Which ABS pellets?

[printrboy]

Which abs pellets are used by extruders for making filament for 3d printers?
I got few kg from a factory which uses ABS for injection molding.
Can that be used?
Or is ABS used in 3d printers different (like something else added or slightly different molecule)?

There are a couple different grades used in 3dprinting. Im not on a computer so going off memory...one is pa-747 and something 94. Someone can chime in here and give correct info
