This is your last chance to sign up for the Light Green Machine Institute Conference, and by last chance, we need you to sign up as soon as you see this!

So far, we have registrants to the conference from the following mill companies:

Domtar, Georgia-Pacific, Greenpac, MeadWestvaco, Pratt, RockTenn, Smurfit Kappa, Wausau

Now to the inspiration for the week:

With my wife, Laura, now working in the aerospace industry for the last five years, our "pillow talk" is often cross-pollination of technologies from both industries--sort of a paper airplane experience if you will.  Recently, Laura has been heavily involved in additive manufacturing, that is, the concept of "printing" 3-D parts.

This came to me the other day after one of these discussions.  Why can't we "print" concrete foundations, walls and other such structures we need?  Why can't industry build us a "3-D" printer that moves through a construction site and prints concrete?  The "gunite" process has essentially been the early generation of this for years.

3-D printed concrete eliminates forms.  This is a huge savings.  We could also print small structures, such a pump foundations, with voids in them to reduce weight.  

Any thoughts?
