To develop a 3D printed material system for extracting the electrical conductivity of the piezoelectric material, to fabricate the integrated piezoelectric prototype and it’s always have a good availability with the more number of variety of materials for making with special characteristics. This paper introduces with direct ink writing method for printing the piezoelectric material by using multi materials such as terphinal, ethyl cellulose, methanol and graphene. The materials and processing steps for the manufacturing the 3d printed piezoelectric component, the individual material characteristics and the equivalent circuit is provided. Electrical Conductivity analysis on the 3D printed piezoelectric done with the above mentioned material and the result has been discussed by using the four point probe method.

“…The physical properties of PLA can also be tuned by incorporating nanoparticles using different synthetic strategies of polymer/inorganic hybrid nanoparticles. − Nanoparticles can also add new functionalities to the polymer matrix, for instance, biocidal characteristics. − These materials establish an alternative for medical applications or food packaging. Nanoparticles with antimicrobial activity, such as silver, copper, or photoactive oxides such as TiO 2 , are usually considered feasible alternatives to improve mechanical strength, prevent growth, and reduce the adhesion of microorganisms in the PLA. , Nevertheless, the toxicity of silver nanoparticles is still under evaluation, and titanium dioxide (TiO 2 ) needs to be activated by UV irradiation …”

Antimicrobial films based on poly(lactic acid) (PLA)/Dlimonene/calcium oxide (CaO)-based nanocomposites were prepared by extrusion and successive thermocompression. D-Limonene was incorporated into PLA at a concentration of 5 or 10 wt %. Venus antiqua clamshell-derived calcium oxide (CaO) nanoparticles with an average diameter of 11.2 ± 9.9 nm were added at concentrations of 3 and 5 wt %. A decrease in the glass transition temperature (T g ) by ca. 20% corroborated the plasticizing effect of D-limonene compared to pure PLA. The incorporation of 5 wt % CaO in PLA composites promoted a ca. 15% decrease in T cc . Although CaO induced a lower Young's modulus and a lower thermal stability in nanocomposites, excellent antimicrobial performance was demonstrated. Both PLA/limonene and PLA/ limonene/CaO films reached 99.99% efficiency against Escherichia coli, regardless of the source of irradiation, D-limonene, and nanoparticle loading. Therefore, these nanocomposites establish significant progress in developing sustainable antimicrobial materials in the fields of medicine or food packaging.
