Specifics of 3D-Printed Electronics
3D printing of electronics is very prospective technology, so it has strong demand for the research and application. Nowadays 3D printing can be applied from rapid prototyping using simple and inexpensive table-top commercially available 3D printers to the low-cost 3D fabrication of functional electronic circuits combining printed and mounted components. Implementation of the 3D printing technologies to electronics depends on a material printability, its electric properties and mechanical stability. Extensive research devoted to the development of the printable materials with new functionality, e.g. nanocomposites. Nanocomposites based on polymer binders filled with structured carbon nano-objects showed, for example, good prospects as electromagnetic screens in microwave and infrared spectral regions. 3D printing technology can produce from these materials complicated supports and housings of various shapes providing charge transfer and electromagnetic shielding. Development of 3D structures made of conductive polymers requires exact modeling of their electric and electromagnetic properties. In this article we describe 3D printing technology with thermoplastics including carbon nanocomposites and share an example of 3D conductive lattice modeling.
This research was partially funded by H2020 RISE project 734164 Graphene 3D. We are thankful to Alesia Paddubskaya and Polina Kuzhir, Institute for Nuclear Problems of Belarusian State University, for valuable discussions.
