  2. ABS is the other common one for cheap desktop 3D Printers. It's stronger
    but harder to print (shrinks more as it cools, causing prints to peel
    up from the print bed at the edges). It also needs more heat to extrude,
    is not biodegradable, and it stinks more when extruded.

    ABS is what they make the cheap "Project Boxes" at Jaycar from, among
    other things. You'd use ABS over PLA for printing guns, with solid infill
    too (unlike a safety report I saw, must have been biased).

    HDPE is good if you make your own filament because it's what they use for
    plastic bottles and the like, so you can make filament out of waste.
    Problem is that it's even harder to print with.

  3. Personally I've got various bits of cut off metal and a length of an old
    grain auger in the shed from an unfinished attempt at a DIY commercial scale
    plastic extruder from a few years ago. I'd love to get back to that, but I'd
    probably need to devote a few weeks to really get it built (and perhaps a lot
    longer to get it working...).

    On the sensible scale, there have been a few small extruders spring up on
    the 'net in the last year or so. Here's a good starting point:

    There might be kits for sale online as well.
