Hot Flow is our term for filament-based materials which are deposited at over 150°C, depending on the head.

Note that at present, our Hot Flow heads work with 1.75mm filament (actually, 1.6mm to 1.9mm), but not 3mm filament.

The following materials can be printed from Hot Flow heads.

  • ABS (Acrylonitrile Butadiene Styrene)
    • Flame Retardant ABS
    • ABS - PC Alloy
    • Conductive ABS
    • Smart ABS
  • BendLay
  • Flex 45
  • HIPS (High-Impact PolyStyrene)
  • LayBrick

The following table compares the properties of the various Hot Flow heads, including which heads are recommended for which materials. The MK1 heads drive matieral from one side, with a spring-loaded bearing system to maintain pressure and positioning. The MK2 heads drive the material from both sides, and are designed for more flexible filaments.

Settings for Hot Flow Heads - Version 2.x

This is for Repetrel version 2.x. Hydra units, and other units shipping as of summer 2017 will have version 3.x, and should consult the version 3.x tables, below. All units should be upgraded to 3.x when it is available.

Some settings for the MK-Type heads (like temperature, prime/unprime values) will vary, depending on what material you are printing with. Nozzle diameter should accurately reflect what nozzle you have loaded (0.5mm is default) AND what path width you sliced for (recipe path or extrusion width should be nozzle diameter plus 10%). Having said that, here are our default shipping settings:
