i have been trying to do research on the 3d printer on the iss , the refabricator , it was made by tethers unlimited and uses there "positrusion" technique that basically consists of a vice that pushed old plastic parts into a closed die mold that then melts/degasses the parts and then finally extrudes the filament for use in the printer.

this system supposedly extends the lifetime of any plastic due to not shredding the plastic up (shredding plastic reduces its strength over many re-uses) and also is potentially more simple than current machines like the filastruder / filabot.

my basic question : has anyone else done any research on the feasibility of making an open source version ? are the claims made by tui and there refrabicator correct?
