Over millions of years of natural evolution, organisms have developed nearly perfect structures and functions. The self-fabrication of organisms serves as a valuable source of inspiration for designing the next-generation of structural materials, and is driving the future paradigm shift of modern materials science and engineering. However, the complex structures and multifunctional integrated optimization of organisms far exceed the capability of artificial design and fabrication technology, and new manufacturing methods are urgently needed to achieve efficient reproduction of biological functions. As one of the most valuable advanced manufacturing technologies of the 21st century, laser processing technology provides an efficient solution to the critical challenges of bionic manufacturing. This review outlines the processing principles, manufacturing strategies, potential applications, challenges, and future development outlook of laser processing in bionic manufacturing domains. Three primary manufacturing strategies for laser-based bionic manufacturing are proposed: subtractive manufacturing, equivalent manufacturing, and additive manufacturing. The progress and trends in bionic subtractive manufacturing applied to micro/nano structural surfaces, bionic equivalent manufacturing for surface strengthening, and bionic additive manufacturing aiming to achieve bionic spatial structures, are reported. Finally, the key problems faced by laser-based bionic manufacturing, its limitations, and the development trends of its existing technologies are discussed.

“…Inspired by the structure of the Norway spruce trunk, Lin et al proposed a gradient honey-comb structure for thermal insulation. [247] Four different structures of honeycomb are shown in Figure 14f, the gradient and nongradient honeycombs were designed in the sandwich panel. By measuring the thermal conductivity and thermal resistance of the different structures, it can be found that the GB structure possesses the lowest thermal conductivity and the highest thermal resistance (Figure 14g).…”

The natural design and coupling of biological structures are the root of realizing the high strength, toughness, and unique functional properties of biomaterials. Advanced architecture design is applied to many materials, including metal materials, inorganic nonmetallic materials, polymer materials, and so on. To improve the performance of advanced materials, the designed architecture can be enhanced by bionics of biological structure, optimization of structural parameters, and coupling of multiple types of structures. Herein, the progress of structural materials is reviewed, the strengthening mechanisms of different types of structures are highlighted, and the impact of architecture design on the performance of advanced materials is discussed. Architecture design can improve the properties of materials at the micro level, such as mechanical, electrical, and thermal conductivity. The synergistic effect of structure makes traditional materials move toward advanced functional materials, thus enriching the macroproperties of materials. Finally, the challenges and opportunities of structural innovation of advanced materials in improving material properties are discussed.

“…With the development of launch and hypersonic vehicles, more complex geometries have been applied to the design of integrated thermal protection (ITP) structures. [ 67 ] Inspired by the structure of the spruce stem (Figure 15d), Kaijie Lin et al [ 203 ] used SLM to fabricate a series of ITP structures with different graded hollow tubular sections (Figure 15e,f) via SLM, resulting in the lowest bottom surface temperature of 263 °C (Figure 15g–l), which was 21 °C lower than that of other structures. Zhang et al [ 100 ] created a graded multi‐metal heat exchanger with a designed graded structure, which displayed better thermodynamic properties (e.g., pressure drop, temperature distribution, and heat transfer coefficients, Figure 15m–o) and improved the heat distribution performance by about 20–30 W·m −2 ·K −1 compared to those of a conventional heat exchanger with a uniform honeycomb structure.…”

Functionally graded materials (FGMs) and functionally graded structures (FGSs) are special types of advanced composites with peculiar features and advantages. This article reviews the design criteria of functionally graded additive manufacturing (FGAM), which is capable of fabricating gradient components with versatile functional properties. Conventional geometrical‐based design concepts have limited potential for FGAM and multi‐scale design concepts (from geometrical patterning to microstructural design) are needed to develop gradient components with specific graded properties at different locations. FGMs and FGSs are of great interest to a larger range of industrial sectors and applications including aerospace, automotive, biomedical implants, optoelectronic devices, energy absorbing structures, geological models, and heat exchangers. This review presents an overview of various fabrication ideas and suggestions for future research in terms of design and creation of FGMs and FGSs, benefiting a wide variety of scientific fields.
