Introduction

Often times the nozzle on the 3D printer becomes clogged or broken and needs to be replaced. You will need to repair your nozzle when you have prints that are consistently failing. You need a clean nozzle to be able print smooth and even surfaces. You will need heat resistance gloves to do this repair because the nozzle will be in excess of 250 degrees Celsius.
