I’m brushing up on the current state of bowden extruders. I got fed up trying to get one to work three years ago (when they were a brand new concept) and haven’t played with one since, but like everything else, they seem to have come a long way since then.
Ultimaker, Reprappro, Seemecnc and Makibox are making machines that use them. Am I missing any? I’m particularly interested in knowing about any that are being sold separate from a printer. Reprappro’s and Seemecnc’s are, Ultimaker’s doesn’t seem to be (though you can probably get most of it as replacement parts). @Jonathan_Buford , are your extruder parts going to be available separately?
