I would be interested in testing the material. I have two extruders setup and one kit I am working on. I would extrude the material for a few dollars a test as the nozzles do wear and new ones would be needed occasionally depending on the needs of filament for consistance diameter.

Do you know the MFI? I could estimate the output rate.

Temps range from 200-290C for melting. particle size would be nano scale. Some of the materials use fiber but I do not know exactly in what manner or size. All are intended for injection molding and specs associated are based on injection pressures, heat and time. Basically, a mixture of inert conductive dopants with either PBT Thermoplastic resin, Nylon 6/6, PC/ABS, or Polypropylene resin.

The metals are either Nickel, Stainless steel with carbon fiber or Steel Fiber with either PC, ABS, PP, PBT materials and resins.
I do not know about injection moulded pellets having a different viscosity. Other pellets I've seen appear to be used for both. This pellet manufacturer does state both injection and extrusion use but only provides specs on injection.

I would be more worried about the steel fibers wearing out extruder nozzle. But like I posted, this would be an experiment. If I had an extruder, I would run some tests.

I was of the impression that injection moulded pellets had the wrong viscosity to extrude into filament.

I have various conductive plastic material in pellet form used for injection molding I would like to have extruded as 3mm filament to test in my printers. If you have extruder and/or are interested in being part of this project, let me know.
