Goals

  • Use widely available materials
  • Mix several metals with different heat transfer coefficients to slow down convection.
  • Have a long and continous path where the transformation from solid to liquid takes places, in order to minimize turbulence and get a laminar output.
  • Get rid of PFTE/Peek in favor to make it more reliable/heat proof.
  • Easy to assemble design

First version conclusions

Aluminum was used for the heat sink. A stainless steel pipe was inserted inside as heat insulation for the filament. The brass nozzle goes inserted into an aluminum non threaded heating block.
