I really dont know about this, part of the reason CNC mills today both hobby and industrial use gantry designed tables is because of the force needed to press into the work piece. Its not excessive by any stretch of the imagination but its still a factor in cutting speed.
Cutting lamination - Carbon fiber, Fiber glass, composite hardwood and so on shouldn’t pose much if any issue. Until you start chattering, and the vibrations start moving the CNC off alignment. As well traction issues, dense, harder materials will require more force toward the cut line - which again falls against the weight and the traction that the design will allow.
This might do well for super thin stuff like what is shown, but i wouldn’t hold my breath on it being any better than a Shapeoko, X-Carve or Black foot/Blue Chick CNC routing table.
