Description

This study focused on the production of the magnetostrictive filaments and the 3D printing with them. The research goals were to improve filament quality and magnetostrictive responses by finding more efficient ways for creating filament and developing optimal methods for 3D printing. For the fabrication of magnetostrictive filaments, Terfenol-D (a giant magnetostrictive material) powders were incorporated into an acrylonitrile butadiene styrene (ABS) thermoplastic matrix. The resulting filaments inherited the magnetostrictive properties of Terfenol-D with enhanced mechanical properties of ABS as well as improved alternating current responses owing to the reduction of eddy current by the ABS matrix. A new procedure for producing filament was developed based on lessons learned from previous methods and led to better control of filament properties and a higher success rate of fabricating quality parts with the modified 3D printer. Since the 3D printing process has shown improved magnetostrictive particle alignment, new printing patterns were developed to take advantage of this feature.
