3dp_nanodimension_logoWe’ve been hearing a lot of Nano Dimension lately. Just yesterday the Israeli company revealed that they can soon start trading on NASDAQ, greatly growing their presence in the United States market. This is great news for both Nano Dimension and the US market, as the 4-year-old company’s ground-breaking circuit board 3D printing device and proprietary conductive inks have been hot commodities for the electronics industry.

Nano Dimension has so far offered two main types of conductive inks: silver and dielectric. The selection is by no means limiting; these nano inks have a immense variety of applications, and Nano Dimension in addition works with companies to turn it into custom varieties for different types of printing devices and substrates. Now the company has revealed that they are developing a third type of conductive nano ink: nickel. The material is an great one to use for printed electronics, as it has quite solid mechanical properties and high corrosion resistance. It is not without its problems, yet.

The main issue that manufactures nickel ink complex to work with, in inkjet printing at very least, is its tendency to form particle clusters that can clog up printing device head nozzles. Researchers at Tel Aviv University have discovered a way to counter this problem, yet. Professor Gil Markovich, who heads up the university’s School of Chemistry, has generated numerous research studies on nanoparticles. He and his research group have created a novel method of making nickel nanoparticle suspensions that do not clump, that may be perfect for the creation of a nickel ink.

The result: well-defined nickel nanoparticles that do not cluster together. Nano Dimension’s fully-owned subsidiary, Nano Dimension Technologies, has signed an agreement with Ramot, Tel Aviv University’s innovation transfer company, to collaborate on an application innovation for the new material, i.e. a printable ink.CRs-BRFWoAAd0HD.jpg_large

“This collaboration with Tel Aviv University, in combination with Nano Dimension’s intellectual property and know-how, may assist advance development of new ink formulations tailored to Nano Dimension’s printing technologies and a wide range of new 3D printing applications,” states Nano Dimension. “Potential applications of nickel nanoparticles include sensors with a high spatial resolution, via high end print heads and a precision micrometer scale. Using this new innovation with Nano Dimension’s 3D printing system can manufacture it possible to embed sensors inside the layers of a PCB, a system not possible with conventional making, opening up a world of possibilities for the monitoring of different types of energies and their derivatives, such as capacitance, magnetism, temperature and radiation.”

Nickel in addition acts as a barrier against oxidation, that may greatly assist in the production of printable circuit boards (PCBs). Protection of oxidation is significant, particularly in the production of elements created with nano-metric corrosive metals, that oxidize automatically as soon as they are exposed to air. This is amazing news for the electronics industry, and additional cements Nano Dimension’s position as a leader in 3D printed electronics.
