“…3D Stereolithography (SL), belonging to the larger 3D Printing or Additive Manufacturing (AM) family, has delivered a new conceptualization of object design and fabrication with beneficial implications also for Organic Electronics 1 – 3 . When a new technology frontier approaches, researchers are stimulated to push their effort to overcome its limitations.…”

Rapid Prototyping (RP) promises to induce a revolutionary impact on how the objects can be produced and used in industrial manufacturing as well as in everyday life. Over the time a standard technique as the 3D Stereolithography (SL) has become a fundamental technology for RP and Additive Manufacturing (AM), since it enables the fabrication of the 3D objects from a cost-effective photocurable resin. Efforts to obtain devices more complex than just a mere aesthetic simulacre, have been spent with uncertain results. The multidisciplinary nature of such manufacturing technique furtherly hinders the route to the fabrication of complex devices. A good knowledge of the bases of material science and engineering is required to deal with SL technological, characterization and testing aspects. In this framework, our study aims to reveal a new approach to obtain RP of complex devices, namely Organic Electro-Chemical Transistors (OECTs), by SL technique exploiting a resin composite based on the conductive poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) and the photo curable Poly(ethylene glycol) diacrylate (PEGDA). A comprehensive study is presented, starting from the optimization of composite resin and characterization of its electrochemical properties, up to the 3D OECTs printing and testing. Relevant performances in biosensing for dopamine (DA) detection using the 3D OECTs are reported and discussed too.

“…Work has been done on automating parts of handheld spraying to improve the nonexpert production of sprayed images [11,29,45]. Combining 3D printing and spraying has been explored by Falco et al [13] who imagined an FDM and inkjet machine for creating objects with conductive traces. We build on this concept, integrating the conductive trace stage into the 3D printing and using a airbrush spraying process to layer on displays.…”

“…The 3D printed object and the electronics can be designed separately and the only major concern would be the attachment and interconnection of the devices in the 3D housing. Opposed to this approach, Falco et al demonstrated the facile integration of conformal organic electronics devices in 3D printed structures, where the device is directly fabricated on or in the printed object [35]. The 3D printing technique of choice was FDM, because of its low cost, ease of use and high customizability.…”

Conventional electronics requires the use of numerous deposition techniques (e.g. chemical vapor deposition, physical vapor deposition, and photolithography) with demanding conditions like ultra-high vacuum, elevated temperature and clean room facilities. In the last decades, printed electronics (PE) has proved the use of standard printing techniques to develop electronic devices with new features such as, large area fabrication, mechanical flexibility, environmental friendliness and-potentially-cost effectiveness. This kind of devices is especially interesting for the popular concept of the Internet of Things (IoT), in which the number of employed electronic devices increases massively. Because of this trend, the cost and environmental impact are gradually becoming a substantial issue. One of the main technological barriers to overcome for PE to be a real competitor in this context, however, is the integration of these non-conventional techniques between each other and the embedding of these devices in standard electronics. This chapter summarizes the advances made in this direction, focusing on the use of different techniques in one process flow and the integration of printed electronics with conventional systems.
