I haven't seen this machine operate, but it seems you would need to have a lot of very small parts to make before it would be justified.
The drawbacks would be it is very noisy, has a very small working envelope and its 3D CNC capabilities are not fully developed.
For me, if I was 3D printing, I would use a different printer. If I was laser engraving, I would like a larger working space for front panel engraving etc. If I was using CNC I would want a larger working envelope and I would want to be sure it could accurately drill a pattern of holes, including small PCB vias.
An interesting machine none-the-less. (They do make a larger one as well of course)
