You met with Charles? I also met him last year in June, pretty cool guy! And I like what he is doing with his extruder. I have one, haven't had the opportunity to try it but using silicones I can imagine one could make some pretty handy things.
The feeding process took quite some time to get started, but you know.. good things come to those who wait
Yes that is the guy, top guy!!
And haha yeah the purge can take a while. He said it had a few tweaks that needed making, and it is at a rather experimental stage, but he'd had some good prints from it. I'll get some pictures up.
