Anatomy of a HotEnd – E3D

A breakdown of the components that make up a HotEnd: HeatSinks, HeatBreaks, HeaterBlocks, Heater Cartridges, Thermistors, DC Fans and Nozzles. A deep dive into the fundamentals of HotEnd material science: extrusion temperatures, die swell, pressure delay, heatcreep and HotEnd materials such as PLA and PEEK.
HotEnds, liquifiers, toolheads, extruders, shooty-squirty-plastic guns - just what are these and why are they so important to the 3D printers? What makes a good HotEnd, what makes a bad HotEnd, and what makes an excellent HotEnd? We at E3D have been making them since 2012, and we’ve learnt a thing or two.
