Hi,
I saw this 3D printing technology and think it is the best one out there:
http://en.wikipedia.org/wiki/Electron_beam_melting
http://www.arcam.com/technology/ebm-process.aspx
(some cool videos)
It can print metal (ie titanium, stainless steel) 3D objects from
melting metal powder one thin layer at a time in a vacuum using an
electron beam.
How hard is it to make an electron beam like this? I guess it is
very similar to a CRT electron beam except for the power levels and/or
focus diameter of the beam? Also an electron beam lithography system
has some similarities:

For hobbyist applications this is a good 3D printer for plastics:
