RepRapable Recyclebot: Open source 3-D printable extruder for converting plastic to 3

[MOST]

Thank you! We certainly know of PP but are not directly working with them -- they have real strength in machine shop work - which we only sometimes do (depending on students and shop availability - as it often is booked solid mid semester) so we have been trying to push really hard on more accessible replication techniques. This ones still has a long way to go - I am sure we can push the costs further down - currently we are working on a webcam based filament diameter sensor feedback loop that will help simplify it again....
