This dissertation presented below was written as part of the MSc in Strategic Product
Design at the International Hellenic University.
3D printing is an innovative and unique additive manufacturing technology that without
a doubt offers a high degree of freedom for the creation of various products that
incorporate electrical parts, such as sensors, switches and connectors. The ease of access
in low-cost, dependable, conductive material will be undoubtedly vital in the fabrication
of these products. Up to this point, there are not many reliable 3D printable conductive
filament composites with high enough conductive properties that can be used in the
fabricate of circuits for fused deposition modeling.
In view of this, we present the fabrication, testing, characterization and application of an
inexpensive thermoplastic conductive material that has been prepared into filament
form for 3D printing. Results from the dynamic ultra-micro-hardness tests, as well as
SEM analysis are thoroughly presented in order to fully define the structure along with
the mechanical properties of the developed composite.
An emergency stop button (e-stop) was designed and printed with the newly created
prototype and applied to a small circuit design in order to demonstrate the potential use
of this composite into circuit applications.
