The Mixer worked pretty well with HPDE and PET when it was run for about 30 minutes but its really not feasibleA kitchen wizz would probably work better because it would cut rather than munch, but they are expensive for what we might get/use out of it. looked in second hand stores and trademe
Heres a quick model of the kind of chopper that would work best for all type of materials and states. Also would look cool when you put a makerbot model into it and chop it. Its Based off the chopper Jono posted awhile back.
Depending how finely it chops it may need a second stage to chop it finer. But just speculation at the moment
We can possibly make a larger extruder to fit larger pieces in using a 10-15mm screw, but the amount of material that it would push through may be unfeasible, but something to fall back on
It has 50 pieces which are 3mm thick. There is a plasma cutter in the workshop that would easily cut them out. Using a mdf template cut on the laser cutter and allowing for the cutting tolerances it would be pretty easy to make. and since its kinda dangerous hand operated would be better.
Or it may be a good opportunity to talk to industry and see it we can get someone to supply and or cut the material for us.
Have also looked into meat grinders but the way the material is cuts/grinds may be ineffective for our needs and has same issues as we do with extruder.
Total dimentions above is W 70 x L 80 x H80 but thats very Flexible
