Handling and assembling of low-density foam structures fabricated by two-photon polymerization

摘要: Low-density foam targets for laser induced shock wave propagation experiments were produced via direct writing from polymeric materials. These designed with dimensions of 2.0X0.25X0.3mm a density 100mg/cm 3 and included fully polymerized ablation layer, 15μm thick, written contiguously the low material in single fabrication step. We developed unique protocol order to assist release harvest glass substrate on which they fabricated. The process, as well assembly handling these delicate brittle samples is described this paper, demonstrating flexibility, versatility efficiency two photon polymerization technique that may complement conventional approaches materials fabrication. An ongoing research effort being conducted reduce minimum content stitching defects between target’s building blocks.
