[Lab] Plastic for makerbots

[Darcy Whyte]

If plastic comes in granules, then why not make an extruder that accepts
granules?

Perhaps some sort of a bin and a heater. Especially if you had a moving
platform rather than a gantry.

I'm planning on making adhoc stuff rather than production with my extruder
(when it arrives). So I'll probably live with whatever suppliers the
community is using for makerbots and stuff.

But on another project I am planning on manufacturing some propellers. I
haven't figured out how to do that yet but I might need to figure out where
to buy bulk plastic for that.
