The authors discuss the process of ceramic-polymer filament obtaining based on aluminum oxide (Al
2 O3 ) and polylactide (PLA) for its use in 3D printing technology by fused deposition modeling method (FDM). They consider ceramic polymer compositions with the following component ratio: 30% PLA and 70% Al2 O3 ; 40% PLA and 60% Al2 O3 ; 50% PLA and 50% Al2 O3 . The compositions were obtained by the colloidal method on a ball mill in distilled water, followed by drying in a vacuum oven and sieving. The microstructure and elemental composition of the mixtures have been studied. The modes of extrusion of the obtained ceramic-polymer compositions are selected. The most advantageous composition of a ceramic-polymer mixture of 40% PLA and 60% Al2 O3 has been determined for further use in creating three-dimensional objects by FDM. Experimental samples of products from the produced ceramic-polymer filament were printed. [ABSTRACT FROM AUTHOR]- Published
