| - | === Extruder nozzles === | ||
| - | The extruder nozzles are sensitive to heat treatment and mechanical strain.\\ If the nozzles or extruder barrels are clogged by congealed material, reheating during the normal production flow is utterly sufficient to clear them in most cases.\\ In case you want to change the material type or clogging is effected by foreign particles (i.e. dust grains dragged along with the filament), it is necessary to remove congealed material from the nozzles. The corresponding description can be found in the [[#Cleaning recommendation|cleaning recommendation]]. | ||
