  1. I have seen more and more articles on printed parts being used in place of other manufacturing processes for production parts. I have seen articles investigating relative strengths of various plastic filament materials. I have seen articles describing the differences of part strength based on build orientation. I can not find a single article (anywhere) comparing relative part strength of a printed part to an injection molded one. How would equivalent strength printed and molded parts differ in geometry based on an FEA analysis? Is FEA analysis even possible for a printed part? If not, how are functional parts to be designed beyond trial and error? How consistent is part strength from build to build, machine to machine, manufacturer to manufacturer? Articles not covering these sorts of topics seems like a significant oversight. Kept to a hobby I get it but the industry is pushing well beyond that.
