Electrically conductive filament for 3D-printed circuits and sensors

Conductive and magnetic filaments are revolutionizing three-dimensional printing (3DP) to a new level. This review study presents the current state of the art on the subject, summarizing recent high impact studies about main advances regarding the application of 3DP filaments based on carbon nanostructures such as graphene, carbon fibers, nanotubes, and conductive carbon black embedded in a polymer matrix, by reviewing its main characteristics and showing the main producers and also the products available on the market. The availability of inexpensive, reliable, and electrically conductive material will be indispensable for the fabrication of circuits and sensors before the full potential of 3DP for customized products incorporating electrical elements can be fully explored.

Good Agreement

This article presents the design, construction and measurement of different 3D-printed Sievenpiper metasurfaces. The structures were printed using a conductive filament combined with regular polylactic acid PLA. Measurement shows a good agreement on the electromagnetic behaviour of the stop-bands generated by the fully 3D-printed metasurface and the simulated ideal cases, but with higher transmission losses due to the characteristics of the conductive filament.

Printing Parameters

AbstractIn consequence of the growing diversity of materials in the fused deposition modeling 3D printing technique, electrically conductive materials are commercially available. In this work two filaments based on thermoplastics filled with carbon or metal nanoparticles are analyzed in terms of their electrical conductance. The printing parameters to process the materials with the 3D printer are optimized with the design of experiments (DoE) method. A model to calculate the resistance of such 3D printed structures is presented and a demonstrator as a proof of concept was 3D printed based on these results. In addition, 3D printing of capacitors is investigated.

Microstrip Transmission Lines

The technology of additive manufacturing results in 3D printing of conductive traces in radio frequency circuits. This creates a plethora of possibilities in realizing flexible and wearable electronics. While the prototypes of microstrip transmission lines and antennas have been recently reported, there is now a need of Electromagnetic Compatibility based study of such 3D printed conductive traces. This paper presents a comparative study on the near end and far end unintentional crosstalk components between a pair of microstrip transmission lines made of Copper in the presence of a 3D printed conductive trace made of a commercially available conductive filament, Electrifi. Any physical contact with the 3D printed trace has been purposefully averted to discard the high contact resistance between the trace and such contacts.
