World’s Smallest Image printing using 3D NanoDrip Technology


ETH Zurich and a startup called Scrona Ltd. have been announced world record holders for the smallest inkjet-printed color image. They used 3D NanoDrip printing technology to print a tiny image of clown fish around a sea anemone.  The image is of the size of a cross section of a human hair.  The image is 0.0092 mm2 in area and can only be seen under a microscope.

The image is printed using nano particles called quantum-dots.  Quantum-dots can emit lights of different colors depending on their size.  Layers of red, green, and blue quantum dots can be created to generate different colors.

Scrona also developed µPeek, a credit card sized microscope that can be used to see the tiny image.  The microscope can be interfaced with smartphones allowing you to see it using the smartphone and to take pictures of the image.





3D Printed Microscopic Robotic Fish

According to the researcher Wei Zhu, “developing the technology Nano-engineers at the University of California,  San Diego has been able to 3D print microscopic robots.  They developed tiny robots shaped like fish.  These are called microfish and are smaller than the width of human hair.  Nanoparticles are added to various parts of the microfish to make them functional.  Platinum nanoparticles installed in their tails help them propel forward.  Magnetic nanoparticles installed in their head can be used to steer them.

The microfish are developed using a 3D printing technology called microscale continuous optical printing.  This technology allows 3D printing hundreds of microfish within seconds. The shapes of the microbots to be changed, for example, to experiment with different shapes of fish such as sharks vs. ray fish, or experiment with other shapes such as birds.

We have developed an entirely new method to engineer nature-inspired microscopic swimmers that have complex geometric structures and are smaller than the width of a human hair. With this method, we can easily integrate different functions inside these tiny robotic swimmers for a broad spectrum of applications.”  For example, toxic neutralizing particles can be included in the microfish to use them for detoxifying liquids.  In future, this technology may allow delivery of medicine to specific parts of the body via a bloodstream”.
