How is the case manufacturing industry organized for various devices?

Question

Frame

Friends, I would like to delve into the topic of the production of various cases for devices. If you look at any device, device, gadget made outside the Russian Federation - a high-quality case can be plastic, aluminum; good paint materials. Why are we all wrong? and if so, then this is a rarity and special secrets. Why every second startup is trying to print cases on a 3D printer, when all over the world they immediately produce a good prototype regarding the case.
It is very interesting to learn how small startups solve the issue of cases, I throw in a few questions:
1. How is the prototype of the case coordinated, what are the nuances in drawing the industrial design of the prototype, its cutting and return to production;
2. Why the cost of manufacturing cases in Russia is N times more expensive even with delivery than China;
3. What is fashionable to do 3D models of cases now, what is the situation in Russia with industrial design (just if you go to behance, dribbble there every 3rd project from the industrial design category);
