3D printing enables the creation of intricate, layered structures with specific micro and macro architectures that cannot be achieved through traditional methods. By designing 3D structures with geometric precision, selective regulation of mechanical properties can be achieved, allowing for efficient dissipation of mechanical energy. In this study, a series of modular samples inspired by Bouligand structure were designed and produced through a direct ink writing system along with a classical printable polydimethylsiloxane (PDMS) ink. By changing the angles of filaments in adjacent layers of these modular samples (from 30° to 90°) and the filament spacing during printing (from 0.8 mm to 2.4 mm), they show adjustable mechanical properties. Compression mechanical testing revealed that the 3D printed modular Bouligand structures exhibit stress-strain responses that enable multiple regulation of elasticity modulus from 0.06 Mpa to over 0.8 Mpa. The mechanical properties were regulated over 10 times in printed samples prepared using homogeneous materials. The gradient control mechanism of mechanical properties during this process was analyzed using finite element analysis. Lastly, 3D printed customized modular Bouligand structures can be assembled to compose an array with Bouligand structures show different orientations and interlayer details according to specific needs. Begin with decomposing the original Bouligand structure to achieving modular 3D printing, and then assembling the modular samples into a special Bouligand structures array, this research will providing parameters for achieving gradient energy absorption structures.

In light of the escalating requisites for portability, functionality, comfort, and health in electronic apparatus, the imperative advancement of sophisticated multifunctional textile‐based triboelectric nanogenerators (textile‐TENGs) is underscored. This research delineates the fabrication of an innovative multifunctional textile‐TENG, comprising a photosensitive stratum aimed at thermal regulation and photothermal therapy, alongside a tribo‐negative nanofiber film adorning its verso. Exhibiting superlative electrical prowess, the textile‐TENG generates remarkably elevated outputs over a wide temperature range, thereby facilitating the efficacious conversion of kinetic energy derived from human motion into electrical energy. Concurrently, the device manifests an exceptional photothermal conversion efficiency, achieving instantly modifiable saturation temperatures (41.52–60.97 °C) under diverse solar exposures, rendering it eminently suitable for a broad spectrum of applications in thermal therapy and regulation domains. Significantly, within cold environments, the textile‐TENG demonstrates a capability to augment temperature by approximately 7.4 °C, markedly surpassing conventional cotton textiles in performance. In summation, the textile‐TENG is characterized by its unparalleled electromechanical attributes and photothermal conversion efficacies, concurrently facilitating thermal regulation, therapy, and electricity generation. This investigation not only furnishes a referential methodology for the development of advanced multifunctional textile devices but also substantially expands the conceivable application ambit of textile‐based technologies.
