Our take
Glow, wood, carbon-fiber, and glitter filaments chew through brass nozzles. A hardened steel set lasts far longer with abrasives. Keep a 0.4mm for general use and a 0.6mm for faster draft prints.
What we like
- Survives abrasive filament
- Cheap insurance
- Comes in multiple sizes
What to keep in mind
- Lower thermal conductivity than brass
- Overkill if you only print PLA
