“…In the large field of porous materials, foams have been fabricated for a long time following various methods, either chemical [1], [2], or physical [3], [4], [5]. On the one hand, chemical foaming requires the use of chemical blowing agents (CBA).…”

“…[9,12,13] The current solutions are based on two-stage approaches that consist in a first step where structures with interstrand macroporosity are printed and a second step where the intrastrand microporosity is produced by freeze-drying [13] or batch foaming. [12] Recently, a solution has been proposed where the first step consists of preparing either an emulsion [14] or a treated filament, [15] which, in the second step, is heated up through a 3D printer to produce the final foamed strand. Such approaches suffer the complexity of multistage processes and are seldom capable of fine control of the foamed strand morphologies.…”

We report the design and results of a novel process combining 3D printing and foaming to produce microfoamed polymeric structures, from simple strands to more complex architectures, using physical blowing agents. Foaming processes are extensively operated in polymeric cellular materials industry to produce pores, yet without spatial control of their positioning. This intrinsic stochasticity may introduce imperfections, which reduce the mechanical properties of the material, thus regular (e.g., periodic) porous structures would be more desirable. 3D printing allows to fabricate polymeric cellular materials with empty spaces in a well‐defined periodic structure. To this end, very expensive 3D printers are required to achieve micron‐resolution pores. Correspondingly, the production time is dramatically large and becomes a bottleneck to the industrial scale‐up. Herein, an innovative technique combining the simplicity of polymer foaming with the precision of 3D printing is presented. The resulting materials have the advantages of both the techniques: they have a micron‐controlled cell structure and can be printed at reasonable costs and time. The proposed approach is validated using a bio‐based and compostable polymer, namely, polylactic acid (PLA). The resulting foamed strands and hierarchical structures are novel in terms of morphology and show a controlled local porosity and superior mechanical properties.

“…[52,53] The precursor may contain particle fillers, mostly ceramic or conductive particles, in addition, biomaterials may also be used as precursors. [54] Benefits such as tweakable properties (i.e., hardness, biocompatibility, electrical properties, and flexibility) and multicomponent printing are possible due to the droplet printing features. [50,51] This AMT is capable of printing polymer matrix composites with nanomaterials as fillers with increased mechanical performances (e.g., tensile strength).…”

Superior electrochemical performance, structural stability, facile integration, and versatility are desirable features of electrochemical energy storage devices. The increasing need for high‐power, high‐energy devices has prompted the investigation of manufacturing technologies that can produce structured battery and supercapacitor electrodes with optimized charge transport. While conventional electrode production techniques are becoming increasingly obsolete and incompatible with technological developments such as wearables and flexible electronics, additive manufacturing (AM) has emerged as one of several state‐of‐the‐art tools to produce 3D‐structured electrodes with morphology control, high yield, and scalability. Herein, a comprehensive review of the major AM technologies and most recent literature about designing and manufacturing electrode materials for batteries and supercapacitors is presented. A thorough discussion of research opportunities and challenges in this promising field is also presented to introduce the potential and importance of AM to current developments involving electrode materials.
