This paper presents characterization of unconstraint depth photopolymerization yielding different forms of cured voxel under exposure of hollow Gaussian beam. The governing model consists of nonlinear Schrodinger equation along with transient diffusion phenomenon and intensity dependent refractive gradient is considered in predicting the curing behaviour. The effect of various process parameters viz; intensity of and degree of hollowness of Gaussian beam, time of exposure on the formation ofdoi:10.1088/1757-899x/577/1/012047 fatcat:mwfttfvdajdndmdp2lv3q4cz2e
