Hi John
I'm not from an engineering background like your self so I think like many this 3D ability in metals was a surprise. Your right a company like GE with there resources should be able to archive more and I'm sure they will but it was there first two runs!. I sincerely hope using technology like this allows prototyping costs to come down sooner than later allowing development of clever and innovative designs, not just from big company's but from guys with good ideas in sheds and workshops up and down the country. Imagine having one at your disposal and how quickly your ideas could be developed. One thing for sure if we don't re-adopt a "can do attitude" the same as I have experienced in other parts of the world we will drop even further down the industrial ladder.
