The application of silicones and thermoplastic polyurethanes (TPUs) in the number of electronic and flexible device applications has multiplied through the years with its excellent composition control and the ability to prepare various forms primarily through the injection molded and thermo-formed processing shapes. This means that their thermo-mechanical properties can be tuned towards more mechanically compatible properties to the human body including elastomeric properties. However, in a number of prosthesis devices including artificial body parts, sensors, implants, etc. 3D printing is emerging to be an alternative for additive manufacturing with its rapid-prototyping advantage and the ability to incorporated new polymer and nanocomposite in processing methods such as fused deposition modeling (FDM), stereolithographic apparatus (SLA) and viscous solution printing (VSP). It should be a viable method for the limited and specific production of flexible electronic devices that are fit even for personalized healthcare This talk will highlight our work on 3D Printed Silicones, 3D printed TPU, etc. and 3D Printed nylons, to form basic material compositions flexible <span style="background-color:rgb(246, 213, 217)">electronic nanocomposite materials containing graphene, carbon nanotubes, carbon black,e etc. </span> Structure-property relationships correlated with the formation of improved modulus and flexural strength with increasing amounts of electronic nanofiller components.
