Share here all your information, suggestions inspiration for a extrusion machine. The more information we gather the better the machine will get.
I have seen a extruder that is being made called Recyclebot. Here is the link to the wiki: http://www.appropedia.org/Waste_plastic_extruder
A 3-man startup in Canada named ReDeTec have started an indiegogo campaign for a desktop 3D-printing filament extruder that they claim has much better performance than the Filabot and a bunch of other similar products, with some new innovation in their extrusion system that they have not described, saying that they have a patent pending for it (I have not found it so far in the Ca or US PTO). I don’t like the secrecy, though I understand why they are doing it, but this is one to watch for sure.
Definitely interesting stuff in there
Here is a nice video documentation about the construction of a 3D-Printer Filament Extruder, maybe there are some interesting thoughts and experiences about extruding plastics:
Cool project, nice documentation. –thanks for sharing!
