“…Figure 1b shows some of the characteristics of a printed HTRP sandwich panel section. The sandwich panel consists of a bottom skin with a thickness varying from 2-5.8 mm, a 16 mm thick core inspired by Helmholtz resonators [24,51] printed as a single extrusion wall of 0.4 mm thick, and a 12 mm thick top skin, comprising a grid infill. An analysis of the Euclidean distance between the computer-assisted drawing (CAD) model and the scan mesh of one of the printed panel sections (Figure 1c) revealed HTRP sandwich panel assembly on the aircraft casing, 3D scanning of the top surface topography, and multinozzle toolpath generation, 3) non-planar multinozzle AM of abradable thermosetting microscaffold networks on top of HTRP panel assembly.…”

“…[ 23 ] Even though, use of low‐performance polylactic acid has been investigated for the FFF of a planar multifunctional (i.e., mechanical and acoustic) sandwich panel. [ 24 ] A sandwich panel is a structure made of a thick low‐density core encased in thinner top and bottom skins, and is a popular structural aircraft component. The 3D‐printed sandwich panel was ≈205 mm × 76 mm × 36 mm, and had a stiffness of up to ≈10% higher than that of standard hexagonal honeycomb sandwich structure.…”

Multiprocess additive manufacturing (AM) consists of integrating different 3D printing techniques to enable the fabrication of multifunctional parts, based on their geometry and material properties. The combination of fused filament fabrication (FFF) and direct ink writing (DIW) techniques, respectively involving thermoplastics and thermosetting polymers (or composites), often focuses on planar and small‐scale applications (i.e., few cm), with limited nozzle orientation freedom for the fabrication of complex parts. Many industries, such as the aerospace sector, could benefit from the AM of lightweight multifunctional parts. For instance, one of the key aircraft components, the abradable seal coating, is applied on gas turbine engines casing to increase engine efficiency and is mechanically abraded by the rotor blades during engine startup. Abradable coatings made of thermosetting polymer could be 3D‐printed using a multiprocess to obtain more functionalities. In this work, a non‐planar multiprocess AM approach involving FFF of a complex large sandwich panel structure with low material density and large‐scale DIW of an abradable thermosetting coating with controlled porosity for sound absorption potential, and better mechanical abradability than a commercial product, is presented. This multiprocess AM approach can be used to manufacture lightweight multifunctional structural parts for the automotive or aerospace industries.

The interest in novel mechanical metamaterials that offer advanced functionalities and mechanical tunability for highly compatible multifunctional performance in state‐of‐the‐art engineering applications is growing. Here, a novel tunable multifunctional mechanical metamaterial, also known as a metamaterial sandwich panel, which can achieve load‐bearing, energy absorption, and low‐frequency vibration isolation properties simultaneously, is reported. The designed metamaterial sandwich panel is composed of a quasi‐zero stiffness (QZS) lattice core and two kirigami‐style surfaces, which endow the metamaterial sandwich panel with multi‐function performance and tunable properties. As a proof‐of‐concept, the mechanical properties and tunable multifunctional performance of the proposed metamaterial sandwich panel are demonstrated both in simulations and experiments. This work provides a new alternative for designing novel mechanical metamaterials with tunable multifunctional performance and may have potential applications in a variety of engineering applications, such as medical transportation, marine systems, and aerospace applications.

Additive manufacturing (AM) is a revolutionary technology that enables production of intricate structures while minimizing material waste. However, its full potential has yet to be realized due to technical challenges such as the dependence of part quality on numerous process parameters, the vast number of design options, and the occurrence of defects. These complications may be magnified by the use of polymers and polymer composites due to their complex molecular structures, batch‐to‐batch variations, and changes in final part properties caused by small alterations in process settings and environmental conditions. Machine learning (ML), a branch of artificial intelligence, offers approaches to tackle these challenges and significantly reduce the experimental and computational time and expense. This review provides a comprehensive analysis of existing research on integrating ML techniques into polymer AM. It highlights the challenges involved in adopting ML in polymer AM, proposes potential solutions, and identifies areas for future research.
