Jet Engine made on a 3D Printer: http://youtu.be/6rX4xv5-NvE
this is good ,sir how can one used it
I don’t think this one is meant to be useful. It’s meant to show how the turbine engine works. I liked how it shows a twin spool or twin shaft design. To be useful, it probably needs a lot of changes, and probably to be made from metal.
