- There seem to be two major issues that are unaddressed in the statement of
- your problem:
-
- - Processing 1000 sheets in a work day means only 28.8 seconds per sheet.
- Many processes will take an amount of time proportional to the length of the
- boundary of the final shape.
-
- - Most "intricate" patterns involve a large number of pieces which would fall
- apart from each other. Other "intricate" patterns, although in one piece
- will be so fragile and/or flexible that maintaining their shape after removing
- them from the manufacturing apparatus will be nearly impossible.
-
- Also, it appears that you wish to use these paper-thin objects to assemble a
- three-dimensional solid (i.e. CAM via the slice method). If this is in fact
- the case, you should state it. The additional information might help lead to
- a solution.
