Re: The RepRap*R* - 16 years ago
Okay, coming into this late, but this topic tickled some ideas in my brain... As for grinding, what about a very slow cut. I'm thinking a mechanism like a paper shredder. Successive ones, of progressively smaller cut. It likely won't get us down to a dust, but I think it'll get down to small enough to feed into an extruder. As for the extruder, what about something like they use in candy maby abrannan - Plastic Extruder Working Group

The idea I had was to create a "indentured servitude" model. If I had a working RepRap/RepStrap (I don't) I would do something like this: You send me $X dollars for a set of RepRap parts (Where X = SUfficiently large amount of money to weed out those who aren't committed to actually making a RepRap in the short term)I print and send you a set of RepRap parts. You make your RepRap and print twoby abrannan - General
