A collection of 33 droplets was constructed to form the word “OMU” utilizing a cutting-edge optical vortex laser-induced printing method. This innovative approach allowed for the accurate placement of droplets without the formation of any extraneous satellite droplets. The research was credited to Ken-ichi Yuyama of Osaka Metropolitan University.

Revolutionary Advancements in Microprinting Offer Economical and Time-Efficient Solutions
While the possibility of printed images rivaling the clarity of a mirror remains elusive, scientists at Osaka Metropolitan University have made considerable advancements in the realm of high-precision printing. They have employed a groundbreaking technique based on optical vortex lasers, which permits the exact positioning of diminutive droplets at a micrometer level of precision.
The Existing Limitations of Inkjet Technology
Inkjet printing is a widely recognized method that dispenses small droplets of ink directly from a nozzle onto a substrate. Nonetheless, the technology encounters challenges when dealing with ink formulations that are both viscous and dense, as these characteristics frequently result in nozzle blockages. This issue has catalyzed the pursuit of more sophisticated printing technologies.
Pioneering Work by Dr. Ken-ichi Yuyama and His Team
Under the leadership of Dr. Ken-ichi Yuyama, a lecturer at the Graduate School of Science at Osaka Metropolitan University, a research group has successfully printed droplets with a uniform size of approximately 100 µm. This was made possible through the use of a fluorescent ink film that is roughly 100 times more viscous than water. By irradiating the film with an optical vortex, the team achieved printing results characterized by extraordinary positional accuracy on the micrometer scale.
Dr. Yuyama elaborated, “By employing a unique type of laser beam, known as an optical vortex, we have managed to consistently print using high-viscosity liquids. This method enables us to construct microdroplet laser arrays and execute the micropatterning of conductive nanoinks and bioinks for cellular scaffolds. This lays the foundation for the development of next-generation photonic and electronic printed devices.”
The findings of this research were recently disseminated in the journal ACS Photonics, under the title “Fabrication of an Array of Hemispherical Microlasers Using Optical Vortex Laser-Induced Forward Transfer,” authored by Ken-ichi Yuyama, Haruki Kawaguchi, Rong Wei, and Takashige Omatsu, dated 13 September 2023. The DOI is 10.1021/acsphotonics.3c01005.
Funding for this project was provided by the Japan Society for the Promotion of Science and the Japan Science and Technology Agency.

If they can pattern conductive nanoinks, then whats stopping them from revolutionizing the chip-making industry? This is huge, ppl.
i gotta say, Dr. Yuyama and his team are on to something big here. Precision at a micrometer level? thats the future guys.
Never thought I’d see the day when inkjet tech would be considered outdated. I wonder how fast this new method will take over the market?
What about the environmental impact? Does this new method require special inks or materials that could be harmful? Just wondering.
Wow, this is game-changing stuff. I mean, imagine the applications for medical tech alone. Just blows my mind.
Optical vortex lasers, huh? Thats the kinda term that makes you wanna go back to school and study physics or something.
