does 3d printing pose a threat to qhl et al., page-5

I hear ya dog. I'd heard of this technology a couple of years ago and it was being used for mostly that- building 'prototypes' of stuff before actually tooling up to make things the 'old fashioned way'. However if you read this article you'll see the technology has advanced way past that now. It truly is going to be a revolution. It's still early days. It may not affect QHL's short/medium term prospects but it just made me wonder about the future for manufacturing in general. The article's mention of aerospace is pertinent though.
