3D Printing of ABS Barium Ferrite Composites

Hanemann, Thomas; Syperek, Diana; Nötzel, Dorit

Abstract (englisch):
In this work, a process for the realization of new polymer matrix composites with
nanosized barium ferrite (BaFe12O19) as ferrimagnetic filler, acryl butadiene styrene (ABS) as
polymer matrix and an extrusion-based method, namely fused filament fabrication (FFF), as 3D
printing method will be described comprehensively. The whole process consists of the individual
steps material compounding, rheological testing, filament extrusion, 3D-printing via FFF and finally
a widespread specimen characterization regarding to appearance, mechanical properties like tensile
and bending behavior as well as the aspired magnetic properties. Increasing ferrite amounts up to
40 vol.% (equal 76 wt.%) cause a reduction of the ultimate stress and an increase of the magnetic
polarization as well as of the energy product (BH)max in comparison to the pure polymer matrix. In
addition, an extensive discussion of typical printing defects and their consequences on the device
properties will be undertaken.
