    Default Recycle ABS/PLA rejects

    Are any of you recycling the rejects/off spec. print objects? Is it viable financially to grind up and pelletize the rejected objects, and then make new filament using such a machine as this:

    The Noztek Pro ABS and PLA Filament Extruder for 3D Printers - Noztek Extrusion SystemsNoztek Extrusion Systems

    or

    ReDeTec - Professional and Innovative 3D printing technology

    or are these machines require too much attention and turn out crap filament?

    Virgin ABS is only a dollar or 2 a pound.. An injection molder would probably sell or give you 10 or 20 pounds. You would need a granulator to grind up the bad prints, unless they are really small.

    You will need a spooler to wind the filament. Since the spooler changes the line speed as it winds up and gets larger, you will need a puller to maintain a constant speed. The puller speed will affect the diameter of the filament.
    I would think a single fan will not cool effectively. ABS is not a crystalline resin. With no specific melting point, it will need rapid cooling to stabilize the stream.
