Rapid Manufacturing of Aluminum Components
T. B. Sercombe and
G. B. Schaffer
A manufacturing technique for the production of aluminum components
is described. A resin-bonded part is formed by a rapid prototyping
technique and then debound and infiltrated by a second aluminum
alloy under a nitrogen atmosphere. During thermal processing,
the aluminum reacts with the nitrogen and is partially transformed
into a rigid aluminum nitride skeleton, which provides the structural
rigidity during infiltration. The simplicity and rapidity of
this process in comparison to conventional production routes,
combined with the ability to fabricate complicated parts of
almost any geometry and with high dimensional precision, provide
an additional means to manufacture aluminum components.
