I n addition to its application in media printing, inkiet printing IS
becotning an increasingly attractive option for the distribution and
patterning of materials for a wide variety of applications such as the
fabrication of prototype for the manufacturing sectors. Recently' a rapid
protol)'ping method for building parts layer-by-layer has led to interest in
fabrication of protol)'pes with extra functionalil)' by inkjet printing. ;\ new
system is expected which can produce assemblies composed of parts with
more than one color or with more than one material. This study intends to
utilize Java program to manipulate CAD design data and interface them
\vith a modified commercial 357 -nozzle piezoelectric printer with
experiments focusing on the drop positioning and arrangement required to
fabricate a multi material 3D patterns. Functional fluid materials such as
silver nanoparticle conducti\T ink was successfully printed using inkjet
printing technology to directly write an electronic circuit. In order to study
the parameters affecting drop formation of an inkjet printer, a single nozzle
piezoelectric inkjet system was also dC\'eloped to study basic parameters
such as \'oltage amplitude, firing frequency and fluid viscosity. The
understanding of these parameters reactions gi\'es a broader \·iew on work
in the fabrication of multi material 3D patters using inkjet printing
technology
