Has anyone tried fitting a conveyor belt to the wedge's Y-axis instead of the moving table? Looks to me from the videos that it wouldn't be too difficult, and would allow it to drop printed parts into a bucket for very long runs, and/or print very long parts if the conveyor was extended out the front.

Are there any flexible materials that the extruded plastic will stick to enough for a solid print, but not so much that it causes problems when the belt goes around a roller?

Discuss!

The problem with this I see is that, insuring that everything sticks to the bed, insuring that he whole bed is even, and doing so may mean difficulty in removing it.

You can try, be interesting to see if it works
