Hi, im Sergio Salazar, im from Mexico, and im a part of a group interested in the recycling plastic for social activities, in the other hand we are very interested in to produce filaments from recycling materials, we have been investigate about this process, but we can't find how the 3D printers can identify this material and can work with it, so, is it necessary a special 3D printer that can work to this material? or it need a special additives or something like that? or maybe is it the extrusion procces the key?.
I would really appreciate if you help me with my research, thank you.
