If trade secrets are important, they need to be kept secret. Personally, I think that open source hardware will pave the way to space. Unless you are in the business of building hardware (SpaceX makes rockets) you want the designs to be out in the open to drive costs down. Having said that, open sou...

This is really neat. I wonder how much a DMLS machine costs. [quote=""joertexas""]I'd be concerned about the part's strength. It's one thing to make something in a particular shape from a certain material - it's quite another thing to preserve the strength of the material.[/quote] I think you genera...
