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!
A multi axis printer is pretty hopeless without a non-planar slicer, which is why I built this quick radial slicer for the printer. This leverages the printer's rotating nozzle to print simple parts without supports, but there are some limitations to it which I cover in the YouTube video. I'm also working on an optimization based slicer which will be able to print any object without support so stay tuned for that!
There is a wealth of knowledge in the Discussions, Pull Requests and Issues tabs of this repo. The printer is by no means "plug and play", and there are no instructions as of yet, but the information in the discussions should help you get started. Feel free to post questions on the discussions tab.
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.
Some links are included so you know what to get, but they are by no means the best source to get the parts.
