thermally conductive filament?

[James Fackert]

does anyone know of any thermally conductive filament?   there are a number of thermoplastic resins that have enhanced thermal conductivity for led heat sinks etc...
Cool-Poly from celanese and Therma-Tech from Avient are examples. Both companies mention 3d printing but no filament suppliers.
the latter also has electrically conductive versions....

[Edward Simpson]

Probably not, thermal conduction like that would require a plastic to be a thermoset, otherwise it would melt when in use, so they're probably photo-polymer resins of some type for resin printing.

there are a number of high thermal conductivity  injection moldable thermoplastics available... just none in filament yet. except

TC Poly Ice9 rigid is available in filament but its $250 a kilogram and only 4 W/m-K

Covestro Makrolon TC210 is 0.3 to 1.4    W/(m-K)

CoolPoly from etec/celanese is  2 to 34  W/(m-K)

Therm-a-Tech from Avient is 10 to 20 W/(m-K) and is available in electrically conductive and in insulative

for reference aluminum is 150 to 230 W/(m-K)

It's interesting that some of them are rubbery...  One would think that a high percentage of fill with a ceramic or metal that conducts heat would make the material very rigid.
