Dry ink-less digital printing with in-situ sintering

Current printing technologies are based on wet printing methods such as inkjet and aerosol jet printers that suffer from complex and expensive ink formulation, limited printing material options, contaminations, low shelf life, and costly post-processing. Slide one shows a typical process.

At TechBlick's free-to-attend online event on Printed Electronics Innovations on 2-Dec-2022 (, NanoPrintek present the world’s first “dry multimaterial printer”. This novel technology can transofrm printing from a traditional liquid-based to dry printing technology. This printer is schematically demonstrated in slide 2, showing how nanaoparticles are in-situ generated from a solid target to form a jet of nanoparticles which digitally prints onto the end substrates without ever requiring an ink.

Slide 3 shows examples of devices printed using this technique on flexible substrates including paper. In this examples, copper and silver as well as materials such as Al2O3, BTO, SnO2, and TiO2 are dry printed!

The Key technology advantages include

1) on-demand and in-situ generation of various pure nanoparticles without contaminations,

2) in-situ and real-time laser sintering of nanoparticles on various substrates with no further post-processing,

3) multimaterial printing of hybrid and composite materials and structures.

The liquid-free nature of the system, the tunable flow dynamic of the nanoparticles, and the real-time sintering mechanism make it uniquely suitable for operating both on the earth and in space. Moreover, this technology is capable of printing sensitive materials such as copper on biodegradable and water-soluble substrates such as paper.

To learn more about the latest, join us for free on 2 Dec 2022 to hear Prof. Mahjouri-Samani, the innovator and CEO of NanoPrintek, present the latest on this technology.
