“…Also, multi-material 3D printing technology can cause anisotropy in the printed part, and the temperature gradient of the material due to layer-by-layer fabrication can also reduce the mechanical properties of each layer. The approaches to improve the mechanical strength of the multi-material 3D parts can be divided into two major groups: processing parameter optimization [ 211 , 212 ] and extra external energy input [ 213 , 214 ]. In addition to technical breakthroughs, fundamental scientific understanding on the inter-layer cohesion mechanisms between dissimilar printed materials is needed to push the boundary of multi-material additive manufacturing.…”

Multi-material additive manufacturing of polymers has experienced a remarkable increase in interest over the last 20 years. This technology can rapidly design and directly fabricate three-dimensional (3D) parts with multiple materials without complicating manufacturing processes. This research aims to obtain a comprehensive and in-depth understanding of the current state of research and reveal challenges and opportunities for future research in the area. To achieve the goal, this study conducts a scientometric analysis and a systematic review of the global research published from 2000 to 2021 on multi-material additive manufacturing of polymers. In the scientometric analysis, a total of 2512 journal papers from the Scopus database were analyzed by evaluating the number of publications, literature coupling, keyword co-occurrence, authorship, and countries/regions activities. By doing so, the main research frame, articles, and topics of this research field were quantitatively determined. Subsequently, an in-depth systematic review is proposed to provide insight into recent advances in multi-material additive manufacturing of polymers in the aspect of technologies and applications, respectively. From the scientometric analysis, a heavy bias was found towards studying materials in this field but also a lack of focus on developing technologies. The future trend is proposed by the systematic review and is discussed in the directions of interfacial bonding strength, printing efficiency, and microscale/nanoscale multi-material 3D printing. This study contributes by providing knowledge for practitioners and researchers to understand the state of the art of multi-material additive manufacturing of polymers and expose its research needs, which can serve both academia and industry.

“…The detection of mercury ions using low-cost, efficient, and highly stable sensors is of high priority due to the adverse effect of mercury on human health and the environment. Maya et al 226 prepared an environmentally friendly and reusable colorimetric solid-state sensor for detecting Hg 2+ ions using Na-bentonite (Na-Ben) nanoclay and a new synthetic quinaldine-functionalized calix [4]arene receptor (QHQC). Bentonite clays are able to expand their layers to incorporate organic molecules, thereby improving the overall properties of the hybrid structure in terms of mechanical, chemical, and thermal stability.…”

“…Clays are naturally derived layered aluminosilicate phases that are transformed with time. [1][2][3][4][5] Nanoclays are clay minerals with plastic properties and an ideal size (<100 nm) 6 that have an unusual ability to swell and mold in water. However, when dried, they retain the shape of the container.…”

The use of biodegradable polymers is a good strategy to overcome challenges induced by petroleum‐based polymers. However, in general, there exist limitations in the formulation and fabrication of biodegradable polymers to be used in the development of parts with targeted applications. The issue is more highlighted when the 3D printing of biodegradable blends needs to be addressed. This study examines the formulation and fabrication of biodegradable nano‐reinforced polymer blends to be used in fused‐filament 3D printing. The melt‐mixing method was utilized to prepare filaments and nanocomposite systems of polylactic acid (PLA)/thermoplastic starch (TPS) blends reinforced with 0–5 wt% of nanoclay. To better understand the feasibility of the formulated compound, the process–structure–property interplays in the PLA/TPS based specimens fabricated via the fused‐filament 3D printing and injection molding were investigated and compared. The findings revealed the molded specimens showed greater tensile and flexural behavior than the printed specimens, whereas the impact resistance of the printed and molded parts was comparable. It was shown that increasing nanoclay content led to the increase in the tensile strength, Young's modulus and flexural strength of the specimens regardless of the method used. The greatest tensile strength of 10.1 and 20.1 MPa was revealed at the optimized nanoclay content of 1 and 3 wt% in 3D printed and molded parts, respectively. The surface morphology demonstrated that the addition of nanoclay favorably contributed to the interfacial adhesion, confirmed by the mechanical response of the specimens. It was shown nanoclay enhanced the thermal stability and crystallinity of the specimens while reducing water absorption and biodegradability due to its barrier properties.
