Nozzle Wear Calculator

How It Works

Brass nozzles are cheap but wear fast with abrasive filaments (carbon fiber, glass fiber). Hardened steel lasts 10-50x longer but conducts heat less efficiently (may need +5-10°C). Signs of worn nozzle: inconsistent extrusion, poor first layers, under-extrusion. Standard PLA barely wears brass; CF-Nylon destroys it in days.
