Acoustic levitation-assisted contactless droplet printing

A method for universal contactless printing comprises depositing a first droplet into a sound field, curing the droplet to form a cured droplet, depositing a second droplet, and securing the second droplet to previously cured droplet by curing the second droplet. The method of contactless printing can be repeated to form a complex three-dimensional structure. The first droplet that is deposited can be secured to a moveable structure by curing the first droplet to the moveable structure. The moveable structure can be moved to place a next droplet to be deposited and cured.
