Look up "stereolithography" on the internet, and see it that technique is suitable for prototyping what you have in mind.
Unless you got something so revolutionary and life-altering, having just a prototype isn't going to get the ball rolling. No investor will give you any money without having some concrete sales figures in your pocket first. Of course you could fund the entire project yourself, skip the investor all together and make a deal with a manufacturer to mass produce and bring it to retail.It will cost you a pretty penny and you best know exactly what you're doing.
Don't really know what exactly your ideas in your head are but the above is a basic guideline to get any prototype funded, manufactured and introduced to the masses. Best of luck;Lode.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
