Latest Hot News: Sound Enabled Printing Technology
Printing and publishing is always a hot news in some nations because of the content it put forward to the readers.But the good news is that printing technology has improved from snail speed printing machines to supersonic extreme speed electronic printing machines,so the technological inventions is the hot news regard to printing.

Recently Harvard University research team has developed the sound enabled printing technology,that uses acoustic levitations.The new printing technology that uses sound waves to control the size of liquid droplets independent of fluid viscosity .This technique could finally enable the manufacturing of many new biopharmaceuticals, cosmetics, and food and expand the possibilities of optical and conductive materials.
Liquid droplets are used in many applications from printing ink on paper to creating microcapsules for drug delivery. Inkjet printing is the most common technique used to pattern liquid droplets, but it’s only suitable for liquids that are roughly 10 times more viscous than water. Yet many fluids of interest to researchers are far more viscous.
For example, biopolymer and cell-laden solutions, which are vital for biopharmaceuticals and bioprinting, are at least 100 times more viscous than water. Some sugar-based biopolymers could be as viscous as honey, which is 25,000 times more viscous than water.
The researchers built a subwavelength acoustic resonator that can generate a highly confined acoustic field resulting in a pulling force exceeding 100 times the normal gravitation forces (1 G) at the tip of the printer nozzle, that’s more than four times the gravitational force on the surface of the sun. This controllable force pulls each droplet off of the nozzle when it reaches a specific size and ejects it towards the printing target. The higher the amplitude of the soundwaves, the smaller the droplet size, irrespective of the viscosity of the fluid.
The researchers tested the process on a wide range of materials from honey to stem-cell inks, biopolymers, optical resins and, even, liquid metals. Importantly, sound waves don’t travel through the droplet, making the method safe to use even with sensitive biological cargo, such as living cells or proteins.

The sound enabled printing,acoustophoretic printing is a drop on demand method capable of patterning liquid metals, optical lenses and even cell -laden droplets.This technology is under research phase and may soon available on commercial markets.Sound enabled printing is expecting a revolution in pharmaceutical industry and other fields.
Actually it’s time to focus more on new possibilities of printing more and more items other and contents and letters.along with 3D printing ,more and more researches must happen in this printing world. Printing presses in Qatar ,now focusing on research also along with printing works to make creative and industrial printing to the next level of Artificial Intelligence.
So let’s have time to share some happy good news about printing and publishing than a marketing way of negative controversy which may harms both the industry and mind of good customers.
