All Metal Hotend Kit with Slotted Cooling Block for Wanhao i3

This is the Micro Swiss all metal hotend upgrade with redesigned cooling block for Wanhao i3, Wanhao i3 Plus and all other i3 clones with the following improvements:

  • Significantly better heat transfer
  • Slotted clamping system
  • No set screw to ding and damage thermal tube
  • Easier disassembling and easier adjustments
  • Precise control on bore diameter

This upgrade includes a modified thermal barrier tube, nozzle and cooling block. The thermal barrier tube is made from 2 different materials: The lower thermal break is made from stainless steel for low thermal conductivity, and the colder, upper part is made from aluminum, since it's better thermal conductivity is able to carry away any heat from the filament.

Micro Swiss' All Metal Hotend Features:

    • Allows you to print at much higher temperatures than with a PTFE-lined hotend 
    • Provides a more consistent melt zone, since the transition zone is located right at the heat break
    • When printing at high extrusion speeds, PTFE tube sometimes doesn't provide enough thermal conductivity to sufficiently melt the filament. With the all metal hotend kit, this problem is solved, since the filament is surrounded by thermally conductive material.


  • 1 0.40mm wear-resistant nozzle, made from 360 brass base material and plated with TwinClad XT coating
  • 1 thermal tube
  • 1 slotted cooling block
