“…In recent years, the focus has shifted towards the development of 3D-printable functional composites [ 25 , 26 ] with the vision of assisting (or in some cases, replacing) traditional manufacturing technologies. Numerous investigations of composite materials for FDM have been undertaken, involving filler materials such as glass [ 27 ], ceramics [ 28 , 29 , 30 , 31 ], and metals [ 32 , 33 ]; characterized for their thermomechanical [ 34 , 35 , 36 , 37 , 38 , 39 ], electric [ 40 , 41 , 42 ], dielectric [ 43 , 44 ], and ferromagnetic [ 45 ] properties. Other studies have looked at the magnetic properties of polymer matrix composites, including those with Ni [ 46 ], ferrite [ 47 , 48 ], and Nd-Fe-B [ 49 ] as functional materials.…”

In this work, a 3D printed polymer–metal soft-magnetic composite was developed and characterized for its material, structural, and functional properties. The material comprises acrylonitrile butadiene styrene (ABS) as the polymer matrix, with up to 40 vol. % stainless steel micropowder as the filler. The composites were rheologically analyzed and 3D printed into tensile and flexural test specimens using a commercial desktop 3D printer. Mechanical characterization revealed a linearly decreasing trend of the ultimate tensile strength (UTS) and a sharp decrease in Young’s modulus with increasing filler content. Four-point bending analysis showed a decrease of up to 70% in the flexural strength of the composite and up to a two-factor increase in the secant modulus of elasticity. Magnetic hysteresis characterization revealed retentivities of up to 15.6 mT and coercive forces of up to 4.31 kA/m at an applied magnetic field of 485 kA/m. The composite shows promise as a material for the additive manufacturing of passive magnetic sensors and/or actuators.

“…Thermogravimetric analysis was performed on the feedstock and filaments to investigate the composite’s filler content at each process step. Building upon a preliminary examination [47] of the ABS-BT composite, the print temperature and orientation of the test samples were optimized for the composites during the third process phase. Structural test samples were printed and characterized for their tensile and flexural properties.…”

A process for the development, characterization and correlation of composite materials for 3D printing is presented, alongside the processing of a polymer-ceramic functional composite using fused deposition modeling (FDM). The composite was developed using acrylonitrile butadiene styrene (ABS) as the matrix material filled with barium titanate (BT) micro-powder up to 35 vol % (74.2 wt %). The ABS-BT composites exhibited a shear thinning behavior with increasing ceramic content. The composite was 3D printed into structural and functional test samples using FDM by adapting and optimizing the print parameters. Structural characterization revealed increasingly brittle behavior at higher filler ratios, with the ultimate tensile strength falling from 25.5 MPa for pure ABS to 13.7 MPa for the ABS-35 vol % BT composite. Four-point flexural tests showed a similar decrease in flexural strength with increasing ceramic content. Functional characterization revealed an increase in the relative permittivity at 200 kHz from 3.08 for pure ABS to 11.5 for the composite with 35 vol % BT. These results were correlated with the Maxwell-Garnett and Jayasundere-Smith effective medium models. The process described in this work can be used for other 3D printing processes and provides a framework for the rapid prototyping of functional composites into functional parts with reliable properties. The ABS-BT composite shows promise as a functional dielectric material, with potential applications as capacitors and light-weight passive antennas.
