Abstract
Microcasting is one of the key technologies enable the manufacture of small structures in the
micrometer range or of larger parts carrying microstructures by using a metal melt which is cast into a
microstructured mold.
Microcasting, is generally identified with the investment casting process, which
is known as the lost-wax, lost-mold technique.
A main step in micro investment casting is making
disposable patterns which have sufficient mechanical strength and dimensional accuracy.
In this study
a review on available microfabrication methods to produce such patterns has been dow
