A benchmark between the commonly used production methods for thin sheet metal parts shows an obvious economic advantage to Photo Chemical Machining within a wide range of production volumes.
Programming + setup: typically 200 - 500 EUR
Unit price depending on the cutting time.
Initial costs (construction & tooling): typically 10 000 - 50 000 EUR
Unit price is low.
Photo Chemical Machining:
Initial costs (CAD work & photo tool): typically 300 - 700 EUR
Unit price depending on number of parts per sheet and thickness.
Economical benchmarking (graphic presentation):
The graphic presentation gives the answer. The profitable quantity lies between "X1" and "X2".
Naturally it is depending on the actual size and complexity of the part but ...
For bigger parts - typically: X1 = 100 and X2 = 10 000 units
For smaller parts - typically: X1 = 1 000 and X2 = 100 000 units
For very complex parts* - e.g.: X1 = 10 and X2 = 1 000 000 units
