To “build” industrial tools, you typically need to design and manufacture them to a specific need, rather than physically constructing them from scratch by hand. This involves a process of understanding a problem, creating detailed CAD designs and tech packs, developing prototypes, and then using advanced manufacturing processes like CNC machining or assembly lines to produce the final tool. The focus is on customization, ensuring manufacturability, and integrating the tool into a larger process to increase productivity and efficiency.
