Interesting - I’d like to see more about the “ejection mechanism” as the video shows the print getting tilted up which I guess is breaking the seal from the print surface (I thought the print surface was held down magnetically) before I can really comment.
Being able to repeatedly 3D print without requiring human intervention is definitely a need (which I’ve had) but I suspect that this approach is very model specific (ie big base, no small pieces that can get damaged).
