摘要

This study reports the development of printable magnetic nanocomposites designed with a novel nanotextured surface, featuring nanospikes—composed of iron oxide magnetic nanorods—distributed with a subtle vertical alignment tendency, inspired by the Beam Drop Inhotim artwork,termed here “Beam Drop Inhotim Surfaces” (BDIS). The nanorods were synthesized via reflux and hydrothermal routes, then incorporated into a commercial photopolymerizable resin, forming a printable magnetic nanocomposite. It was printed using masked stereolithography (MSLA) 3D printing process, with real-time application of a neodymium magnet-induced magnetic field during photopolymerization—an innovative approach compared to plasma or laser surface treatments used in other studies. Characterizations of the nanorods, photosensitive resin, and nanocomposite, conducted via Fourier-transform infrared spectroscopy, magnetic force microscopy, scanning electron microscopy, and vibrating sample magnetometry, confirmed successful nanocomposite production without compromising printability, enabling a unique nanotextured surface.
