摘要：
In this study, we employed fused deposition modeling (FDM) to fabricate polylactide (PLA) composites with 5 wt% and 10 wt% of CoFe2O4 (CFO) magnetic nanoparticles. The structural, mechanical, and magnetic properties of these nanocomposites were studied. Tensile testing revealed that as the concentration of CFO increased, both the tensile strength, from 26 MPa to 7 MPa, and deformation limits, from 4 % to 1 %, decreased. However, atomic force microscopy analysis showed an increase in the average Young's modulus of the surface. The results of magnetic measurements demonstrated that 3D technique enables one to controllably print the patterns which serve as the sources of local magnetic fields of complex geometries.
