More Information
Summary:Methods and systems for Laser-Induced Forward Transfer are disclosed in which a microfluidic chip is used as the printing head. The head comprises a transparent upper region, a middle region comprising an intermediate layer channel and an ink channel in fluid connection with said intermediate layer channel, and a lower layer with an orifice in fluid contact with the ink channel. When material in the intermediate layer channel is irradiated by an energy source (typically a pulsed laser) at a spot opposite the orifice, the material is partially evaporated, creating a vapor bubble that creates a transient pressure increase when it collapses, thereby forcing ink out of the orifice and onto a receiving substrate.
