Anyone playing in the CNC field, (personal or professional) knows the 3D 
printer world relatively well these days.
Even me..., just finished adding steppers to my own mill/lathe for full 
CNC....now just completed building a dedicated touch screen controller with 
custom keypad to drive it all (electronics design engineer by profession)

The 3D printers best suited to such a project (bell housing) are now being 
purchased by small companies to replace foundry work.
They deposit cintered metal where needed in the layer, and sand around where 
not. Then a high powered laser fuses the layer. The system repeats until the 
whole unit is built up. Cl;ear away the sand and you have a part in hand.

Right now the biggest industry concern,,, yes... people can print a hand 
gun! It's been done, and fired. Some guy on youtube even fires an AR-15 
where he made the main carrier on a 3D printer. Anything made from plastics, 
nylon, poly, etc can be made on a 3D printer. Now, even metals of all types.

metal examples  http://www.youtube.com/watch?v=88BPmL8cGAo
kind of plasma cutting in reverse...metal deposition 
Zcorp ..wild all in one pieces 

oh..car related...Even Jay Leno has his own 3D printer. He uses it to proto 
parts ...makes blanks for sand cast molds to make parts he needs not avail 
anywhere else.

nfi...just dreaming what can be done....sooner than you think.  :-)
