I like this quote:

“Traditionally, hardware capabilities have driven materials science developments. But we are going through a change now where material developments will start to lead hardware developments … In the intermediate to long term, it should not be surprising to see AM companies getting into materials science in a pervasive symbiotic relationship—the marriage of technical science with materials science.”

I wonder if Vivek Dave knows anything about materials science with his background:

Education:
Massachusetts Institute of Technology
Ph.D. Materials Engineering, Minor in Mathematics
MS Materials Engineering
California Institute of Technology
BS with Honor, Engineering and Applied Science

I also like this quote also:

"Quality consistency issues, especially in producing fully dense metal parts, result from excess heat that leads to stress and voids, particularly on layer boundaries. Repeatability can be improved by embedding controls within the machines so that in-situ dimensional accuracy is ensured, as well as by subsequently conducting automated inspections. According to one expert we interviewed: “Currently, the strength in the plane of layers is not uniform. Those are issues to be dealt with. In principle, you can deal with those quite well because you have access to each layer and the entire geometry. You can see every layer being laid down. I see these [issues] as temporary hiccups to getting good-quality parts, because you can, in principle, do a 100 percent computerized inspection in a completely automated process.”

And GE purchasing 100 EOS printers is awesome news. We know GE has at least 35 of them now, right?
