Pellet Extruder - Prototype
Description
THIS IS A PROTOTYPE/CONCEPT. I HAVE NOT PRINTED THIS. I DO NOT VALIDATE THAT THIS WORKS, YET :). I made this design to promote a new concept of "open source" pellet extruder. I designed this with easy commercial items to reduce costs. If you know about other material that would better the design, please share :).

It uses commercially available 12V 40W-50W heaters. If you use 24V, you can probably put 2 in parallel. otherwise, a mofset for the extruders or another power supply may be required. A spinner ball bearing is used as well. I´m not very sure if these nozzles can withstand the pressure from the plastic coming out. I was planning to metal print some nozzles as well. http://bit.ly/2PHd7oC THINGS TO CONSIDER: All plastic parts should join metal parts with epoxy glue to maximize stiffness. Many people told me that the design would need more cooling or fewer heaters. If you would like to collaborate personally with this design, feel free to contact me: elingsanto@gmail.com Long live the open source community!
