fluctuating line width, "fuzzy" surfaces. Then the nozzle should be changed.
Can I print standard filaments with it?
Yes, but without the heat transfer advantage of brass – print times can be longer.
