E3D Hot End Nozzle

/in , , /by

By Jessica Salazar – 3D Manufacturing

A hot end usually refers to the tip of the extruder. The hot end nozzle allows plastic and other material to melt. The hot end uses materials that can stand up to ~240C heat (for current thermoplastic extrusion). With no PEEK or PTFE the all-metal hot end can withstand temperatures that surpass the thermoplastic extrusion levels.

The heated part provides highly precise extrusion. The short distance between from cold filament to molten plastic reduces extrusion and jamming providing higher quality printing. The supplied thermistor has a maximum temperature of 300ºC and compatible with most 3D printing systems.

The Bowden that we are using ships with 800mm of tubing. 

Features:

  • No PEEK or PTFE
  • Reach Extremely High Temperatures
    300ºC with supplied thermistor
    >400ºC with thermocouple (additional electronics may be required)
  • CNC Machined Parts
    High precision
    High quality surface finish
    Aesthetically Pleasing 
  • Prints almost every material (including PLA)
  • Short Thermal Transition
    Improves extrusion accuracy
    Reduces ‘blobbing’
    Lowers extrusion force
    Less retraction required
  • Easy Mounting
    Plenty of community designed mounts (e.g. Thingiverse)
    Designed to fit in 16mm Groove Mount (i.e. J-Head)
