Abstract: The present invention refers to a device and method for stereolithograpic three dimensional (3D) printing comprising: a) a container adequate for containing a photopolymerizable polymer, b) at least one laser generator emitting a light beam with a wavelength between 360 nm and 1000 nm, c) modulation means for modulating said light beam into at least two light sheets which are matrices of light, and d) means for irradiating said light sheets in the container containing said photopolymerizable polymer; wherein said at least one laser generator is arranged so that said at least two light sheets are crossed inside said container, leading to polymerization of the photopolymerizable polymer at the crossing of said light sheets.

Abstract: The technology disclosed relates to developing an acousto-optic device (AOD) using an alpha-barium borate (?BBO) crystal. An AOD using ?BBO enables high-resolution microlithographic patterning. The AOD includes a slab of ?BBO coupled to an RF transducer that drives an acoustic wave through the crystal structure. A laser source emits a beam of light that is incident on the crystal surface. The propagated acoustic wave acts as a diffraction grating that diffracts the incident wave. Using an ?BBO crystal allows for high resolution of light in the ultraviolet and visible spectra. The low speed of acoustic wave propagation through the crystal allows for more laser spots to be imaged than AODs made using other types of crystals.
