At the present study the selective laser sintering/melting (SLS/M) process using the Nd +3 YAG laser was carried out to fabricate and characterize polymer composites based on nano-oxides of FexOy type or of high-temperature superconductivity (HTS) of SrFe12O19 with bioresorbable polycaprolactone (PCL) powders and manufacture porous tissue engineering scaffolds. Practicability of the method for synthesis of functional-gradient three dimensional (3D) parts with magnetic nano-oxide particles and structural ordering were shown and appropriated laser regimes were assigned. The stem cellular morphometry, proliferative and adhesive activity to the 3D magnetic nanocomposites were compared. The medical tests show that all the 3D printed composites have biocompatible features. Medical potential of the SLS/M-fabricated superparamagnetic nano oxides for application as cell targeting systems and tissue engineering scaffolds is being discussed.
