I'm pretty sure this is addressed in both the video and the website. There's a whole section where it shows swapping out various tools at different angles for different functionality, including 3d printing and CNC milling.

But if you looked at their CNC example, the result was pretty dang coarse. Painting on something like XTC-3D from Smooth-On is one way to get a better finish while avoiding tedious sanding.

Hi, I am the developer of the Machine. It is a bad machining. But not because the machine. I don't have a good 4 axis paid cam software. So, I developed a software myself to generate 4 axis milling. Obviously it has a bug and it wasn't possible to generate a finish work.

After I release mechanical design v1, I will work on the codes and hopefully will be able to demonstrate a clean finish work.
