“…The inherent geometry distributes material efficiently, resulting in lightweight components. The interconnected cells create a lattice-like framework that disperses loads evenly throughout the structure, enhancing its ability to withstand forces, including compression [30]. This is especially crucial in applications like aerospace and automotive, where lightweight components improve fuel efficiency and overall performance.…”

Fused deposition modelling (FDM) as one of 3D printing technique allow for the layer-by-layer construction of objects from a CAD file using a variety of different materials. The process has become quicker and more versatile as a result of technological innovation. In this study, the Taguchi method and Grey Relational Analysis (GRA) were integrated to examine the mechanical performance and topology optimisation of polylactic acid (PLA) 3D printed hollow and thin-walled structures by FDM. The results showed that the optimized factors for the 3D printed part were identified as topology design (hexagonal), wall thickness (2 mm), layer height (0.2 mm), infill density (20%), infill layer thickness (0.6 mm), infill flow (80%), infill pattern (Triangle), print speed (100 mm/s), printing temperature (210°C), bed temperature (65°C), and orientation direction (flat along the Y-axis). The compression properties of the 3D printed part particularly for maximum force, maximum stress and compression modulus were improved by 15.42%, 66.62% and 68.61% respectively after the optimization.

“…Honeycombs inspired by nature are common AM structures due to their high relative mechanical properties per weight. Mechanical testing has demonstrated that increases in material distribution at honeycomb nodes increases both stiffness and absorbed energy but may weaken other aspects of the structure if material volume is further increased [16]. The design of more complex architected structures, such as regular truss lattice cells, is another AM configuration strategy that enables mechanical efficiency [63] (Figure 4).…”

“…During design generation, parameter alterations for lattices may affect print accuracy and the reaction loads of structures [15]. During assessment, such as testing the mechanics of honeycomb structures, finite element (FE) models have been created that facilitate computational design with accurate predictions of structural performance [16]. Using these techniques can aid in the creation of novel systems using AM, such as multihelical springs with experimentally validated stiffness predictions [17].…”

Design for additive manufacturing (DfAM) provides a necessary framework for using novel additive manufacturing (AM) technologies for engineering innovations. Recent AM advances include shaping nickel-based superalloys for lightweight aerospace applications, reducing environmental impacts with large-scale concrete printing, and personalizing food and medical devices for improved health. Although many new capabilities are enabled by AM, design advances are necessary to ensure the technology reaches its full potential. Here, DfAM research is reviewed in the context of Fabrication, Generation, and Assessment phases that bridge the gap between AM capabilities and design innovations. Materials, processes, and constraints are considered during fabrication steps to understand AM capabilities for building systems with specified properties and functions. Design generation steps include conceptualization, configuration, and optimization to drive the creation of high-performance AM designs. Assessment steps are necessary for validating, testing, and modeling systems for future iterations and improvements. These phases provide context for discussing innovations in aerospace, automotives, construction, food, medicine, and robotics while highlighting future opportunities for design services, bio-inspired design, fabrication robots, and machine learning. Overall, DfAM has positively impacted diverse engineering applications, and further research has great potential for driving new developments in design innovation.

“…Different lattice structures were investigated in Nazir et al (2022) using a uniaxial compression test to get the energy absorption characteristics while conducting a tensile test as well to get the mechanical properties of that used material. Nazir et al (2022) concluded that distributing more material near the edge would enhance the energy absorption characteristics, and the square honeycomb configuration has better results than other structures. Nazir et al (2022) used Multijet Fusion Technology for manufacturing these structures, and this proposed study focuses more on parts that are manufactured using FDM technology.…”

3D printing technology is the new frontier in building construction. It is especially useful for making small structures within a short period. Full construction, including interior partitions and exterior façades, can be achieved with this technology. This paper proposes a parametric Voronoi tessellations model for quickly generating and fabricating 3D-printed hexagonal honeycomb partitions for interior design. Comprehensive experimental testing was conducted to characterize the mechanical properties and investigate the energy absorption characteristics of the proposed 3D-printed hexagonal honeycomb while comparing it to alternative hexagonal honeycomb structures. The tests included tensile testing (ASTM-D638) of the printed Polylactic Acid (PLA) material, especially with the almost total absence of conducted research that reported mechanical properties for 3D printed material with low infill percentages such as 10%. In addition, an in-plane quasi-static axial compression testing of the lightweight honeycomb structures was also conducted on the printed structure with the same low infill percentage. Compared to non-Voronoi honeycomb structures, the Voronoi honeycomb resulted in superior mechanical and energy absorption properties with energy absorption values ranging from 350 to 435 J and crash force efficiency being 1.42 to 1.65.
