Summary: Tunable energy absorption achieved through grading of lattice structures has high potential for lightweight cellular cores in energy absorbing structures. This study investigates structurally graded and multi-material lattices consisting of plate-based octet unit cells, showing a near 10% increase in specific energy absorption in the plate thickness graded designs compared to baseline octet lattices. Finite element models were developed and showed good agreement with experimental results. The results demonstrate the capacity to adapt the octet lattice structure design through additive manufacturing to better suit the expected load and application.

Summary: In contrast to traditional 3D printing, conformal 3D printing enables structures to be created on non-planar surfaces, with a mathematical algorithm proposed to project printing trajectories onto such surfaces. The effectiveness of the algorithm is demonstrated through examples and comparisons with tessellated surfaces, showing that error depends on resolution rather than the algorithm itself.

Summary: Additive manufacturing, especially concrete 3D printing, is considered an interesting solution for remote development, enhancing local and national manufacturing and construction industries, and facilitating fast recovery after disasters. This study reviews the challenges of remote housing construction, focusing on Australia's Northern Territory (NT), and discusses the feasibility and efficiency of using concrete 3D printing to overcome these challenges. The advantages, limitations, and concerns of 3D printing for remote housing are presented, along with examples of completed 3D-printed construction projects in remote locations. Trade-offs between various aspects need to be considered to determine the practicality and desirability of 3D printing in remote areas, including materials, structural design, process efficiency, logistics, labor, and environmental impact. If local materials meet the requirements for printability, buildability, and robustness, 3D printing could be a cost-effective solution for remote housing. However, factors such as remote on-site fabrication, available local materials and their quality, and the limitations of large-scale manufacturing process and concrete 3D printing should be evaluated when comparing with conventional construction methods.

Summary: The challenging task of emulating the unique combination of structural, compositional, and functional gradation found in natural materials has been facilitated by recent innovations in additive manufacturing (AM) or 3D Printing (3DP). These techniques enable the creation of structures with variations in material composition, structure, and performance, giving manufacturers an edge in designing components for highly-specialized applications in different industries.

Summary: This review article summarizes recent advances in 3D food printing with a focus on current approaches to define the printability, optimize food ink formulas, mechanisms of AM technology, and suitability of food materials for 3D printing. Systematic manufacturing approach is crucial for understanding the 3DP process, and framing each step in the workflow may simplify research steps and accelerate high-quality 3DP for food applications. Redefining printability and summarizing existing approaches to obtain printable food materials will lay the foundation for future studies in this field.

Summary: Foam-like polyester composite materials were 3D-printed from a thermoset paste formulation, with the compressive performance of these lattice structures investigated under different humidity conditions and water immersion. Addition of 5 wt% coconut oil to the formulation prior to printing was found to decrease stiffness under dry conditions while increasing compressive strength after water immersion.

Summary: In this study, a pair of novel 2D re-entrant auxetic lattices capable of exhibiting enhanced stiffness and energy absorption is proposed by introducing vertical ligaments into conventional re-entrant structures. The deformation patterns and the energy absorption characteristics of the lattices were investigated via simulations and experiments. The results suggest that the proposed structures exhibit enhanced stiffness and superior energy absorption compared to conventional lattices.

Summary: This paper investigates an alternative method for machine tool base production using a concrete-filled additively manufactured polymer mold. The motion components are attached to the concrete base after curing. Modal testing results demonstrate that high damping and stiffness can be achieved with the concrete base construction, offering cost and lead time reduction compared to traditional methods.

Summary: The research focuses on the design, manufacturing, and testing of self-heating composite molds using large-scale pellet extrusion 3D printing technology. The results show that molds made of polycarbonate composites reinforced with carbon fiber and glass fiber can achieve uniform temperatures on their surfaces, but inner-bead voids and interfacial gaps have an impact on the mechanical properties of the composites. The stiffness of the wire-embedded mold is still satisfactory, indicating the technology's potential for additively manufactured out-of-oven/autoclave mold applications.
