Text of Abstract
Nikola Dudukovic and co-workers produce transparent glass with spatial change in refractive index by 3D printing suspensions (inks) of silica nanoparticles and a titania precursor dopant. A predictive methodology is developed to allow formulation of inks with targeted rheology and matching solids concentrations for multimaterial 3D printing. This presents a vital step towards additive manufacturing of functionally designed optical components. *This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344 within the LDRD program (16-SI-0003).
