Fig. 1: Principle and illustration of DISH.
From: Sub-second volumetric 3D printing by synthesis of holographic light fields
a, Multi-angle projection is used to generate 3D light intensity distributions within a fixed container for volumetric printing. b, A rotating periscope is designed to generate high-speed rotating projections of the light patterns modulated by a DMD within 0.6 s. The target model and its experimental printout are shown on the right as an example. c, Images captured at different time points showing that the printing process in a low-viscosity PEGDA aqueous solution can be finished within 0.6 s. d, Comparisons of the simulated 3D light distributions generated by the DISH system with incoherent light, coherent light without holographic optimization and coherent light with holographic optimization. The target ground truth is also shown on the left. Scale bars, 1 mm.
