Scenario 1: I would use working manual, in machines, so I can control all the details of the desing, I would hire technical, and they would do the job with the specification

Scenario 2: I would use foundry because I can controlling the process to produce many parts, with saf, and in the correct times

Scenario 3: I would use "remoción de material" (in spanish, I don´t know how to say it in english) it consist to work the material base directly with the machines and I would have all the machines automated, so all the product would have hight performance
