“…In the past few decades, the development of additive manufacturing technology has promoted the extensive research on microlattice structures. Many lattice structures with excellent mechanical properties, such as body-centered cubic (BCC), octet-truss (OT), and rhombic dodecahedron (RD), have been studied and their mechanical properties were optimized, in order to be used in different engineering fields [12][13][14][15]. With the rapid development of advanced manufacturing technology, the development of engineering materials has shown obvious trends toward light weight, integration, functionalization, and biomimicry [16].…”

The lattice metamaterial has attracted extensive attention due to its excellent specific strength, energy absorption capacity, and strong designability of the cell structure. This paper aims to explore the functional nickel plating on the basis of biomimetic-designed lattice structures, in order to achieve higher stiffness, strength, and energy absorption characteristics. Two typical structures, the body-centered cubic (BCC) lattice and the bioinspired hierarchical circular lattice (HCirC), were considered. The BCC and HCirC lattice templates were prepared based on DLP (digital light processing) 3D printing. Based on this, chemical plating, as well as the composite plating of chemical plating followed by electroplating, was carried out to prepare the corresponding nickel-plated lattice structures. The mechanical properties and deformation failure mechanisms of the resin-based lattice, chemically plated lattice, and composite electroplated lattice structures were studied by using compression experiments. The results show that the metal coating can significantly improve the mechanical properties and energy absorption capacity of microlattices. For example, for the HCirC structure with the loading direction along the x-axis, the specific strength, specific stiffness, and specific energy absorption after composite electroplating increased by 546.9%, 120.7%, and 2113.8%, respectively. The shell–core structure formed through composite electroplating is the main factor for improving the mechanical properties of the lattice metamaterial. In addition, the functional nickel plating based on biomimetic structure design can further enhance the improvement space of mechanical performance. The research in this paper provides insights for exploring lighter and stronger lattice metamaterials and their multifunctional applications.

“…Moreover, honeycomb structures offer effective energy absorption under impact and shock stress [4,5]. Researchers have already proven that lattice structures are light in weight, have high impact strength, and have high energy absorption capability [6,7]. The mechanical outcome of various cellular arrangements like an octet, tetrahedral, pyramidal, square, and Kagome were investigated by different researchers during the early progress in research of micro-lattices [8][9][10][11][12][13][14][15][16][17][18].…”

Modern-era researchers are interested in searching for new durable and sustainable materials. Cellular structures are the novel solution which exhibits high strength. Micro lattice structures are systematically arranged structures with a high strength-to-weight ratio. Micro Lattice structures can be utilized widely as thermal insulators, energy, and vibration absorber in aircraft and automobile sectors. This study compares the mechanical characteristics of various BCC topologies that are frequently used today. Seven different types of cellular structures with different topologies viz. BCC, BCC enhanced, and BCCz , along with varied unit cell sizes and variations in strut diameter, were fabricated using SLS method. The primary cube was prepared as BCC (Body-Cubic Centered), BCC enhanced, BCCz type with 2×2×2 mm sizes. The SS316 metal was used for these initial cells because to its superior corrosion resistance and improved mechanical performance. These primary cells were repeatedly constructed with patterns in the three X, Y, and Z axes, resulting in total sample sizes of 20 × 20× 20 mm.FE analysis was performed using an FEA solver, and results were compared with experimental results. The result shows that BCCz exhibits superior mechanical properties, whereas BCC enhanced has more strength than regular BCC topology. The BCCZ showed a 62% rise in stresscarrying capacity compared to traditional lattice structure, whereas BCC enhanced showed the 22% rise in stresscarrying capacity. The consequence of size of unit cell is inspected for the outcome of lattices. The smaller unit cell lattice shows more significant yield stress for traditional BCC and enhanced BCC structure. Such a study can undoubtedly open doors for further research on the change in various topologies on the mechanical attributes of lattices under different loading conditions.
