Sheet metal is like most things priced at a premium, so never has it been so important to optimize your material. Here's the cool bit, the image above is a nest of various parts from various customers that was preformed by AI in about 5 seconds. The skeleton from the original sheet weighs very little minimizing the waste to a level that would be near impossible to replicate from manually placing methods. Sharing the material costs and the machine time to the portion of the cut with other customers keeps the costs down.  The software will proportion the time of the cuts to the second for each customer making it all completely fair, even the time to load the sheet is proportioned fairly. For smaller users this saving on the material alone could pay the costs of the laser cost, saving all that labour, remember smarter not harder.
