| Abstract: | In this report a methodology is proposed to chemically produce the magnetic PLA/Fe3O4 composite material. Additionally, a methodology for making a filament from the prepared material is proposed. This filament was used with an FDM printer to produce parts with a compliant hinge. These parts were magnetized and the possibility to actuate the parts with a magnetic field was investigated. Lastly, the material and printed parts were tested on mechanical and magnetic properties. The methodology proposed to produce the PLA/Fe3O4 composite material showed good results. With this material filament has been made, for which the methodology has shown good results as well. This filament was then used with an FDM printer, again showing good results. The magnetite was found to be nearly homogeneously mixed throughout the filament and the SEM analysis showed good dispersion of the magnetite particles and little agglomerate formation. The mechanical properties of the printed samples were found to comply with properties found in other literature. Additionally, the possibility of actuating the prepared material was investigated. It was found that the magnetite showed significantly lower remanence than expected. As a result the samples were not able to be actuated. |
