Axis 3D Printer with Radial Non-Planar Slicer – Joshua Bird [video]

This looks amazing!

It also now has the interesting property that one "axis" (the rotary table) can move indefinitely without having to slow down. I wonder if this could be used to massively increase printing speed for part of the object:

- First use the slicer to find the "largest rotational solid" that is contained in your object. E.g. if your object is a cube, the rotational solid would be a cylinder of the same height, if your object is a pyramid, the rotational solid would be a cone, etc.

- Generate a tool path for the rotational solid that is basically a huge, unbroken spiral.

- The printer can print the rotational solid in one go, without ever having to change direction of the turntable (sort of like an "inverse lathe" or a pottery table). This means, the turntable can be kept at high speed, shortening the duration of the whole process.

- After the rotational solid is done, the rest of the object (e.g. the corners of the cube) has to be printed around it in a regular fashion.
