Description Hardened nozzles are the best type that do every kind of 3d printing really well. 0.4mm nozzles are the default, but 0.6mm nozzle diameter is recommended for Carbon Fiber, Glass, & Wood based filaments as it reduces chances of blockages & under-extrusion over longer prints. These nozzles also double or triple your effective throughput, thereby allowing your 3d prints to be completed much faster, usually 2 to 3 times faster! Simply unscrew the existing nozzle & screw the new one on, easy. Please remember to always heat your hot end before removing your nozzle. Please choose your size, else we will send a 0.4mm by default.
