I got an idea to use many needles for a multi-point extruder for plastic 3D printing.  Still I don't have much time to work on any project at the moment with work and some personal issue and also little extra money for projects.  But enough complaining!!  

Thank you to all my new project followers it will be done and awesome once I can work things out and then you can build one yourself.  I am considering setting up a single row print-head to demonstrate the process of arc printing.  It will be more mechanicly complicated than the original arc printer design but it saves me time making 100 rows of 100 wires at least for now.
