【 摘 要 】

We have developed technology of polysaccharides based matrices formation by laser stereolithography (SLA) method using UV range laser radiation. Experimental data on a laser parameters selection of single-layer structures polymerization for compositions based on unsaturated chitosan derivatives with different degree of substitution and with the addition of polyethylene glycol diacrylate is shown.
