Topic: which ABS pellets are good for making filament?

I know there are companies that sell pellets targeted at "home" 3d printer filament extruders.

But my question is what kind of "pure" (no colorant, agents) ABS pellets work best for making filament for 3d printing in general? Or does the A, B and S ratio not make much difference to care?
I would assume since people are recycling plastic from their old electronics covers and even refrigerators into filament there should be some data by now on whether some ABS types are no good for 3d printing or which are better.

This is covered in the polymer extrusion sticky:

You want to look at melt flow rate to improve extrusion speed. Sabic MG94 is what Stratasys uses in their filament, PA747 is also popular, plenty of topics on those two and others here.

E3Dv6 All Metal Hotend - the premier 3D printing hotend

Re: which ABS pellets are good for making filament?

Thanks for the links man.
I guess I should ask for data sheets and just look up the MFI value?
MG94 and PA747 are ABS pellets produced by certain companies, not ABS "types" (standards), right? I should have found out bu googling, but I can't.
