The increasing demand for flexible, stretchable and embedded electronic technologies has resulted in the deployment of Additive Manufacturing (AM) techniques for the production of electronic components and interconnecting conducting tracks via the accurate and selective deposition of conductive inks. The electromechanical performance of the conductive track material is captured by the response of the effective resistivity under increasing mechanical strains and of particular importance for the functionality of the printed products.Continue reading “The Electro-mechanical analysis of conductive tracks in Lightweight Embedded Electronics”

The field of additive manufacturing, which in the last years has gained a lot of interest both from the commercial and the academic world, needs now a boost from the materials side. If materials with special properties as biocompatibility, high mechanical resistance or temperature resistance are already present on the market, materials with special functionalities are still waiting for first release. Especially as regards materials with electrically conductive properties, which would represent a breakthrough for 3D printed electronics. In this perspective, our research group at the department of Applied Science and Technology at Politecnico di Torino is studying novel materials to allow the additive manufacturing of electrical and electronic components. Among different tests, the photocurable resin based on PEDOT:PSS seems to be the most promising one. Some application examples will be also reported.Continue reading “Electrically conductive polymers for additive manufacturing: current research at PoliTo”

Roughness of as-printed 3D parts is limiting the real breakthrough of Additive Manufacturing. Post processing technologies consist out of subtractive techniques such as grinding or sanding, or out of additive techniques such as coating.
In this presentation Ultrasonic Spray Coating as an additive post processing technologie is described to first of all reduce the roughness of Selective Laser Sintered substrates down to less than 2 micrometer and further, functional formulations consisting out of a polymer and nanoparticles is prepared to not only reduce the roughness but also add functionalities to the surface of the 3D substrate such as scratch resistance or superhydrophobicity.Continue reading “Roughness reduction and functional coating deposition on additive manufactured substrates with ultrasonic spray coating”
Researchers in Oregon State University’s College of Engineering have taken a key step toward the rapid manufacture of flexible computer screens and other stretchable electronic devices, including soft robots.
The advance by a team within the college’s Collaborative Robotics and Intelligent Systems Institute paves the way toward the 3D printing of tall, complicated structures with a highly conductive gallium alloy.
Researchers put nickel nanoparticles into the liquid metal, galinstan, to thicken it into a paste with a consistency suitable for additive manufacturing.
“The runny alloy was impossible to layer into tall structures,” said Yiğit Mengüç, assistant professor of mechanical engineering and co-corresponding author on the study. “With the paste-like texture, it can be layered while maintaining its capacity to flow, and to stretch inside of rubber tubes. We demonstrated the potential of our discovery by 3D printing a very stretchy two-layered circuit whose layers weave in and out of each other without touching.”
Findings were recently published in Advanced Materials Technologies. Continue reading “Highly conductive 3D printable gallium alloy shows promise for flexible electronics”
Recently I caught up with Simon Fried, chief business officer and one of the founders of Nano Dimension, an Israeli start up that is targeting the market for printed circuit boards or PCBs.
The end goal for many people in additive manufacturing is not so much the ability to print individual components but rather to print a sub assembly or a whole object in a single process. Ultimately this also means being able to print the electronic elements of those objects, which explains why there is so much interest in Nano Dimensions. Continue reading “Silver or copper?

The optics industry is an old analogue industry. For a few thousand years people have been making optics in the same way, using polishing and grinding processes. This is time-consuming, expensive and difficult to scale up. In the 1950’s, injection moulding arrived and standard lenses could be made in high volumes. Now, Luxexcel’s new additive manufacturing techniques are allowing new possibilities in optics and photonics. Continue reading “Optics Industry: Digitizing Old Analogue Manufacturing Techniques”
