In this paper, we experimented to determine the ideal ratio of magnetic properties/PLA composites for creating magnetic filaments for FDM 3D printing. To achieve this, we created 15 samples using the control variates method, analyzing factors such as the type of material used, the powder size of the magnetic substance, and PLA pellet size. Also, Our approach utilized a novel method of combining the sol-gel and co-blending methods to produce uniform and high-induced magnetic field strength properties in the magnetic substance/PLA binary composites. By comparing Maximum tesla measurement results, we determined that using NdFeB is preferable to Fe3O4 in our particular conditions. We found that the composites’ magnetic properties depend only on the materials and mass ratio of the magnetic substance, with the ideal ratio being 2: (4-6): 8 for binders, magnetic substances, and PLA, respectively. Finally, based on our findings, we produced a sample filament and suggested possible applications.

“…Magnetic materials, however, still remain far behind this digital fabrication revolution [3] despite the fact that magnetic materials hold great promise for interactive applications. For example, researchers used magnets to create novel tangible interfaces (MechaMagnets [18]), to produce custom tactile sensations (MagneLayer [16]), to guide the assembly of 3D objects (DynaBlock [12], ElectroVoxel [6], Stochastic Self-assembly [5]), and to create actuated interfaces (Programmable Polarities [10]). However, all of these works either use of-the-shelf magnets (MechaMagnets [18], DynaBlock [12]) or require manual construction of the customized magnetic materials (FluxPaper [11], MagneLayer [16]).…”

“…not interacting magnetically) in other orientations. We accomplish this by evaluating the 2D cross-correlation between the matrices representing these pixel patterns and choosing only those matrices that maximize mutual agnosticism between pairs [9]. Finally, our system can vary the magnetic force of Mixels continuously (N to S) rather than just discreetly (N or S).…”

In this demonstration, we present Mixels, programmable magnetic pixels that can be rapidly fabricated using an electromagnetic printhead mounted on an of-the-shelve 3D printer. The ability to program a magnetic material pixel-wise with varying magnetic forces enables Mixels to create new tangible, tactile, and haptic interfaces. To facilitate the creation of interactive objects with Mixels, we provide a user interface that lets users specify the high-level magnetic behavior and that then computes the underlying magnetic pixel assignments and fabrication instructions to program the magnetic surface. Our custom hardware add-on based on an electromagnetic printhead clips onto a standard 3D printer and can both write and read magnetic pixel values from magnetic material. Finally, we highlight the importance of fundamental magnet parameters such as coercivity and remanence in designing a magnetic plotter, and show how leveraging 2D plotting enables a number of interactive applications.
