From the project
4 Axis 3D Printer
This is my 4 axis, polar, "core-RΘ" 3D printer – an entirely new type of multi axis 3D printer designed from the ground up.
Check out my youtube video to see it in action! [](https://www.youtube.com/watch?v=VEgwnhLHy3g)
You can view the 3d model online to see how to assemble the printer. Everything is 3D printable, however I got the extruder mount made out of metal by JLCPCB as there is quite a bit of torque on that part. I've also included the gerber files to make your own PCB buildplate, but a sheet of MDF wood would also work.
