“…B) was prepared by mixing the SE1700 base, the corresponding catalyst (Dow Corning) at a weight ratio of 10:1, and the other (denoted as Mat. C) contained SE1700 base, SE1700 catalyst, PDMS precursor, PDMS cure agent, and dibutyl phthalate (DBP, Sinopharm Chemical Reagent Co., Ltd.) as a foaming agent [ 54 ] at a weight ratio of 10:1:10:1:10. Above kinds of uniform inks were obtained by mixing at 2000 rpm for 3 min in a planetary mixer (ZYMC‐180V, ZYE Technology Co., Ltd.).…”

Vibration signals are essential data for the health monitoring of structures and the cyber–physical system. However, commercial vibration sensors are generally installed on struts/surfaces to gather raw data, which affects the result or causes the detachment problem. This study uses a facile 3D printing method to fabricate a smart vibration absorber with an interior multifunctional multimaterial elastic lattice (MMEL). These lattices, which work as vibration absorbers, have been demonstrated to possess the functions of self‐powered sensing and energy harvesting via the triboelectric effect. The triangular geometry parameter, materials type, etc. have been investigated to illustrate their basic mechanical and triboelectric properties and their coupled influence. Further, the results of the shock test show that MMEL can decrease the peak force from approximately 625 to 90 N and convey the Voc impulse signal simultaneously. The vibration signal has been collected through the MMEL to detect the vibration frequency and charge a watch simultaneously, demonstrating the feasibility and practical potential of the MMEL. The research provides a new method for constructing a multifunctional vibration absorber for applications.

Biological materials and organisms possess the fundamental ability to self‐organize, through which different components are assembled from the molecular level up to hierarchical structures with superior mechanical properties and multifunctionalities. These complex composites inspire material scientists to design new engineered materials by integrating multiple ingredients and structures over a wide range. Additive manufacturing, also known as 3D printing, has advantages with respect to fabricating multiscale, and multi‐material structures. The need for multifunctional materials is driving 3D printing techniques toward arbitrary 3D architectures with the next level of complexity. In this paper, we aim to highlight key features of those 3D printing techniques that can produce either multiscale or multimaterial structures, including innovations in printing methods, materials processing approaches, and hardware improvements. Several issues and challenges related to current methods are discussed. Ultimately, we also provide our perspective on how to realize the combination of multiscale and multimaterial capabilities in 3D printing processes and future directions based on emerging research.This article is protected by copyright.
