According to the www.liquidmetal.com site, all convetional materials are
probably made obsolete by the technology.
So, any day now, someone will use the liquidmetal to do anything that
can be done in any other material.
But, maybe it isn't entirely that easy........... Now how could that
Casting as a rule hasn't eliminated all other forms of shape creation of
Maybe, there is a clue to the future of liquidmetal in that observation.
Something which is "great" is not "great" for all things.
For example, I can imagine placing these etched features on low cost
aluminum alloys for adhesive bonding purposes in complex assemblies.
I CAN CAST IT, BUT I CAN'T GET IT OUT OF THE MOLD.
Molds for solid parts often have smooth surfaces or else are easily
broken and disintegrated to remove the molded part.
It doesn't readily follow that a cast liquidmetal including these
roughened surfaces will easily be removed from the mold that was used in
the casting, let alone other cost considerations.
Well, suppose the surface of the mold could coated with a surface
layer that could be easily broken or dissolved? That might enable the
cast metal to be more easily freed. Then the coating could be
reapplied or re-formed, for the next casting.
I once worked for a company that developed a method of molding engine
manifolds out of plastic for a major truck manufacturer. It was
considered advantageous to injection-mold the part as opposed to
machining such a convoluted shape.
The core of the mold was tin which had a lower melt-point than the
plastic, so that it could be melted out of the inside of the molded
plastic manifold piece.
