[HH] 3D printing

[Kurt Keville]

I'm a partner with one over at the FabCollab... I think our 
experience has been that there is virtually no market for this 
outside people who want fairly fragile mockups. The high end printers 
from companies like Objet might make structural pieces but those 
printers are $50K or so. That's a pretty large chasm to cross, with 
no help from Moore's Law...
