I found this interesting, they're talking of cars but my first thought was I wonder what this could mean for bike frames?

This, along with 3d printing, could mean we are all able to design and build our own bikes in our living rooms.
Imagine a future BOTM Special, "Here's One I Made Earlier. Today!"

no doubt the cost savings wont be passed down to the customers of the cars built using these techniques (if employed at all).
on a more positive note, if they are able to shape the metal at the same time as bonding it, could this mean the end of the 'triangle' bike geometry???

er, bi-metallic corrosion...? very few practical uses for bonding dissimilar metals at a molecular level!!
Titanium welds as easily as steel (essentially) it's the refining and forming that's more costly.

Re:
Dont get how evaporating aluminium would force two piece together, surely the volume change transforming from solid to gas would do the oposite?
Also wouldnt metaks with different expansion constants warpwhen temoerature changes like bimetallic strip?
