  Nd-Fe-B bonded magnets are an important class of permanent magnets, employed
in many technological sectors. The Additive Manufacturing (AM) processes
enables the fabrication of net-shape bonded magnets with complex geometries,
allowing to tailor their magnetic stray field specifically for a given
application. A crucial challenge to be addressed concerning AM of bonded
magnets is the production of magnetically anisotropic components. The common
approaches presented in the literature up to now, required a post-printing
procedure or the complex integration of a magnetic field source into the AM
process. Here, we present a technique to fabricate anisotropic bonded magnets
via Laser Powder Bed Fusion (LPBF) by utilizing the mechanical alignment of
anisotropic particles in a single step, without the need for a magnetic field
source. Anisotropic bonded magnets were fabricated using a mixture of
anisotropic Nd-Fe-B powder (MQA-38-14) and polyamide-12 (PA12). This magnetic
powder consists of ellipsoidal particles, where the easy magnetization axis is
distributed perpendicular to their longest side, which can be exploited to
generate magnetic texture. Depending on the particle size used as feedstock,
the degree of alignment (<cos$(\theta)$>) can be tailored to a maximum of
<cos$(\theta)$> = 0.78. The fabricated anisotropic bonded magnets exhibited a
maximum remanence of Jr = 377 mT and an energy product of (BH)max = 28.6 kJ/m3,
respectively.
