Additive manufacturing via 3-D printing has become a frontier in materials research, including its application in the development and recycling of permanent magnets. We present a mathematical framework which predicts the degree of alignment (DoA) in an in-situ aligned 3D printed bonded magnets. A multiphysics model is developed which couples the harmonious interactions of magnetic particles in a viscous polymer under an external magnetic field. Experimental validation of DoA predictions is performed using Nd-Fe-B+Sm-Fe-N in Nylon12 and Sm-Co in PLA. A parametric analysis is performed to study the effect of alignment field strength, magnetic loading fraction, extrusion load, and particle size on DoA. The model predicts a competing behavior between particle-fluid and particle-particle interactions under an applied magnetic field. The model provides a framework to efficiently predict the DoA in tandem with a functionalized-magnetic 3D printer and allows the user to adjust the operating parameters according to the desired DoA.
