The present invention includes a system, apparatus and method for generating a three-dimensional image and/or printing a three-dimensional structures, the system comprising: a medium comprising an acid-sensitive photoinitiator, a photoacid, monomers, donors, and acceptors, wherein the acceptor has a non-fluorescent state and a fluorescent state, wherein at one wavelength of optical excitation an optical molecular switch molecule has a first state, and at a second state the optical molecular switch molecule fluoresces at a second wavelength of excitation; and at least a first light source and a second light source into the medium, wherein light emitted by the at least first and second light sources are directed to contact the acid-sensitive photoinitiator, wherein a first wavelength activates the photo acid, and the second wavelength triggers polymerization of the monomers.

An inkjet print apparatus includes a stage; an inkjet head located over an upper portion of the stage, configured to move in a first direction and a second direction opposite to the first direction, and configured to eject an ink toward the stage; a first ultraviolet irradiator located behind the inkjet head with respect to the first direction first covers located at respective sides of the first ultraviolet irradiator in the first direction; a second ultraviolet irradiator located behind the inkjet head with respect to the second direction; and second covers located at respective sides of the second ultraviolet irradiator in the second direction. Further, a process for forming an adhesive layer may be simplified by using an inkjet printing method.
