HoloTile superimposes multiple holograms eliminating random light interference for efficient and high-resolution 3D printing

https://www.eurekalert.org/news-releases/1073411

"projecting 3D hologram of shape onto spinning resin/ hydrogel vial... utilizes projected light waves' phase/ position, so all pixel inputs contribute to holographic image in all planes, giving more light efficiency/ better spatial resolution in final 3D object... prints complex 3D objects <60 seconds, 25X less optical power... hologram beams can be made self-healing spreading through resin without thrown off course by small particles... standard commercial equipment... biomedical... future: no need to spin vial"
