Awesome invention! Working with sound waves!

#Developed by #scientists at #Harvard #University, the printer is able to adjust the size of the droplet in the nozzle and transfer it to the surface at speeds of up to 1000 meters / second. This acceleration is 100 times higher than the Earth's gravity on the sea surface, 3.5 times higher than the Sun's.

This new #printing #technique allows for the use of thick, non-fluid liquids that can not be used in printers at the beginning, or for medical procedures that require high precision. With this technique, scientists could use honey, stem cell based biological material and liquid metals to print.
Scientists who have been conducting long-lasting studies to control precisely the pressures that sound waves have applied to the objects that they hit have managed to keep the objects in the air with the sound waves ahead. Scientists who control the printer nozzle with sound waves with new work, control liquids that can not be used in place of ink or ink, with high sensitivity.
