This process ( http://www.3ders.org//articles/20131209-low-cost-titanium-powders-used-in-3d-printing-for-the-first-time.html
) for producing pure titanium may not relate so much to Bukobots but as a retired Mining Engineer who has worked on designs for a titanium sands mine I am excited. If genuine it seems to be a radical improvement in titanium and other metal oxide systems. Aluminum, iron, and other oxides might also have a paradigm shift. Others out there would know more of the possibility of some kind of 'Laybrick' filament using titanium powder then putting our printed parts in a sintering furnace to burn off the binding compound and fuse the particles. One can dream.
